Session 1: The Measurement That Matters
Foundation - Dimensional Analysis
0%
Phase 1: Spark
FACILITATOR PREP — Read 20 minutes before class.
Pre-stage: 6 cylinders + 4 scales on the back table; per-pair tray with 1 syringe, 1 cup, 1 ruler, paper towels. Pre-fill 2 pitchers of room-temp water. Print 35 vitals log sheets.
Watch for: students reading the syringe at an angle (parallax — drives the deviation up) and skipping the tare step on the scale.
Success looks like: every pair's lowest deviation under 0.10 g by trial 3, and a leaderboard with at least 5 teams entered.
If it stalls: the heparin hook is the rescue — re-read the case aloud and ask 'who at this table just measured better than that nurse did?' That re-engages every time.
Woven notebook: open your notebook now. Use it to capture every prediction, partner discussion, and question that comes up in this phase. Your notebook is the record of your thinking.
Welcome to Session 1! Today you will pour, weigh, and measure your way through a precision drill, then hunt for the unit-mix-up that has killed real patients.
This first session sits at the intersection of every single pathway in this course: measurement you can trust. Healthcare, trades, biotech - they all start with units that cancel out cleanly.
The Hook
In 2006, a Methodist Hospital nurse gave a baby 10,000 units of heparin instead of 10 units. The vials looked identical. The decimal was in the wrong place. Three babies died that week at that one hospital.
The error was a unit mix-up. Same medication. Wrong math.
Your mission today is to learn the one skill that prevents this. It is called dimensional analysis - and you are being trained to be the person who catches the next near-miss before it leaves the pharmacy.
Conversion Factors and Dimensional Analysis
Tyler DeWitt walks through the unit-cancellation method you'll use today before you ever touch a syringe.
Foundations - Units Are Math Objects
In school, we treat '5' like a number. In the real world, '5' is nothing. '5 mL' is a dose. '5 mg' is a different dose. '5 mcg' is a third, totally different dose. The UNIT is part of the math.
Dimensional Analysis in Plain English
Step 1: Write what you have with its unit.
Step 2: Write what you want with its unit.
Step 3: Multiply by conversion factors so the unwanted units cancel out.
Example: You have 5 mL of a 2 mg/mL solution.
5 mL x (2 mg / 1 mL) = 10 mg
The mL cancels. You are left with mg. That's the answer.
1Talk to your partner: when have you measured something wrong and had it matter?
2What does 'significant figures' mean to you? (Guess if you are not sure.)
Phase 2: Build
Woven notebook: keep your notebook open as you build. Record your hypothesis, every measurement and observation, and what surprised you. Your notebook is your lab record for this session.
Materials per pair: 1 syringe (10 mL), 1 graduated cylinder (25 mL), 1 small cup, food coloring, water, paper towels, notebook. Per table: 1 digital kitchen scale (0.1 g resolution). 1 mL of water = 1.00 g, so 5.00 mL = 5.00 g - the scale is your truth-meter.
The Hypothesis
Your drug order says: 'Give 5 mL of a 2 mg/mL solution.' Before you touch anything, predict: how many total milligrams are you giving?
1Write your prediction in your notebook. Include the math. Include the unit.
The Build - Precision Pour Test
2Fill a cup with water and add 3 drops of food coloring. This is your 'solution.'
3Draw up EXACTLY 5 mL using the syringe. Read at eye level. Record the actual volume you drew.
How to Read a Syringe (3 mL, 1 mL, Insulin, 5 mL)
RegisteredNurseRN walks through reading the plunger line at eye level - the same technique you will use today.
4Pour that 5 mL into the graduated cylinder. Read at the meniscus (the curve) at eye level. Record the measured volume.
Measuring Volume Using a Graduated Cylinder
Two-minute demo of reading at the bottom of the meniscus at eye level; avoids parallax error.
5Calculate percent difference: (syringe reading - cylinder reading) / cylinder reading x 100. Is your syringe more precise or less precise than the cylinder?
6Repeat 3 times. Average your percent difference. Compare with another pair. Time-box: 10 min max.
7Now switch: repeat the whole 5 mL draw-and-pour test using ONLY the graduated cylinder (skip the syringe). Compare your percent difference. Which tool do you trust more now?. Time-box: 10 min max.
8Circle the trial with your LOWEST percent error. What did you do differently on that one? Share with your partner.
Real-world stakes: a syringe for a baby's meds is accurate to 0.1 mL. A graduated cylinder is accurate to about 1 mL. That's why nurses use syringes for tiny doses - a cylinder would kill a newborn.
The Challenge - Precision Pour Competition
Real nursing precision: pediatric meds are dosed to 0.1 mL. Today you find out how close YOU can get. The scale doesn't lie. 5.00 mL of water = 5.00 g.
9Tare the digital scale to zero with an empty cup on it. Draw what you believe is exactly 5.00 mL of water with your syringe. Dispense it into the cup. Record the scale reading to 0.01 g.
10Repeat 2 more times for 3 total trials. Calculate your absolute deviation each time: |reading - 5.00|. Average the 3 deviations. That average is your PRECISION SCORE - lower is better. Time-box: 10 min max.
11Write your team name + precision score on the whiteboard leaderboard. The team with the lowest average deviation wins the round.
12Round 2: each team gets ONE more attempt. Use what you learned (eye level, slow plunger, no air bubble at the tip). Best single deviation this round wins the bonus.
Real-world calibration: an experienced pediatric nurse hits within 0.05 g (1% deviation) on a 5 mL dose. A fresh CNA hits within 0.2 g (4%). Where did your team land? That gap is what training closes.
Phase 3: Apply
Woven notebook: as the answers come into focus, write them down. Note where the real-world numbers matched your prediction and where they were different. The reveal only sticks if you put it in your own words.
When the Math Goes Wrong
Case 1: Dennis Quaid's Twins (2007).
Actor Dennis Quaid's newborn twins received 10,000 units of heparin. The order was 10 units. A nurse grabbed the wrong vial - same color, same label style, 1,000x more concentrated. The twins survived. Many babies did not.
Case 2: The Emily Jerry Case (2006).
A 2-year-old died in Ohio after a pharmacy technician mixed a chemotherapy drug with 23% saline instead of 0.9%. A decimal place. A cancer patient. A funeral.
1Read above (1 min). Then continue.
Case 3: The Vicodin Overdose
An ER nurse gave 25 mg of morphine instead of 2.5 mg. The patient stopped breathing. One decimal. The patient lived because another nurse caught it in 90 seconds.
Every one of these errors had the same root cause: unit confusion. Every one was preventable with dimensional analysis. That's why we start here.

Session 2: Tools That Tell You What's True
Foundation - Precision + Measurement
0%
Phase 1: Spark
FACILITATOR PREP — Read 20 minutes before class.
Pre-stage: 4 calipers + 2 micrometers + 2 feeler-gauge sets at a shared tool table (NOT one per pair — students rotate). Lay out the machined-parts kits at 3 stations.
Watch for: students death-gripping the caliper jaws (compresses soft parts, false readings) and reading the wrong scale on the micrometer thimble.
Success looks like: pairs converge on the same measurement within ±0.02 mm by their third part, and at least one pair catches a part that's out of tolerance.
If it stalls: pull one pair forward and demo the 'thumb-light' caliper grip on the projector. The whole class watches once.
Woven notebook: open your notebook now. Use it to capture every prediction, partner discussion, and question that comes up in this phase. Your notebook is the record of your thinking.
Welcome to Session 2! Today you will measure the same object with three different tools, calculate percent difference, and find out which tool deserves to make the call.
This session sits at the intersection of every trade and lab in this course: tools that tell you what's true. The math is only as honest as the instrument behind it.
The Hook
A cheap ruler. A mid-priced tape measure. A shop-grade digital caliper. They all measure length. But if you ask them how long a bolt is, you get three different answers.
Why? Each tool has a limit of what it can see. That limit is called tolerance. Every trade, every lab, every engineer on earth has to know the tolerance of their tools - or they lose money and people die. Today you find out which tool you can trust.
What's the difference between accuracy and precision?
TED-Ed lesson by Matt Anticole; the cleanest 4-minute distinction between hitting the bullseye and hitting the same spot every time.
Foundations - Three Words
Accuracy = How close your measurement is to the TRUE value.
Precision = How repeatable your measurement is (same result every time).
Tolerance = The wiggle room you can live with before something breaks.
A sniper who hits 2 inches from the bullseye every shot = precise, not accurate.
A sniper who scatters all over but centers on the bullseye = accurate, not precise.
You want BOTH.
1Talk to your partner: name a tool in your life. What would happen if it were off by 10%?
Phase 2: Build
Woven notebook: keep your notebook open as you build. Record your hypothesis, every measurement and observation, and what surprised you. Your notebook is your lab record for this session.
Materials per pair: 1 ruler (cm/mm), 1 tape measure, 1 small object to measure (bolt, pen cap, washer, short pipe), notebook. Center caliper station: 3-4 digital calipers shared across the room (stagger - don't crowd). One pair at the caliper station at a time.
The Hypothesis
1Look at the object. Predict its length in millimeters. Write your prediction.
2Predict which tool will give the most precise answer. Why?
The Build - Triple Measurement
3Measure the object with the RULER. Read to the nearest mm. Record.
4Measure with the TAPE MEASURE. Record.
Beginner's Guide: How to Read a Metric Tape Measure
Two-minute walk-through of mm and cm markings so your tape reading matches your caliper reading in class.
5STATION ROTATION: while you wait for the caliper, predict what the caliper will read in mm for your object. Write the prediction so you can compare when you measure.
6When it's your turn at the caliper station: zero the caliper on closed jaws, then measure your object. The display reads to 0.01 mm. Record ALL decimal places - even the ones that look like noise.
How to Properly Use Calipers
Quick demo naming each caliper part and showing outside, inside, depth, and step measurements.
7Calculate percent difference between each pair of readings. Which two tools agree most?
8Now trade objects with another pair. Repeat. Did your rankings change?. Time-box: 10 min max.
9Rank your 3 tools from LEAST to MOST precise based on your readings. Write one sentence explaining why the ranking matches the price tag.
The tolerance ladder - Welding: plus/minus 1 mm. Machining: plus/minus 0.01 mm. Medication prep: plus/minus 0.01 mL. Each number = a career.
Launch the Tolerance Inspector
You ranked three real tools by precision. Now switch into the QA inspector seat: judge whether parts pass spec at four different tolerance levels - welding, auto, aerospace, medical. Same idea, different stakes.
10Tap 'Inspect Parts.' For each of 20 randomized parts, read the target dimension and tolerance, look at the measured value, and call PASS or FAIL. Watch your false-pass and false-fail counts at the end - false-pass is the one that gets people hurt.
11Switch to 'Tolerance Lab.' Load each preset (Bay Bridge gusset, Honda transmission, 737 landing gear bolt, pacemaker housing). Pull the tolerance slider tighter and watch the histogram show parts shifting from PASS to scrap. That's the math behind manufacturing cost.
12Finish with 'Quiz.' 8 scenario-based questions on tolerance, accuracy vs precision, the Rule of Ten, and Six Sigma. The explanations after each answer are the actual reasoning a Bay Area machinist uses on the shop floor.
You'll notice the same caliper that was 'precise enough' for a Honda part is rejected for a 737 part. Tolerance isn't about how good you are - it's about what the part is for.
Phase 3: Apply
Woven notebook: as the answers come into focus, write them down. Note where the real-world numbers matched your prediction and where they were different. The reveal only sticks if you put it in your own words.
Tolerance is a Career
Welder: plus/minus 1 mm on a structural joint. Off by more? The bridge fails.
Radiology Tech: plus/minus 2 degrees on positioning. Off by more? Missed tumor.
1Read above (1 min). Then continue.
CNC Machinist: plus/minus 0.01 mm on a jet engine part. Off by more? FAA audit.
HVAC Tech: plus/minus 1 psi on refrigerant charge. Off by more? System dies in 6 months.
Every one of these workers carries their own tools - because they trust their tools. That's the whole game.

Session 3: EMT Vitals Under Pressure
Pathway - EMT - Reading the Body in Real Time
0%
Phase 1: Spark
FACILITATOR PREP — Read 25 minutes before class.
Pre-stage: 4 BP-cuff stations around the room - each with BOTH a manual cuff + stethoscope AND an automatic cuff (students train on both and choose), plus pulse-ox + thermometer + log sheet. Lay out 35 Twizzlers in a bowl. Clear floor space for jumping jacks (2 ft per pair). Have ice water and a chair near the door in case anyone over-exerts.
Watch for: students with asthma or anxiety silently powering through the jumping jacks. Make the opt-out a recorder role, NOT a sideline. Stop the Twizzler activity immediately if any student feels dizzy.
Success looks like: every pair has a clean 4-point pulse graph (rest / post-exercise / 1 min / 3 min) and can name the shape of the recovery curve.
If it stalls: the Twizzler test never fails to land. Skip ahead to it if energy is low — the visceral 'I can't breathe' moment carries the rest of the hour.
Woven notebook: open your notebook now. Use it to capture every prediction, partner discussion, and question that comes up in this phase. Your notebook is the record of your thinking.
Welcome to Session 3! Today you will measure your own pulse, breathing, and oxygen levels, then read a patient's numbers like an EMT in the first 60 seconds of a call.
This session sits at the intersection of biology and decision-making: the four numbers that tell an EMT what to do next. Pulse, breathing, oxygen, blood pressure - every call starts there.
Bridge: Sessions 1 and 2 gave you the foundation skills - measurement and precision - that every career on this list demands. Starting today, every Wednesday is a different real career. Same lab rhythm, different pathway.
The Hook
You are an EMT. The radio crackles: '52-year-old male, chest pain, sweating, found at his desk.' You walk in. You have 60 seconds before the next decision.
One question matters first: what do his numbers say? Heart rate. Breathing. Oxygen. Pressure. If any one of them is off, you have a different call to make. Today you learn to read the body in real time - the same skill that puts you on a Bay Area ambulance team your first year out of high school.
Vital Signs For EMT Students: Fast and Easy
Quick walkthrough of the four numbers an EMT reads in the first 60 seconds of every call.
Last week you learned that tools measure reality. This week - YOU are the tool. Your hands, your eyes, a stopwatch. That's what an EMT has in the first 3 minutes.
Foundations - The EMT ABC
A = Airway (is the mouth/throat clear?)
B = Breathing (are they breathing? rate?)
C = Circulation (pulse? BP?)
Then the numbers:
- Pulse: 60-100 bpm normal
- Breathing: 12-20 per minute normal
- Blood Pressure: around 120/80 normal
- O2 Saturation: 95-100% normal
Shock = BP crashes, pulse races, skin cold. These are numbers you SEE with your hands.
1Talk to your partner: have you ever felt your heart race so hard you could hear it? What was happening?
Phase 2: Build
Woven notebook: keep your notebook open as you build. Record your hypothesis, every measurement and observation, and what surprised you. Your notebook is your lab record for this session.
Materials per pair: stopwatch (phone), graph paper, ruler, (optional) pulse oximeter, 1 Twizzler stick (or coffee stirrer / narrow straw) per student. SAFETY: students with asthma, anxiety, or any breathing condition - sit out as recorder. No one breathes through anything if they don't want to. Twizzlers are food-grade; do not reuse.
1Read above (1 min). Then continue.
Safety + consent: jumping jacks raise your heart rate fast - if you have asthma, a heart condition, or anything that makes hard exercise risky, stay seated and be the recorder. Pulse and breathing checks happen on the wrist (no neck pulses). If your partner doesn't want a hand on their wrist, take all readings on yourself - no pressure, no questions asked.
The Hypothesis
2Predict: after 30 jumping jacks, will your pulse double? Triple? Write a specific number.
3Predict: how long will it take to return to baseline?
The Build - Your Own Shock Test
4REST VITALS: Sit quietly for 1 minute. Partner finds your radial pulse (thumb side of wrist). Count beats for 15 seconds, multiply by 4. Record.
How to Obtain a Radial Pulse (EMTprep)
EMTprep is the actual NREMT prep company; shows thumb-side placement and the 15-second count method.
5Partner counts your breathing (1 breath = in + out) for 30 seconds, multiply by 2. Record. Do this WITHOUT telling them - people breathe weird when watched.
How to Count a Respiratory Rate (Without Your Patient Knowing)
Nurses keep their fingers on the wrist and watch the chest rise - this is the exact pro move you will copy.
6THE STRESS TEST: 30 jumping jacks. Go.
7IMMEDIATELY re-take pulse and breathing. Record.
8Wait 1 minute. Retake. Wait 2 more minutes. Retake. Record both.
9Switch roles. Repeat everything. Time-box: 10 min max.
10CHART IT: On graph paper, X-axis = time (0, immediately after, 1 min, 3 min). Y-axis = pulse. Plot. Draw the curve.
That curve you just drew? It is LITERALLY what an EMT sees on a monitor in an ambulance. The shape tells them if you are recovering - or crashing.
The Third Test - What Does Emphysema Feel Like?
Emphysema and COPD damage the alveoli (the air sacs in your lungs) AND narrow the airways. Air gets in - but it can't get out fast enough. Today's tube simulates the airway part. The alveolar damage is the rest of the picture, and we'll talk about what that adds.
11Predict: if you breathe ONLY through a Twizzler (or a narrow straw) for 60 seconds, what happens to your respiratory rate? Your pulse? Will it feel different than the post-exercise feeling?
12Pinch your nose closed. Place the Twizzler / straw between your lips as your only airway. Breathe normally through it for 60 seconds. Partner watches and times. STOP IMMEDIATELY if you feel dizzy or panicked.
13Right after the 60 seconds, partner takes your pulse (15 sec x 4) and respiratory rate (30 sec x 2). Record.
14Compare: how does this 'restricted airway' state compare to the post-jumping-jacks state from earlier? Same numbers? Different feel? Why?
Critical thinking: emphysema isn't just narrow tubes. The alveoli themselves break down, so the surface area for oxygen exchange shrinks. A patient with emphysema feels what you just felt - all day, every day. Walking to the mailbox feels like a sprint. This is why stopping smoking BEFORE damage starts is the #1 prevention message in every clinic.
15Group discussion: what would you say to a friend who started vaping this year? Use what you just felt to make the case - not facts, feeling.
Phase 3: Apply
Woven notebook: as the answers come into focus, write them down. Note where the real-world numbers matched your prediction and where they were different. The reveal only sticks if you put it in your own words.
How Real EMTs Read the Body in 60 Seconds
Thermoregulation in Humans
Three-minute refresher on the negative-feedback loop the app's interpreter reads back to you.
When an EMT walks up to a patient, they already have answers before they touch them.
Eye-level scan (5 seconds): skin color, chest rising, alert/unconscious.
Hands on the wrist (10 seconds): pulse rate and quality.
Hands on the chest / pulse ox on finger (30 seconds): breathing rate, O2 sat.
BP cuff (45 seconds): the number that tells them if the patient is crashing.
3 minutes later: they know if this is a cardiac event, a stroke, a diabetic emergency, or shock - all from the numbers.
That is a skill anyone can learn. You already started.
Two tools, two videos. Real EMTs learn BP on a MANUAL cuff (pump it, listen through a stethoscope for the heartbeat sounds) AND an AUTOMATIC cuff (press Start, it reads for you). Learn both below, then take a reading with each at your station, compare how closely they agree (within 5 mmHg is excellent), and choose the one you trust. Both cuffs are at every station today.

Session 4: The Order of the Draw
Pathway - Phlebotomy - Sequence is Everything
0%
Phase 1: Spark
FACILITATOR PREP — Read 30 minutes before class.
Pre-stage: cut pool noodles into 4-inch arm sections (2 minutes per section with a serrated knife). Set up 2 phlebotomy stations: noodle arm + tube mock set + simulated blood + tourniquet + glove box. Lay tarp or paper under each station — the simulated blood stains.
Watch for: students mixing up the order of draw (yellow / light blue / red / gold / green / lavender / gray). The mnemonic is 'Stop Light Red Stay Green Lit' — write it on the board.
Success looks like: every student can recite the order from memory by the end of Build, and the tubes are filled to the line (not over).
If it stalls: the lavender-tube cross-contamination video on YouTube is 90 seconds and lands the 'why this matters' instantly.
Woven notebook: open your notebook now. Use it to capture every prediction, partner discussion, and question that comes up in this phase. Your notebook is the record of your thinking.
Welcome to Session 4! Today you will draw a 'patient's' blood across a row of color-coded tubes and find out exactly how the order changes the answer the lab gets back.
This session sits at the intersection of chemistry and procedure: the order matters because the additive in the previous tube can ruin the next one's results. One drop, wrong patient, wrong call.
The Hook
A 5-year-old comes into the ER with a fast heart rate. The phlebotomist draws the blood. The lab returns: potassium 6.4 - dangerously high - and the doctor orders an emergency cardiac workup.
Problem: the potassium was wrong. The phlebotomist drew the EDTA tube before the green tube. EDTA contains potassium. A drop carried over and contaminated the chemistry sample. Same patient, same blood, wrong answer - because the order was wrong.
You are being trained to be the person who knows the order cold.
Order of Draw Mnemonic
RegisteredNurseRN's mnemonic for the tube-color sequence that prevents lab-result errors.
Blood isn't blood. Once drawn, every test needs a different chemical preservative. Mix them up and the whole sample is contaminated. That's why order matters.
Foundations - Tubes Aren't Just Tubes
Each blood collection tube has a colored cap. The color tells you the ADDITIVE inside.
- Yellow = sterile (blood cultures - first, to stay pure)
- Light Blue = citrate (coagulation tests - clotting)
- Red = no additive or gel (serum tests)
- Green = heparin (chemistry panels)
- Lavender / Purple = EDTA (CBC - complete blood count)
- Gray = fluoride (glucose / alcohol)
If you draw in the wrong order, the earlier tube's chemical contaminates the next one. That's carryover.
1Where in your life does the ORDER of steps matter? Name one.
Phase 2: Build
Woven notebook: keep your notebook open as you build. Record your hypothesis, every measurement and observation, and what surprised you. Your notebook is your lab record for this session.
Materials per group: 6 small cups labeled Yellow, Blue, Red, Green, Purple, Gray; food coloring to match colors; water; 1 pipette or small spoon per group; 1 coffee filter cut into strips; markers
1Read above (1 min). Then continue.
Lab safety: in a real phlebotomy draw, every needle is a sharps biohazard - count in, count out, dispose in the red sharps container. We're using food coloring and water today (no sharps), but treat the practice the same way: clean station, no eating or drinking at the lab table, wash hands after handling pipettes. Wear safety glasses if your group has them.
The Hypothesis
2Predict: if you draw blood in this order - PURPLE first, then BLUE - what will the BLUE sample look like?
The Build - Carryover in Living Color
3Prep the 'tubes': fill each colored cup with water tinted to match its label. These represent the additives inside each tube.
4WRONG ORDER TEST: Use the pipette to take a drop from PURPLE. Put that drop into the BLUE cup. Stir gently. Take a drop from the now-contaminated BLUE and put it on a coffee filter strip. Watch what color appears.
5RIGHT ORDER TEST: Start over with clean water. Take from BLUE first (nothing to contaminate it). Put on a new coffee filter strip. Compare colors.
6Now simulate the FULL real order: Yellow to Blue to Red to Green to Purple to Gray. Draw one drop from each in that order, each onto a new filter strip. Line them up. Do you see creep between samples?
7Try the WRONG order (reverse or random). Compare the two filter strip sets side by side.
8Flip the filter strips over. Can you still see the color creep through to the back? That's the contamination a lab would reject.
9Talk with your partner: if this were a real blood panel, which tube would give a FALSE reading, and which patient result might change because of it?
Phlebotomy Skills - Order of Draw
Certified phlebotomy instructor runs the full seven-tube sequence on a training arm; this is what your filter-strip simulation was modeling.
That creep you saw on the filter strips? That is EXACTLY what happens at the molecular level in a real blood draw. The order of draw is how phlebotomists prevent it.
Launch the Order of Draw Simulator
Coffee filter strips showed you contamination color-creep. Now run the same physics on real lab values: see exactly how much a wrong-order draw skews a patient's calcium, potassium, or PT/INR - and what the doctor would do with the bad number.
10Tap 'Draw the Tubes.' Load each patient case (Mr. Reyes ER chest pain, Ms. Chen prenatal, Mr. Williams sepsis at UCSF Parnassus). Tap-to-swap the colored tubes into correct CLSI order, then 'Simulate the Draw.' If you got it wrong, the app shows you exactly which lab values would read falsely abnormal and what the ER team would do with that bad data.
11Switch to 'Carryover Lab.' Pick any 'from' tube and any 'to' tube. See the real chemistry effect side-by-side - EDTA carryover into a Gold tube literally drops the calcium reading from 9.8 to 7.2. That's a fake hypocalcemia, and the patient gets unnecessary calcium infused.
12Finish with 'Speed Quiz.' 8 rounds of rapid-fire ordering. You're given 4-6 random tubes and have to tap them into correct CLSI order under time pressure. This is muscle memory - real phlebotomists draw 30+ patients a day without looking at a chart.
Watch what happens to potassium when EDTA contaminates a Green tube. EDTA is potassium ethylenediaminetetraacetate - so a tiny drop spikes the K+ reading. Same patient, same blood, wrong order, different doctor's call.
Phase 3: Apply
Woven notebook: as the answers come into focus, write them down. Note where the real-world numbers matched your prediction and where they were different. The reveal only sticks if you put it in your own words.
The Real Order of Draw (CLSI Standard)
Yellow (blood culture) → Light Blue (coag) → Red (serum) → Gold/Tiger (SST) → Green (heparin) → Lavender (EDTA) → Gray (fluoride)
Mnemonic: Your Best Records Should Get Lots of Glances.
Every phlebotomist on earth knows this. It's 7 colors. You just simulated it.
The person who draws blood correctly is the reason every doctor's diagnosis is real. Without them, the whole system lies to itself.

Session 5: The Body's Thermostat
Pathway - CNA - Homeostasis in Real Time
0%
Phase 1: Spark
FACILITATOR PREP — Read 20 minutes before class.
Pre-stage: 4 IR thermometer stations, 6 ice packs in the freezer the morning of (cold from the fridge isn't cold enough), 6 heat packs warmed in microwave 30 seconds (NOT hot — facilitator tests first). Pre-print homeostasis data sheets.
Watch for: students leaving ice packs on skin past 10 minutes (skin burn risk) and pointing IR thermometers at reflective surfaces (false readings).
Success looks like: every student's body-temp graph shows the negative-feedback dip-and-recover pattern, and at least one pair spots that hands return to baseline faster than feet.
If it stalls: rotate roles — let the student who's been on the thermometer take a turn as the data recorder. The numbers change fast, recording is its own engagement.
Woven notebook: open your notebook now. Use it to capture every prediction, partner discussion, and question that comes up in this phase. Your notebook is the record of your thinking.
Welcome to Session 5! Today you will plunge your hand into ice water, watch your pulse drop, and trace exactly how your body fights to keep its core temperature within a tenth of a degree.
This session sits at the intersection of biology and patient care: homeostasis - the way the body holds itself steady. CNAs catch trouble first because they know what 'steady' looks like for each patient.
The Hook
A 78-year-old patient at a skilled nursing facility starts shivering, then stops. Her temperature reads 102.4F. Her CNA, on a routine round, notes it and walks straight to the nurse.
Within 30 minutes she is on antibiotics for early sepsis. The CNA caught it because she'd taken that patient's vitals 40 times. She knew what 'normal' looked like for this woman, and what 'off' looked like.
Today you learn the body's thermostat from the inside - and why every CNA on the floor is the early-warning system.
Thermoregulation in Humans
Three-minute animation of the negative-feedback loop your skin and brain run every time the temperature shifts.
Your body is a thermostat that won't quit. 98.6 F is where you live. Two degrees in either direction and your brain starts to fail.
Foundations - Negative Feedback Loops
A set-point is a target the body wants to hit. A negative feedback loop is how it gets back.
Example: body temp rises (hot day). Sensors in the brain detect it. Response: sweating (cools) + blood vessels dilate (heat escapes skin) + behavior (find shade). Temperature drops back to set-point.
Opposite: body temp drops. Shivering kicks in (muscles make heat). Blood vessels constrict (keep heat in core). Behavior (find heat).
Your body is doing this RIGHT NOW - 24/7, unconscious, all day.
1Name 3 'set-points' you have in your own life - things you fight to keep steady.
Phase 2: Build
Woven notebook: keep your notebook open as you build. Record your hypothesis, every measurement and observation, and what surprised you. Your notebook is your lab record for this session.
Today's vital is HEART RATE under cold stress - and the surprise is that not everyone's pulse goes the same direction. Your nervous system carries an ancient inheritance from when humans dove for food: the MAMMALIAN DIVING REFLEX. We're going to find out whose body still remembers.
1Read above (1 min). Then continue.
Safety + consent: ice water on a hand for 60 seconds is uncomfortable, not dangerous - but if you have Raynaud's, circulation issues, or any reason cold hurts you, opt out and be the recorder for both rounds. No one needs to explain why they're sitting out. Pulse readings happen on the wrist (radial), not the neck. If your partner says stop before the 60 seconds is up, you stop immediately.
The Hypothesis
2Predict: when you put one hand in ice water for 60 seconds, will your heart rate go UP, DOWN, or stay the same? Write a number for the change (e.g., +10 bpm or -8 bpm).
3Predict: which would slow your heart rate MORE - hand in ice water, or face submerged in ice water? Why?
The Build - Diving Reflex Test
4BASELINE: sit quietly for 1 minute. Partner takes your wrist pulse (radial pulse) for a FULL 60 seconds (no shortcut math today - we want the real rhythm). Record.
How to Obtain a Radial Pulse (EMTprep)
60-second technique for finding the wrist pulse (radial pulse). Two fingers on the thumb-side of the wrist, count the beats. Same skill EMTs and CNAs use every shift.
5Fill bowl with ice water. Measure water temp - it should be near 0 C (32 F). Record.
6Submerge ONE hand up to the wrist. Start the timer. Partner finds your pulse on your OTHER wrist while your test hand is still in the water. Begin counting at 30 seconds in - count for 30 seconds. Multiply by 2. Record this as 'cold-stress pulse.'
7Pull out at 60 seconds. Immediately partner takes a third pulse reading - 30 seconds, x 2. Record as 'recovery pulse.' Note any change in skin color (paler? redder?).
8Switch roles. Repeat. (If anyone is opting out, they stay the recorder for both rounds.). Time-box: 10 min max.
9Calculate: cold-stress pulse minus baseline pulse. Was your number POSITIVE (heart rate went up - sympathetic / fight-or-flight) or NEGATIVE (heart rate went down - parasympathetic / diving reflex)?
10Class chart: every student writes their delta on the whiteboard (e.g., +6, -4, +12, -2). Sort fastest-increase to fastest-decrease. Where do most people land? Are there outliers?
Why the split: the mammalian diving reflex is real and ancient - cold water on the face triggers bradycardia (slower heart) and shunts blood to the core to conserve oxygen. It's strongest with FACE submersion. Hand-only is weaker, so most students show a stress response (rate UP). The students whose rate dropped have a stronger diving reflex - and free divers, surfers, and competitive swimmers train this on purpose. Both responses are normal homeostasis.
11Discussion: what does this tell you about how a CNA needs to read vital signs? Two patients with the same cold exposure can show OPPOSITE pulse responses. Trust the numbers, not the assumption.
12Open the Vital Signs Interpreter. Enter the BEFORE-plunge pulse you measured, then enter the AFTER pulse. The app classifies your delta (Bradycardia, Normal, Tachycardia) the way a CNA would interpret it for the nurse on duty.
13Switch to the 'Neuro Check' tab. Enter realistic vital-sign cards for a 78-year-old with chills - temperature, pulse, BP, SpO2 - and read what the app flags. This is exactly the call a CNA makes 10 times a shift.
Phase 3: Apply
Woven notebook: as the answers come into focus, write them down. Note where the real-world numbers matched your prediction and where they were different. The reveal only sticks if you put it in your own words.
What a CNA Actually Does
Every 4 hours in a hospital or nursing home, a CNA:
- Takes vital signs (pulse, BP, temp, O2, resp rate)
- Helps patients eat, bathe, walk
- NOTICES the subtle changes - skin color, slurred speech, confusion, shivering
- Reports to the nurse
Because the CNA is the one actually TOUCHING the patient 8 hours a day, they catch deterioration FIRST. A great CNA has saved countless lives by saying: 'Something is different today.'
CNA is also the #1 ladder to becoming an LVN, then RN, then NP or BSN. Nearly every nurse in America started with a CNA cert.

Session 6: EKG - The Signature of the Heart
Pathway - Medical Assistant - Reading Electrical Signals
0%
Phase 1: Spark
FACILITATOR PREP — Read 25 minutes before class.
Pre-stage: 1 mannequin torso + heart model at a demo station (facilitator-led during Spark). Print 70 EKG rhythm strips (2 per student) and pre-shuffle them so partners don't have the same rhythm. Open the EKG Reader app in a browser tab on every laptop.
Watch for: students applying electrodes over a shirt (no contact, false reading) and missing the difference between V-tach and V-fib on the practice strips — the visual difference is the regularity, NOT the amplitude.
Success looks like: every pair correctly identifies sinus rhythm, tachycardia, and at least one lethal rhythm (V-fib or asystole) from a printed strip.
If it stalls: the 'is this person dying?' framing works — for any strip, ask 'if you saw this on the monitor, would you call a code?' Forces a yes/no commitment.
Woven notebook: open your notebook now. Use it to capture every prediction, partner discussion, and question that comes up in this phase. Your notebook is the record of your thinking.
Welcome to Session 6! Today you will read real EKG strips, label the P, QRS, and T waves, and call out the rhythm like a medical assistant in a Kaiser cardiology clinic.
This session sits at the intersection of electricity and the human heart: every heartbeat is an electrical event you can trace on paper. Read the wave, you read the heart.
The Hook
A 60-year-old walks into urgent care. Chest tightness, sweating, nausea. The medical assistant runs an EKG before the doctor even arrives.
The MA looks at the strip and sees ST-segment elevation in the inferior leads - the bottom of the heart (the bottom of the heart (the inferior wall)) is starving for oxygen. She flags it as a probable heart attack and the doctor activates the cath lab. The patient is in surgery within 90 minutes.
That MA caught a heart attack with two skills: place the leads, read the wave. Today you learn both.
EKG Basics in Under 5 Minutes
Khan Academy walks through the P, QRS, and T waves you'll be labeling today.
Your heart runs on electricity. Every beat sends a pulse through the muscle. An EKG is just a drawing of that pulse on paper.
Foundations - P, QRS, T
Three bumps in each heartbeat:
- P wave = atria (top chambers) fire
- QRS complex = ventricles (bottom chambers) fire (THE BIG SPIKE)
- T wave = recovery
The Math:
bpm = 60 / (time between R peaks in seconds)
Example: R peaks are 1 second apart.
bpm = 60 / 1 = 60 bpm. Normal.
R peaks are 0.6 seconds apart.
bpm = 60 / 0.6 = 100 bpm. Fast.
1Look at your own wrist pulse. If you count 15 beats in 10 seconds, what's your bpm?
Phase 2: Build
Woven notebook: keep your notebook open as you build. Record your hypothesis, every measurement and observation, and what surprised you. Your notebook is your lab record for this session.
Materials per student: graph paper (1 mm grid), ruler, pencil, calculator (phone OK)
The Hypothesis
1Predict: what does a fast heart look like on paper compared to a slow one? Sketch your prediction.
The Build - Draw Three EKGs
2Paper speed rule: standard EKG paper runs at 25 mm/sec, so 1 small square (1 mm) = 0.04 seconds, and 5 small squares (one big square) = 0.20 seconds. The TIME between R peaks tells you the heart rate; the SHAPE between them tells you what kind of beat it is.
How to Count Heart Rate on an EKG Strip - 6 Second Rule (RegisteredNurseRN)
Five-minute walkthrough of the small-square and 6-second counting methods every cardiology MA learns Week 1.
3EKG #1 - NORMAL 60 bpm: R peaks should be 1 second apart = 25 small squares. Draw 3 heartbeats. Label P, QRS, T on each.
4EKG #2 - TACHYCARDIA 100 bpm: R peaks 0.6 seconds apart = 15 small squares. Draw 3 heartbeats.
5EKG #3 - DANGER 180 bpm: R peaks 0.33 seconds apart = about 8 small squares. Draw 3 heartbeats.
EKG #4 - Atrial Fibrillation (AFib)
AFib is the most common dangerous rhythm a medical assistant or EMT will see. It is NOT defined by speed - it's defined by IRREGULARITY. The atria quiver instead of contracting. Two giveaways on paper: (1) R-R intervals are irregularly irregular (no pattern), (2) P waves are missing or replaced by a jittery baseline.
6Draw 5 R peaks across your paper with R-R distances of: 18, 12, 22, 9, 16 small squares (totally irregular). Skip the P wave - draw a small jittery wiggle on the baseline instead. That's AFib.
7Now open the EKG Reader app. Switch between Normal, Tachycardia, Bradycardia, and Atrial Fibrillation. Watch the rhythm draw in real time. Compare to your three hand-drawn strips. Which one is hardest to read? Why?
Why AFib matters: the quivering atria let blood pool. Pooled blood clots. The clot can travel to the brain and cause a stroke. Untreated AFib raises stroke risk 5x. Catching AFib on a routine EKG - in a clinic, in a CNA's vitals check, on an Apple Watch - has prevented millions of strokes. The reader is sometimes a machine, but the decision to ACT on what the machine said is human.
8Measure the P-R interval on your first EKG (from start of P to start of QRS). Convert small squares to seconds. Normal = 0.12 to 0.20 seconds.
9Trade EKGs with a partner. Calculate their bpm just from looking at R-R spacing.
10Mark any of your 3 EKGs where the P-R interval looks LONGER than 0.20 seconds (5 small squares). In a real clinic, that flag triggers a callback to the cardiologist.
You just did exactly what an MA does every morning in a cardiology office - measure intervals, calculate rate, flag anything weird.
Phase 3: Apply
Woven notebook: as the answers come into focus, write them down. Note where the real-world numbers matched your prediction and where they were different. The reveal only sticks if you put it in your own words.
What an MA Reads in 30 Seconds
MA looks at the strip and checks 4 things:
1. Rate (bpm) - is it 60-100?
2. Rhythm - are R peaks evenly spaced?
3. P waves - is there ONE before every QRS?
4. QRS shape - is it narrow (normal) or wide (problem)?
In 30 seconds the MA can flag: atrial fibrillation, heart block, tachycardia, bradycardia. Doctor walks in knowing already. That is trust.
Every cardiology office, urgent care, and emergency room in the Bay Area needs MAs who can do this.

Session 7: The Inverse Square Law
Pathway - Radiology Tech - Distance and Safety
0%
Phase 1: Spark
FACILITATOR PREP — Read 20 minutes before class.
Pre-stage: 4 light-meter stations, each with a phone-flashlight or small LED, a tape measure, and the inverse-square data sheet. Dim the room lights for the measurement portion. Confirm the rad-tech career video loads on the projector before class.
Watch for: students measuring distance to the LED's case rather than the bulb (introduces a 1-cm error that dominates short-distance readings) and conflating brightness drop with linear distance.
Success looks like: every pair plots a 1/r² curve that hits within 10% of theoretical at three distances, and can name one place rad techs use this rule (lead-apron distance, room shielding).
If it stalls: ask 'why does the dentist leave the room when they X-ray your teeth?' That single question recovers the entire 'inverse square = your job depends on it' frame.
Woven notebook: open your notebook now. Use it to capture every prediction, partner discussion, and question that comes up in this phase. Your notebook is the record of your thinking.
Welcome to Session 7! Today you will measure how radiation intensity drops as you step back from the source, then plan a real CT-room safety setup using only distance and shielding.
This session sits at the intersection of geometry and patient care: the inverse square law. A small step back, a huge drop in dose. The same math saves the tech and the patient every shift.
The Hook
A radiology tech at UCSF runs 30 CT scans on a busy Monday. By the end of the day, with no shielding, she would have absorbed enough radiation to harm her. With shielding and distance? Less than a chest x-ray.
The difference is the inverse square law - radiation falls off with the square of the distance. Double your distance, drop your dose by 4x. Triple it, by 9x.
Today you learn the math that protects every rad tech in the Bay Area - and the patients in their care.
Inverse Square Law: Explained!
Three minutes of geometry explaining why every step back from a radiation source cuts your exposure by a factor of four.
A light at 1 meter looks bright. At 2 meters it looks 1/4 as bright. Not 1/2. A QUARTER. This is one of the most important laws in all of physics - and it determines why rad techs stand where they stand.
Foundations - The Formula
Intensity proportional to 1 / distance squared.
Double distance = quarter intensity.
Triple distance = one-ninth intensity.
Halve distance = four times intensity.
This applies to light, sound, radio waves, X-rays, and radiation in general. Nature loves this pattern.
1Predict: if a flashlight reads 100 lux at 1 meter, what will it read at 2 meters?
Phase 2: Build
Woven notebook: keep your notebook open as you build. Record your hypothesis, every measurement and observation, and what surprised you. Your notebook is your lab record for this session.
Materials per pair: 1 smartphone with Lux Light Meter app installed (free), 1 flashlight (phone flashlight is OK), tape measure, dark room or corner, graph paper
1Read above (1 min). Then continue.
Safety: the flashlight stand-in is harmless, but in a real X-ray room the rule is inverse-square PLUS lead shielding PLUS time limits. The three-rule combination is what keeps rad techs at dose limits below 50 mSv/year.
The Hypothesis
2Based on the inverse square law, predict the lux reading at each distance. 1 m = 100 lux (baseline). 2 m = ?, 3 m = ?, 4 m = ?
The Build - Inverse Square Test
3Open Lux Light Meter app. Find a dim corner.
4Hold the flashlight at exactly 1 m from the phone sensor. Record lux reading. This is your baseline.
Measuring Light - Inverse Square Law (AYVAEducational)
Classroom demo of exactly our lab: flashlight, phone meter, distance doubled, intensity quartered.
5Move flashlight to 2 m. Record lux.
6Move to 3 m. Record.
7Move to 4 m. Record.
8Calculate predicted values: baseline divided by 4, by 9, by 16. Compare to actual readings.
9Chart it: distance on X-axis, lux on Y-axis. Draw the curve.
10How close was your prediction? Within 20%? Within 50%? Why the difference? (Ambient light, angle, sensor calibration.)
The curve you just drew is the SAME curve radiation follows around an X-ray machine. That's why rad techs stand 6 feet behind the lead shield - not 3 - to drop their exposure by 75%.
Launch the Radiation Distance Visualizer
You measured lux at 1, 2, 3, 4 m and saw the inverse square law with a flashlight. Same math, X-ray source, life stakes. The visualizer shows you the radiation field shrinking as you step back, plus the shields a real rad tech uses every day.
11Tap 'Move Around the Source.' Drag the rad tech's position closer and farther from the X-ray source. Watch the radiation field on the SVG visibly shrink. The dose readout updates live for both the tech and the nurse fixed at 1 m. Then start the exposure timer and see how fast you'd hit the 50 mSv annual limit at each distance.
12Switch to 'Shield Lab.' Toggle on lead apron, lead glass, mobile shield, thyroid collar - one at a time, then stacked. Load each scenario (portable chest X-ray, fluoroscopy GI, pediatric cath, CT control room). The ALARA score grades your shield combination against what a working rad tech actually picks.
13Finish with 'Quiz.' 8 questions on inverse-square calculations, ALARA, the 50 mSv NRC limit, and which shield to use for which procedure. The Foothill / CCSF / Skyline rad tech program info is in the answer explanations.
Notice that doubling distance from 1 m to 2 m drops your dose to ONE FOURTH, not one half. Distance is the cheapest shield in radiology. Lead aprons help with scatter; distance helps with everything.
Phase 3: Apply
Woven notebook: as the answers come into focus, write them down. Note where the real-world numbers matched your prediction and where they were different. The reveal only sticks if you put it in your own words.
Why Rad Techs Stand Where They Stand
In a real radiology room:
- The X-ray tube is positioned over the patient.
- The rad tech moves BEHIND a lead shield before pressing the button.
- The shield is usually 6 feet away.
- The tech wears a dosimeter badge that tracks their exposure for the year.
Why 6 feet, not 3?
At 3 feet, exposure = X.
At 6 feet, exposure = X/4.
Over a 20-year career, that's the difference between healthy retirement and cancer risk.
The math isn't abstract. It's the shield.

Session 8: HVAC - The Refrigerant Dance
Pathway - HVAC - Phase Change and Heat Transfer
0%
Phase 1: Spark
FACILITATOR PREP — Read 25 minutes before class.
Pre-stage: ice in cooler (delivered day-of). 6 thermometers + 6 cups + salt cartons on the back table. 3 wood/metal pairs at demo stations. Open the Refrigerant Cycle Animator on the projector before students walk in — the animated cycle is the hook.
Watch for: students adding salt BEFORE measuring baseline temperature (skews the whole experiment), and over-stirring (introduces room-air heat). Stir twice, wait 30 seconds, read.
Success looks like: every pair's salt-ice cup hits -8 °C or colder, and they can connect the cup-going-cold to refrigerant absorbing heat from a house's air.
If it stalls: the wood-vs-metal tongue-on-flagpole story always lands. Ask 'why does the metal feel colder if they're the same temp?' before doing the ice-cube test — the answer is the test.
Woven notebook: open your notebook now. Use it to capture every prediction, partner discussion, and question that comes up in this phase. Your notebook is the record of your thinking.
Welcome to Session 8! Today you will trace the refrigerant cycle through compressor, condenser, evaporator, and expansion valve, and diagnose three real HVAC failures using only readings and pressure gauges.
This session sits at the intersection of phase change and money: when refrigerant boils, it pulls heat. Master that loop and you master heating, cooling, and almost every paid trade in California.
The Hook
A Bay Area heat-pump installer rolls up to a customer with no AC. 90F outside. Customer is sweating. Tech connects a manifold gauge, reads the pressures, looks at the suction line. Frosted. Diagnosis in three minutes: low refrigerant + restricted expansion valve. Repair: a few hundred dollars on the right diagnosis.
The tech who can read the cycle gets the call. The one who can't - or who guesses - replaces the wrong part and loses the customer. Today you learn the loop.
HVAC Refrigeration Cycle Explained
Compressor, condenser, evaporator, expansion valve - the four-stop loop you'll trace in today's lab.
A refrigerator doesn't make cold. It PUMPS heat out. Your AC doesn't make cold - it pumps heat out of your house. This is the whole game of HVAC.
Foundations - The 4-Step Cycle
1. COMPRESS the refrigerant (gas) - it gets hot.
2. CONDENSE it outside (gas becomes liquid) - heat released outside.
3. EXPAND the liquid - it gets COLD.
4. EVAPORATE it inside (liquid becomes gas) - absorbs heat from your house.
Back to step 1. Repeat forever.
Phase change (liquid to gas, gas to liquid) is where the energy moves. It's the same reason sweat cools you down - water evaporating off your skin absorbs heat.
1Where else in your life does 'phase change' happen? Think big - ice to water, water to steam, but also: moments where things SHIFT?
Phase 2: Build
Woven notebook: keep your notebook open as you build. Record your hypothesis, every measurement and observation, and what surprised you. Your notebook is your lab record for this session.
Materials per pair: 2 clear cups, ice cubes, table salt (2 Tbsp), room-temp water, kitchen/lab thermometer, stopwatch, notebook, graph paper. Plus per pair: 2 identical ice cubes, 1 small wood block (about 4x4 in), 1 metal plate or aluminum/cast-iron pan (at room temp). Both blocks need to be at room temperature - check with the thermometer before starting.
1Read above (1 min). Then continue.
Safety: handle ice briefly (cold burn risk if held too long). Keep the saltwater cups clear of bags and electronics. Wipe any spills before the next pair rotates in.
The Hypothesis
2Predict: if you add salt to ice water, will the temperature go UP, DOWN, or stay the same? By how much?
The Build - The Salt-Ice Phase Change
3Fill cup 1 with ice. Add a small amount of water (just enough to cover the ice). Measure baseline temperature. Record (usually 0 C / 32 F).
4Add 2 tablespoons of salt. Stir.
5Start timer. Record temperature every 30 seconds for 5 minutes.
Making YOU the Scientist: Freezing Point Depression and Phase Changes (Step by Step Science)
Classroom demo of salt plus ice dropping below 0 C. Same setup, same math, same phase-change principle that runs every AC on earth.
6Optional bonus: fill cup 2 with room-temp water and nest it in cup 1. Watch cup 2's water start to cool. That's heat moving from cup 2 into cup 1 - EXACTLY like a refrigerator moves heat from your food into the refrigerant.
7Chart it: time on X-axis, temperature on Y-axis. How cold did cup 1 get? (Should hit about -10 C or 14 F.)
8Touch the outside of cup 1 with your finger (safe, just cold). Notice the condensation forming on the outside. That water came from the AIR, not the cup. Explain why.
9Predict: if you doubled the amount of salt, would the temperature drop FURTHER, or hit a floor? Then test it if time allows.
The salt disrupts the ice crystal - the ice has to ABSORB heat from its surroundings to melt. That absorbed heat = cold environment. This is the same phase-change principle HVAC uses. Refrigerant absorbs heat when it evaporates. You just watched HVAC happen in a cup.
The Second Test - Why Did His Tongue Stick?
Same temperature, different surface, very different result. Wood and metal can both be at -10 F outside, but only ONE will stick to your tongue. The reason is THERMAL CONDUCTIVITY - how fast a material moves heat. Metal is roughly 300x better at conducting heat than wood. On a flagpole, your warm wet tongue loses heat to the metal so fast the saliva freezes instantly. On a wooden post, the heat stays where it is. This is the same physics that decides why HVAC systems use copper coils, not pine.
10Predict: if you put identical ice cubes on a wood block and a metal plate (both at room temp), which melts faster? By how many minutes?
11Place one ice cube on the wood block, one on the metal. Start the timer. Touch each block with your hand - they FEEL like different temperatures even though they're both room temp. Why? (Answer: the metal is pulling heat OUT of your hand fast.)
12Time both ice cubes until they fully melt. Record both times. Calculate the ratio: metal time vs wood time.
13Connect to HVAC: refrigerant lines are made of COPPER for the same reason. The whole job of an HVAC system is to move heat - and copper moves heat almost as fast as a flagpole takes a tongue. Insulation (fiberglass, foam) is the opposite extreme - it traps heat. An HVAC tech designs systems by picking which surface needs to conduct (coils) vs which needs to insulate (ducts and walls).
Launch the Refrigerant Cycle Animator
Salt-ice showed you phase change. Wood vs metal showed you heat transfer. The refrigerant cycle is both - all happening 24/7 in the AC unit outside your house. Watch it move.
Basic Refrigeration Cycle
Color-coded animation of the four-stop loop - matches the lights and pressures in the app.
14Tap 'Watch the Cycle.' Animated dots flow through the loop - blue for cold liquid, red for hot gas. Click the compressor, condenser, expansion valve, and evaporator one at a time to see what's happening to the refrigerant at each stage (phase, pressure, real R-410A pressure readings on a 95 F day). Toggle between cooling and heating mode to see the same hardware run the cycle backwards.
15Switch to 'Diagnose the System.' Real service-call symptoms: warm air blowing, short-cycling compressor, frosted suction line, swollen capacitor, R-22 legacy unit. Pick the failing component based on the pressure / temp readings. The ones a tech sees on every day-one ride-along.
16Finish with 'EPA 608 Quiz.' 8 questions modeled on the real EPA Section 608 Universal certification - the entry-level cert every Bay Area HVAC tech needs to legally handle refrigerants. Laney College gets students through 608 in 8 weeks.
Watch the dots change color as they cross the expansion valve - that's a sudden pressure drop converting warm liquid to cold liquid. That tiny brass component is doing what the salt did in your cup.
Phase 3: Apply
Woven notebook: as the answers come into focus, write them down. Note where the real-world numbers matched your prediction and where they were different. The reveal only sticks if you put it in your own words.
Phase Change Runs the World
Every air conditioner on earth. Every fridge. Every heat pump. Every freezer truck. Every commercial cooling system.
All run on the same 4-step cycle you just watched in your cup.
An HVAC tech who knows this cycle can:
- Charge a refrigerant line correctly
- Diagnose why an AC isn't cooling (usually leaky refrigerant)
- Install a heat pump (the green-retrofit industry is exploding in California)
- Certify to EPA 608 standards - required by federal law
Bay Area heat-pump demand is doubling year over year due to California electrification mandates. This trade is not slowing down.

Session 9: Chasing the Sun
Pathway - Solar / Renewable Energy - Angle and Irradiance
0%
Phase 1: Spark
FACILITATOR PREP — Read 25 minutes before class.
Pre-stage: 5 solar-panel stations (panel + multimeter + alligator leads + protractor). Set up a desk lamp at each station OR work near windows on a sunny day. Test that every multimeter reads volts on the DC scale before class.
Watch for: students wiring the multimeter in series instead of across the panel terminals (zero reading, looks broken). Demo the correct hookup once at the front before pairs start.
Success looks like: every pair finds that the panel peaks at a specific tilt angle for the room's light source, plots the curve, and can name why solar installers care about latitude.
If it stalls: the 'why are roofs in Arizona different from roofs in Seattle' framing works. Pull up a satellite view of both cities and ask students to spot the difference in panel angles.
Woven notebook: open your notebook now. Use it to capture every prediction, partner discussion, and question that comes up in this phase. Your notebook is the record of your thinking.
Welcome to Session 9! Today you will tilt a model panel through every angle of the sun, log the irradiance reading, and find the angle that pulls the most kilowatt-hours from a Bay Area roof.
This session sits at the intersection of geometry and the energy grid: every degree of panel tilt changes the watts you harvest. Solar installers live and die by that number.
The Hook
Two identical solar arrays. Same panels, same inverter, same roof. One produces 8,200 kWh/year. The other produces 6,400 kWh/year.
The difference: a 12-degree tilt error on installation day. That mistake cost the homeowner thousands per year for the next 25 years.
The installer who can dial in the angle keeps the customer. The one who can't gets the callback - or the lawsuit. Today you become the one who gets it right.
Tilt and Azimuth for Solar Panels
Why every degree of panel tilt changes the kilowatt-hours that hit your meter.
A solar panel is like a sail. Angle it wrong, you catch less wind. Angle it right, you catch everything. The math of the sun = money.
Foundations - Angle, Not Just Area
Two key numbers for any solar panel:
- AZIMUTH = which compass direction it faces. South = best in California.
- ALTITUDE (tilt) = how steep it is. For Bay Area: 30-35 degrees is optimal.
The math:
Kilowatts output proportional to cos(angle between sun ray and panel surface)
When sun hits panel perpendicular (0 degrees): 100% output.
At 45 degrees off: about 70% output.
At 60 degrees off: 50% output.
At 90 degrees off (sun grazing parallel): 0%.
1Look around the room. Which window would get the most sun in summer? Why?
Phase 2: Build
Woven notebook: keep your notebook open as you build. Record your hypothesis, every measurement and observation, and what surprised you. Your notebook is your lab record for this session.
Materials per pair: 1 mini solar panel (2W or larger), 1 multimeter, 1 bright flashlight, protractor, cardboard (to angle the panel), graph paper
The Hypothesis
1Predict: at which angle (15, 30, 45, 60, 90 degrees) will the panel produce the MOST voltage? Sketch your prediction curve.
The Build - Angle vs Output Test
2Set up: place the panel flat on the table. Shine flashlight directly down from exactly 1 foot above. Connect multimeter to panel leads - read voltage. This is 90 degrees (perpendicular = maximum).
How to Use a Multimeter for Beginners
Eye-level walkthrough of DC voltage measurement - same technique you're using to read solar panel output.
3Tilt panel to 60 degrees (using protractor). Flashlight stays in same spot, pointing straight down. Record voltage.
4Tilt to 45 degrees. Record.
5Tilt to 30 degrees. Record.
6Tilt to 15 degrees. Record.
Measuring the Impact of Solar Panel Tilt Angle
Field demo of voltage output changes as a panel tilts from horizontal toward the sun - connects directly to your chart.
7Chart it: angle on X-axis, voltage on Y-axis. Draw the curve.
8Calculate: voltage at 45 degrees as a percent of voltage at 90 degrees. Is it close to the 70% theoretical?
Real solar installers run this exact test on every rooftop they quote. A 5-degree mis-tilt on a 10 kW system costs about thousands per year. Multiply across a 25-year system life: real money left on the table. GRID Alternatives Bay Area teaches every trainee to verify tilt before bolt-down.
Phase 3: Apply

Session 10: Heat, Metal, Math
Pathway - Welding - Heat, Joints, and Metallurgy
0%
Phase 1: Spark
FACILITATOR PREP — Read 30 minutes before class.
Pre-stage: cut 140 cardboard strips ahead of time (2in x 6in — scoring with a box cutter is faster than scissors). 4 hot-glue-gun stations with sticks and a heat-resistant pad. Open the Weld Joint Inspector app on the projector for the warmup demo.
Watch for: low-temp glue guns are still 250 °F — first-time users tend to touch the nozzle. Brief once, demo once, then enforce one-hand-on-the-handle. Have a cup of cool water by each station in case of contact.
Success looks like: every pair tests all 5 joint types and can rank them by strength after destructive testing, AND can identify which of their broken joints shows 'fiber pull-out' (good weld) vs. clean peel (bad weld).
If it stalls: the 'overheated weld vs cold weld' comparison is the money moment. Run it side-by-side at the front so the whole class watches one team pull two welds apart.
Woven notebook: open your notebook now. Use it to capture every prediction, partner discussion, and question that comes up in this phase. Your notebook is the record of your thinking.
Welcome to Session 10! Today you will predict and rank five common weld joints by strength, then test the predictions with foam-core models and analyze where each one fails.
This session sits at the intersection of metallurgy and structural design: the joint type sets the strength ceiling. Pick the wrong one and the bridge, the chassis, the pipe fails on you.
The Hook
A San Francisco crane operator hooked up to a 4-ton load. The lifting bracket failed at the weld. The boom dropped. Investigation: the welder used a lap joint where structural code required a fillet on a butt joint.
No one died, but it cost millions of dollars in damages and a career. The same skill the welder skipped - knowing which joint goes where - is the first thing you learn at Laney College Welding. Today you learn it too.
5 Weld Joint Types Every Beginner Must Know
Quick orientation to butt, lap, T, corner, and edge joints before you predict which one fails first.
Welding is not gluing. It is melting two pieces of metal until they become ONE. The art is controlling the fire - just hot enough to fuse, not so hot you crack it.
Foundations - The 5 Joints
Every weld on earth is one of these 5 shapes:
1. BUTT - two pieces end to end
2. LAP - one on top of the other
3. T - one perpendicular to the other
4. CORNER - two meeting at an edge
5. EDGE - two pieces meeting flush at their edges
Tolerance in welding: plus/minus 1 mm on joint gap. Heat input is measured in amperage - too many amps and you burn through the metal; too few and the weld is weak. Travel speed matters too: too slow = wide heat affected zone (HAZ) and brittle cracks; too fast = cold, weak weld.
This is why welders say 'dial it in.'
1Think about something in your life that needed to be JOINED. What held it together? What did not?
Phase 2: Build
Woven notebook: keep your notebook open as you build. Record your hypothesis, every measurement and observation, and what surprised you. Your notebook is your lab record for this session.
Materials per pair: 1 hot glue gun (low-temp if possible), 6 glue sticks, 10 pieces of cardboard strip (2in x 6in), 1 stopwatch, 1 notebook. Safety: hot glue burns - keep hands off glue tip.
1Read above (1 min). Then continue.
Safety: hot glue guns reach 250-380 F. One hand on the gun, nozzle down, never point at a partner. Keep a cup of cool water nearby for accidental skin contact. Unplug between welds.
Before you touch glue, get your hands on the simulator. The Weld Joint Inspector below lets you stress-test each joint type with controlled heat input and travel speed. Use it to predict before you build.
2Open the Weld Joint Inspector above. In the Joint Library tab, click each of the 5 joint types and read the baseline strength. Which is strongest? Which is weakest?
3Switch to Stress Test Bench. Pick BUTT joint, set heat input to 100% and travel speed to 100%. Press Apply Load. Where does it break?
4Now run BUTT joint with heat input 70% (cold weld) and 150% (overheated). Watch where the failure shifts: cold welds break at the FUSION line, overheated welds break in the HAZ (heat-affected zone).
5Try Inspection Mode. Call ACCEPT, REPAIR, or REJECT on 8 real-world welds. Score yourself out of 8 - this is what a Certified Welding Inspector does every day.
The Hypothesis
6Predict: which of the 5 joint types will hold the MOST weight? The LEAST?
The Build - Cardboard Welding Stress Test
7Make each joint with a MEDIUM amount of glue (about 2 seconds of glue flow per joint): butt, lap, T, corner, edge. Label each one.
8Let all joints cool for 2 minutes.
9Stress test: hold the joint with one hand. Pull the other side steadily until it breaks. Note which joint type broke first, second, etc. Rank 1-5.
10Now test HEAT INPUT: make two MORE butt joints - one with MINIMAL glue (1 second), one with TOO MUCH glue (5+ seconds, messy puddle). Stress test both. Which held better?
Detailed Explanation of the Heat Affected Zone in Welding
Why the area next to the weld loses strength - the HAZ is what fails when heat input is wrong.
11Chart it: joint type on X-axis, rank of strength on Y-axis.
12Inspect your broken joints. Look at where the cardboard tore vs. where the glue peeled clean. Good welds pull out cardboard fibers; bad welds pop off the surface. Write which category each of your joints fell into.
13Debrief as a pair: if you had ONE more try, which joint would you redesign first, and what would you change about the glue amount or cooling time?
Too little glue = weak weld. Too much glue = messy weld, full of trapped bubbles and brittle zones (the real-world HAZ). Laney College welding students drill this exact tradeoff for weeks before they ever strike an arc.

Pathway - Aviation Maintenance - Lift, Drag, and Inspection
0%
Phase 1: Spark
FACILITATOR PREP — Read 25 minutes before class.
Pre-stage: 2 torque-wrench stations with fastener kits, 2 Bernoulli demos (paper strip + straw — DIY). Pre-print 35 cardstock airfoil cutouts. Open the Preflight Inspection app on every laptop.
Watch for: students over-tightening torque wrenches past the click (damages the wrench AND the part — real cost in a hangar). The click means stop, not 'one more crank'.
Success looks like: every pair completes a 12-item preflight checklist on the app, AND can explain why under-torque is more dangerous than over-torque on a control surface.
If it stalls: the Air Florida Flight 90 reframe works — 'one missed checklist item killed 78 people'. The preflight is the math anchor of the whole session.
Woven notebook: open your notebook now. Use it to capture every prediction, partner discussion, and question that comes up in this phase. Your notebook is the record of your thinking.
Welcome to Session 11! Today you will run a paper-airplane preflight, then walk a real Cessna 172 inspection - 30 items, 6 zones, every miss a story you'd have to tell the FAA.
This session sits at the intersection of physics and inspection: lift, drag, weight, thrust - and the human discipline that catches the loose bolt before takeoff. A&P mechanics live in this loop.
The Hook
In 2003, a small plane crashed in Indiana minutes after takeoff. Investigation found a fuel cap left loose during preflight. Fuel siphoned out. The engine quit at 800 feet.
A&P mechanics catch this every day with a 30-item walkaround. They check propeller nicks, fuel sumps, tire wear, control surfaces. They write down every observation. They ground the airplane if anything is unclear.
Today you do the same walkaround - on paper first, then on a real Cessna 172 in the simulator.
How to Preflight an Airplane
Walk-around inspection on a Cessna 172 - the same routine an A&P does every morning at SFO.
A commercial jet has 6 million parts. Every one of them is inspected on a schedule. That is why planes crash so rarely - not luck, math.
Foundations - Why Planes Fly
Four forces on every flying object:
- LIFT (up) - from the wings
- WEIGHT (down) - gravity
- THRUST (forward) - engines
- DRAG (backward) - air resistance
Wings create LIFT because air moving over the curved top moves FASTER than air under the flat bottom. Faster air = lower pressure. Higher pressure pushes the wing UP.
Two key angles an A&P mechanic tracks:
- ANGLE OF ATTACK - how tilted the wing is relative to oncoming air. Too steep = stall.
- DIHEDRAL - the upward V angle of the wings. Gives lateral stability.
Control surfaces (flaps, ailerons) change the angle and shape of the wing in flight. A&P mechanics inspect these every 100 flight hours.
1Have you ever made a paper airplane that went SHOCKINGLY far? What did it look like?
Phase 2: Build
Woven notebook: keep your notebook open as you build. Record your hypothesis, every measurement and observation, and what surprised you. Your notebook is your lab record for this session.
Materials per pair: 9 sheets of printer paper (3 per design), tape measure or meter stick, open hallway or classroom space, notebook
1Read above (1 min). Then continue.
Safety + setup: paper planes can poke an eye if thrown at someone's face. Fly in the same direction as a class, never across the room into another team. Watch for crowded zones. If your design ends up in flight near a person, ground it and reset. No throwing during retrieval - walk and pick up, then return to the line.
The Hypothesis
2Predict: which design will fly the farthest? FLAT WING, ANGLED WING (dihedral up), or WITH FLAPS (small folded tabs on back edges)?
The Build - Aerodynamics Lab
3Design 1 - FLAT WING: classic dart shape, wings parallel to body. Build 3 identical copies.
4Design 2 - ANGLED WING (dihedral): classic dart, but wings bent slightly UP in a shallow V. Build 3 copies.
Dihedral and Lateral Stability
Why Y-shaped wings self-correct - apply the same principle to your angled-wing paper plane.
5Design 3 - WITH FLAPS: flat wing but fold tiny 1 cm flaps UP at the trailing edge of each wing. Build 3 copies.
6Fly test: same thrower, same height, same force, 3 flights each design. Measure distance. 9 flights total.
7Chart it: design on X-axis, average distance on Y-axis. Which won?
8Now INSPECT your winning plane. Any crease misalignment? Any weight imbalance? How could YOU improve it?
9Rebuild your winning design with ONE deliberate change (fold a slightly different angle, shift the nose weight, or trim one wingtip). Fly it 3 more times. Did the change help or hurt?
That inspection you just did? EXACTLY what an A&P mechanic does at the start of every shift at United MRO at SFO. They check wing surface alignment, trailing-edge control surfaces, and rivet seating. Same discipline, higher stakes.
Launch the Pre-Flight Inspection Trainer
Paper planes showed you that small design changes change the flight. On a real Cessna 172, small inspection misses change whether it comes back. The trainer gives you the same walk-around an A&P does every morning at SFO and OAK.
10Tap 'Inspect the Aircraft.' Top-down Cessna 172 with 6 clickable zones - cockpit, tail, both wings, engine/nose, static ports. Each round hides 3-5 random defects across 30+ inspection items. You decide PASS, NOTE, or GROUND for each item. Miss a red defect and the app shows you the real-world consequence (loss-of-control, engine failure, instrument failure in flight).
11Switch to 'Defect Library.' 15 real defects with custom SVG illustrations - tire cord showing, prop nicks, water in fuel sample, blocked Pitot tube, bird nest in intake. Filter by category. Each entry gives the fix and who you'd call (mechanic, AOG service).
12Finish with 'A&P Quiz.' 10 questions modeled on real FAA A&P exam topics - prop nick depth limits, fuel sump procedure, tire wear thresholds, AOG response. Bay Area career anchors named: Gavilan College, College of San Mateo, Aircraft Spruce.
Notice the app's rule: when in doubt, GROUND it. There is no inspection where 'monitor the visible tire cord and we'll fly today' is the right call. A delayed flight costs 50k. A lost aircraft costs everything.
Phase 3: Apply
Woven notebook: as the answers come into focus, write them down. Note where the real-world numbers matched your prediction and where they were different. The reveal only sticks if you put it in your own words.
Why Every Rivet Matters
A Boeing 737 has about 600,000 parts. A 747 has about 6 million. Every one is on an inspection schedule.
A&P (Airframe & Powerplant) mechanics perform:
- Line checks (pre-flight, 15-30 min)
- A-checks (every 400-600 flight hours, 20-80 labor hours)
- C-checks (every 20-24 months, 2-3 week deep inspection)
- D-checks (every 6-10 years, plane torn down to frame)
United Airlines' biggest MRO base is at SFO. It runs C- and D-checks on the domestic fleet. That facility alone employs thousands of A&P mechanics, avionics techs, and inspectors.

Session 12: The Robot's Brain
Pathway - Robotics / Mechatronics - Coordinates, Code, and AI
0%
Phase 1: Spark
FACILITATOR PREP — Read 30 minutes before class.
Pre-stage: every student needs a laptop + free Tinkercad account (autodesk.com/tinkercad — facilitator pre-creates a class code if possible). Tape a 12-inch square on the floor with painter's tape for the human-robot warmup. Open the Robot Kinematics Drawer on the projector for the Round 0 demo.
Watch for: Tinkercad Circuits has a learning curve — the drag-from-component-bin motion isn't intuitive. Spend 3 minutes at the start of Round 2 walking the class through 'drag Arduino, drag breadboard, drag LED' on the projector before turning them loose.
Success looks like: every student has a working LED-blink simulation by Round 2 minute 10, and at least half progress to a working servo sweep before Round 3.
If it stalls: the Tinkercad starter circuit gallery (tinkercad.com/circuits → 'Starters') has pre-built blink and servo examples. Have students remix one rather than build from scratch — same learning, half the friction.
Woven notebook: open your notebook now. Use it to capture every prediction, partner discussion, and question that comes up in this phase. Your notebook is the record of your thinking.
Welcome to Session 12! Today you will program a robot to draw shapes by stacking forward, turn, and loop commands, and debug the kinematics like a Tesla Fremont line tech.
This session sits at the intersection of geometry and code: every robot move is a coordinate change. Write the code right, the robot draws a square. Write it wrong, it draws nonsense and the line stops.
The Hook
A Tesla Fremont line robot welds 4,500 spot welds per shift on a Model 3 frame. One degree of joint drift and the welds miss. One bad sensor and the line stops. Cost of a 1-hour line-down event: millions of dollars.
The person who finds the bug, recalibrates the joint, and restarts the line is a robotics technician with a community college Mechatronics AS. Today you start with the kinematics that drive every move.
Pick and Place Robot Arms: 3D Animation
How an industrial robot arm uses joints, motors, and code to put things exactly where they belong.
Every industrial robot in the world runs on two things: coordinates (WHERE it is) and logic (WHAT to do next). Both are teachable in minutes.
Foundations - Two Simple Ideas
1. COORDINATE FRAMES: Every robot has a WORLD frame (fixed point in factory), a TOOL frame (tip of its arm), and JOINT frames (each motor angle). It has to know all three to not crash.
2. PLC LOGIC (Boolean): AND, OR, NOT, written as 'ladder logic' on a factory floor.
- IF temperature > 100 AND pressure < 50: shut off valve
- IF button pressed OR sensor tripped: start conveyor
- IF NOT part detected: skip step
That is it. Millions of lines of factory code are built from these pieces.
1Describe how you would walk from the door of this room to the center, using only 'forward,' 'back,' 'turn left,' 'turn right,' and a number of steps.
Phase 2: Build
Woven notebook: keep your notebook open as you build. Record your hypothesis, every measurement and observation, and what surprised you. Your notebook is your lab record for this session.
Round 0 - Visual Warmup (5 min)
Before you blindfold anyone, get your eyes on what coordinate commands actually look like. The Robot Kinematics Drawer lets you type Forward / Turn / Pen-Down commands and watch a virtual robot draw the path. 5 minutes here makes the next 60 minutes click.
Robot Arms: Basic Concepts
Plain-English intro to the joints, motors, and code that drive every move in the next app.
1Open the Robot Kinematics Drawer above. Type a sequence of Forward / Turn / Pen-Down commands to draw a 12-inch square. The virtual robot shows you exactly what your code does - so when you blindfold your partner in Round 1, you already know how the commands feel.
2Try a triangle next. Then a star if you have time. Notice how each shape needs a specific TURN angle - same problem you'll hit with the AI in Round 3.
Programmers call this 'pseudocode' - writing the steps out before you commit to a real robot. Doing it visually first builds the mental model. You'll be faster on the Edison and sharper at spotting the AI's bugs.
Round 1 - Human Robot (15 min warmup)
3Predict: can you program a blindfolded human 'robot' to draw a 12-inch square using ONLY coordinate commands?
4Tape paper flat on the floor. Partner A is blindfolded with marker in hand at one corner. Partner B gives ONLY: 'Forward N inches,' 'Turn N degrees left/right,' 'Marker down/up.' No hints. No 'a little to the right.' Try once. Examine the result.
5Switch roles. Try once more, faster, using what you learned. Don't stress about perfect - this round just gives you the FEELING of writing code for a body that can't see.
Round 2 — Tinkercad Circuits: Build a Virtual Robot Arm (25 min)
You just programmed a human robot with English commands. Now you program a REAL Arduino with REAL code — except the wires, the breadboard, the LED, and the servo all live inside your browser. Same skills a robotics technician uses on day one, $0 of hardware, no risk of frying anything.
Tinkercad Circuits: Create Your First Arduino Circuit
Watch this together as a class before opening Tinkercad. 6 minutes. Covers signing in, dragging the Arduino + breadboard + LED, wiring up, and running the simulator.
6Open tinkercad.com in your browser. Click 'Sign in' (use the class Google account your facilitator gives you, or your school account). Once you're in the dashboard, click 'Circuits' on the left sidebar, then click the big '+ New' button to create a new circuit. Time-box: 3 min for sign-in + new circuit.
7From the component panel on the right, drag onto your workspace (in this order): (1) Arduino Uno R3, (2) Breadboard small, (3) LED (any color), (4) Resistor (set the value to 220 Ω in the inspector that pops up). Time-box: 3 min.
8Wire it up: click the LED's long leg (anode) → drag a wire to any row on the breadboard. Click that same row → drag a wire to Arduino pin 13. Click the LED's short leg (cathode) → drag a wire to one end of the resistor. Other end of resistor → Arduino GND. Tinkercad will check your wiring as you go — green is good, red means short circuit (fix before simulating).
9Click the 'Code' button at the top right. Switch from 'Blocks' to 'Text' mode (you'll see real Arduino C++ — this is the same language robotics techs write professionally). Paste this code:
void setup() {
pinMode(13, OUTPUT);
}
void loop() {
digitalWrite(13, HIGH);
delay(500);
digitalWrite(13, LOW);
delay(500);
}
Click 'Start Simulation'. Your LED should blink every half second. If it doesn't blink, check the wire colors (green = connected, red = broken).
Win moment: every student should see a blinking LED before moving on. Take a screenshot — it's your first working Arduino program, and it's identical to what every robotics technician writes on their first day of training.
Now add a servo — the muscle of every robot arm.
Tinkercad Circuits: Servo Motor Sweep with Arduino
5-minute walkthrough of wiring a servo to an Arduino in Tinkercad and writing the sweep code. Pairs watch on their own laptops before building.
10Stop your simulation. From the component panel, drag in: (1) Micro Servo. Wire the servo's red wire to Arduino 5V, the black/brown wire to GND, and the orange/yellow signal wire to Arduino pin 9. (Tinkercad auto-colors the wires for you — match the colors.)
11Replace your code with this servo-sweep program:
#include <Servo.h>
Servo myServo;
void setup() {
myServo.attach(9);
}
void loop() {
for (int angle = 0; angle <= 180; angle++) {
myServo.write(angle);
delay(15);
}
for (int angle = 180; angle >= 0; angle--) {
myServo.write(angle);
delay(15);
}
}
Click 'Start Simulation'. Your servo should sweep from 0° to 180° and back — like the wrist of a robot arm.
12Modify and predict: before you change anything, predict what will happen if you change delay(15) to delay(5). Then test it. Now try delay(50). Now try changing the loop so it sweeps only from 0° to 90° (a wrist that bends but doesn't over-rotate). Every modification is a real engineering decision.
Real-world bridge: every industrial robot arm at a Tesla plant, every surgical robot at UCSF, every drone-arm in a warehouse runs the same servo-sweep logic you just wrote — with more servos, faster microcontrollers, and safety interlocks. The core code looks the same.
13Save your circuit (it auto-saves to your Tinkercad account, and you can return to it anytime — even from home). Copy the share link and paste it into your notebook. This is your first portfolio piece for the robotics pathway.
Round 3 - AI as Code Partner (15 min)
AI literacy moment: AI assistants will write code for you. Your job is NOT to type prompts - it's to evaluate what the AI gave you and find what it got wrong. AI is right about 70-80% of the time on first try. The other 20-30% will ruin your robot, your circuit, or your whole project if you don't catch it.
14Ask the class AI on the shared laptop: 'Write Edison robot code in EdBlocks logic (simple commands only) to drive a perfect 30 cm equilateral triangle.' Read the response with your partner.
15FIND THE BUG: an equilateral triangle has 60-degree interior angles, but the robot has to TURN the EXTERIOR angle (120 degrees) to go to the next side. Did the AI get this right or wrong? Most AIs get this wrong on first try. Whatever the AI said, translate it to EdBlocks and run it. Compare to expectation.
16If the AI was wrong: ask it WHY it got the angle wrong, then ask for a corrected version. Verify. If the AI was right: ask it for code that draws a 5-pointed star, then check the geometry yourself before running. Stars are even harder to get right - they need a 144-degree exterior turn.
Career connection: every modern robotics technician, mechatronics engineer, and industrial automation programmer uses AI to draft code - and is paid to find the AI's mistakes. The job is no longer 'write the code from scratch.' The job is: read the code the AI wrote, find where it lies, fix it, and ship something that works in the real world. You just did the entire job in 15 minutes.
Phase 3: Apply
Woven notebook: as the answers come into focus, write them down. Note where the real-world numbers matched your prediction and where they were different. The reveal only sticks if you put it in your own words.
What Your Experiment Just Simulated
Every industrial robot at Tesla Fremont, GM, Stryker, and Boeing runs code that looks like this (simplified):
MOVE (x=150, y=200, z=50)
GRIP
IF part_detected THEN
MOVE (x=400, y=200, z=50)
RELEASE
ELSE

Session 13: Speaking Binary
Pathway - IT Support - The Language of Computers
0%
Phase 1: Spark
FACILITATOR PREP — Read 20 minutes before class.
Pre-stage: lay out 6 ethernet cables, the RJ-45 crimping kit, 2 old PCs (powered OFF, no cords attached), and the anti-static wrist straps at 4 hardware stations. Print 70 binary/subnetting worksheets.
Watch for: students opening PC cases without grounding (static can fry components even on dead boards — make the wrist strap a hard rule). And the binary conversion is where most students freeze — have the powers-of-2 ladder pre-written on the whiteboard.
Success looks like: every student converts at least 3 IP octets to binary, AND can name the role of every major component in the disassembled PC (CPU, RAM, motherboard, power supply, drive).
If it stalls: jump to the Binary Translator app on the projector as a class race — type a name, watch it convert. Re-engages instantly, then back to the worksheet.
Woven notebook: open your notebook now. Use it to capture every prediction, partner discussion, and question that comes up in this phase. Your notebook is the record of your thinking.
Welcome to Session 13! Today you will translate your name into binary by hand, then debug an 'AI' that keeps flipping bits in real strings - the same fault-finding muscle every IT support tech runs on.
This session sits at the intersection of language and electronics: every letter, every email, every photo on every device is binary at the bottom. If you can read it, you can fix it.
The Hook
A hospital sysadmin's pager goes off at 2 AM. The patient-records database is rejecting Spanish names with apostrophes - O'Brien, D'Angelo, O'Connell.
She traces it through the logs and finds the bug: a character-encoding mismatch flipping the apostrophe (ASCII 39) to a semicolon (ASCII 59). One bit wrong. Patient records lost.
She fixes it in 20 minutes because she can read binary at a glance. Today you build that same muscle.
Binary - The Simplest Explanation
Counting and converting binary numbers in plain English - the foundation under every IT support call.
Everything you've ever typed, texted, streamed, or uploaded - your computer stores as nothing but 0s and 1s. A text message is just a string of 0s and 1s. So is a movie. So is a password.
Foundations - How Binary Counts
Normal counting (base 10): 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.
Binary (base 2): 0, 1, 10, 11, 100, 101, 110, 111, 1000.
Each binary digit (bit) is a power of 2, read right to left:
...64, 32, 16, 8, 4, 2, 1.
So 101 in binary = 4 + 0 + 1 = 5 in normal numbers.
1010 = 8 + 0 + 2 + 0 = 10.
ASCII = each letter has a number. A = 65. a = 97. Space = 32. Every character, 8 bits.
1Write the number 7 in binary. (Hint: 4 + 2 + 1.)
Phase 2: Build
Woven notebook: keep your notebook open as you build. Record your hypothesis, every measurement and observation, and what surprised you. Your notebook is your lab record for this session.
Materials: printed ASCII chart (one per student, or displayed), pencil, notebook. Also write a secret message on the whiteboard in binary.
The Hypothesis
1Predict: how many bits (0s and 1s) will your FIRST name take up, if each letter is 8 bits?
The Build - Encode Yourself
2Using the ASCII chart, look up each letter of your first name. Write the decimal number.
3Convert each decimal to 8-bit binary. (Teacher demos the first letter on the board.)
4Write your full first name as a continuous string of 8-bit binary.
5Trade with a partner. Decode their name back into letters. Check their work.
6Secret message: on the board, the teacher has written a 3-word message in binary. Decode it as a class.
7Count: was your predicted bit length correct?
8Pick one letter in your name and write it in HEX (base 16) using the ASCII chart. Check with a partner. Every IT professional reads hex dumps at some point.
Every email, every text, every Instagram post is exactly this encoding. You just did the fundamental work of every IT professional on earth.
The AI Test - Can the Computer Spell Your Name?
Now flip it: ask an AI to do what you just did by hand. AIs encode binary all the time - and they sometimes hallucinate the wrong ASCII value, especially for capital letters or names with unusual characters. Your job is to find the lie.
9On the shared classroom laptop, ask an AI: 'Convert the name [YOUR FIRST NAME] to 8-bit binary, character by character.' Get the response.
10Check it letter by letter against the ASCII chart. Mark any letter the AI got wrong. Most of the time it gets all letters right - but sometimes it slips on a single character, especially the capital letter at the start.
11If the AI was wrong: tell it what's wrong. See if it corrects itself. If it was right: ask it the same question for a name with a hyphen or apostrophe (like O'Brien or Anne-Marie). AIs handle punctuation worse than letters. Find the next bug.
Why this matters: every IT support job in 2026 includes a moment where someone hands you AI-generated code, configuration, or documentation and says 'just check this.' If you can't read the underlying language - in this case, binary - you can't catch the AI's mistakes. That's the new ceiling for IT careers.
Launch the Binary Translator + AI Bug Hunter
You converted your name by hand against the ASCII chart. Now flip the camera: the AI converts names too, and sometimes gets one letter wrong. Your job is to find the bug. Same skill every IT support tech needs in 2026.
Binary Numbers in 60 Seconds
Sixty-second refresher right before you decode names with the translator.
12Tap 'Translate Your Name.' Type any string and watch the live breakdown - char | dec | hex | 8-bit binary - plus the continuous bitstream. Use reverse mode to paste a bitstream and decode it. Letters are teal, digits gold, punctuation coral - you'll start to read binary at a glance.
13Switch to 'AI Bug Hunter.' 8 challenges of escalating difficulty. The 'AI' has encoded a name with one or more bits wrong (off-by-one ASCII, hyphen-to-space, apostrophe-to-semicolon, case-bit flip, phantom high-bit, non-ASCII fail). Click the wrong bits to flip them. Submit when fixed. The cafe challenge is the punchline - the AI didn't even fail gracefully on a non-ASCII character.
14Finish with 'Hex / Binary Quiz.' 8 conversions and ASCII landmarks - MAC addresses, IP octets, hex colors, file headers. CCSF Computer Networking and Mission College CompTIA program details are in the answer explanations.
Watch what happens with the apostrophe in O'Brien. The AI's most common bug is replacing punctuation with the next ASCII code. If you can read binary, you can catch it. If you can't, the bug ships.
Phase 3: Apply
Woven notebook: as the answers come into focus, write them down. Note where the real-world numbers matched your prediction and where they were different. The reveal only sticks if you put it in your own words.

Session 14: Thinking Like a Hacker
Pathway - Cybersecurity - Risk, Passwords, and Defense
0%
Phase 1: Spark
FACILITATOR PREP — Read 20 minutes before class.
Pre-stage: 6 USB drives (wiped clean) loaded with the CTF challenge files. Print 35 cipher-wheel cutouts. Lay out the tabletop exercise cards at a center station. Open the Phishing Hunter app on every laptop.
Watch for: students sharing answers across pairs during the CTF — this is OK socially but kills the learning. Spread pairs out, and rotate which USB drive each pair has.
Success looks like: every pair flags at least 5 of 8 phishing emails correctly, AND solves at least one cipher challenge using their wheel.
If it stalls: the 'how I got phished' personal-story prompt works — ask the class 'who has gotten a text from a 'bank' that wasn't real?' Hands go up. Now the threat is in the room, not abstract.
Woven notebook: open your notebook now. Use it to capture every prediction, partner discussion, and question that comes up in this phase. Your notebook is the record of your thinking.
Welcome to Session 14! Today you will hunt phishing emails as the defender, build the strongest password your pinky can remember, and write 3 bullets diagnosing a fake admissions email.
This session sits at the intersection of human psychology and computer security: every successful attack uses urgency, fear, or trust. You're being trained to spot the bait before anyone clicks.
The Hook
A Bay Area community college lost millions of dollars in 2024 to a single phishing email. An accountant clicked a link that looked exactly like a vendor invoice. Wire transfer issued in 14 minutes.
The school hired a SOC analyst at a strong wage who now spots and stops 30+ similar attempts per week. Same email, different domain, different excuse. The analyst's only weapon: she reads carefully and asks 'does this look right?'
You are being trained to be that analyst. Today you start with the same eye she uses.
Phishing Explained in 240 Seconds
Four minutes on how attackers trick people into clicking - the threat you'll be hunting today.
Cybersecurity is a mindset before it's a skill. Hackers think: 'How would I break this?' That question - asked every day at every company - is the defense.
Foundations - Risk = Likelihood x Impact
Every security decision is this equation:
- How LIKELY is this to be attacked? (1 = unlikely, 5 = certain)
- How BAD if it succeeds? (1 = minor, 5 = catastrophic)
Risk score = likelihood x impact.
Example:
- Password on sticky note in office: likelihood 4 x impact 5 = 20 (URGENT)
- Strong password rotated quarterly: likelihood 1 x impact 5 = 5 (LOW)
Attack vectors:
- Phishing: fake emails that look real (#1 way companies get hacked)
- Password attack: brute-force guessing
- Social engineering: tricking humans
- Malware: software sneaking in
1What's one 'lock' in your digital life you'd rate 4+ on risk right now?
Phase 2: Build
Woven notebook: keep your notebook open as you build. Record your hypothesis, every measurement and observation, and what surprised you. Your notebook is your lab record for this session.
Materials: the password list below, notebook, pencil
The Hypothesis
Rank these 5 passwords from STRONGEST to WEAKEST. Justify each ranking.
THE 5 PASSWORDS:
1. password123
2. CorrectHorseBatteryStaple
3. P@55w0rd!
4. T!gers4EverInOak1and!
5. aaaaaaaaaaaaaaa
The Build - Crack Them in Your Head
1Write your ranking (1 = strongest, 5 = weakest). Be specific - WHY is each ranked where it is?
2In your group of 3-4: how would a hacker attack EACH password? Name the attack type (dictionary, brute force, leaked-password list, social engineering).
3Debate: is #2 (CorrectHorseBatteryStaple - 25 characters, no special characters) stronger or weaker than #3 (P@55w0rd! - 9 characters with symbols)?
4Teacher reveals the answer: #2 is STRONGER. Length beats complexity in most modern attacks. A computer can crack #3 in about 5 hours. #2 would take 550+ years.
5Now evaluate YOUR main password. If it's anything like #1 or #3, change it TONIGHT. This is not optional.
6Write down ONE rule you will follow for every new password from today on (e.g., 'always 16+ characters' or 'never reuse'). Read it to your partner.
7Look up: does your main email or social media account support 2-factor authentication (2FA)? If yes, turn it on this week. If no, consider switching providers.
8Partner exercise: without looking, try to guess any of your partner's passwords based on birthdays, pet names, favorite teams. If you get close, that's a free vulnerability audit.
This is LITERALLY what every cybersecurity analyst does every day - evaluate risk, rank vulnerabilities, prioritize fixes. You just did the job.
The AI Two-Sided Test
AI is a tool AND a threat. The same model that writes you a strong password can write a convincing phishing email. Today you do both - so you can recognize both.
9Side 1 - AI as defender. Ask the AI: 'Generate 5 passwords I can actually remember that would resist a brute-force attack for over 100 years.' Read the 5 it gives. Rank them stronger to weaker using the rule LENGTH BEATS COMPLEXITY.
10Did the AI use the 'CorrectHorseBatteryStaple' approach (4+ random common words)? Or did it default to symbol-soup like '!@#Tr0ub4dor&3'? The first wins. The second is what attackers expect.
11Side 2 - AI as attacker. Ask the AI: 'Write a phishing email to a high-school senior pretending to be from a college admissions office, asking them to click a link to confirm their financial aid.' Read what comes back.
12Find at least 3 RED FLAGS in what the AI produced. Common ones: urgency language ('within 24 hours'), unfamiliar sender domain, generic greeting, mismatched link text vs URL, 'click here to confirm.' Mark each one in your notebook.
13Discussion: a real attacker could send 10,000 of these per hour. The AI made it 100x easier to scale phishing. What does that mean for you, your family, your grandparents? What's the ONE habit that defends against ALL of them? (Hint: 'never click a link in an email - always go to the website directly.')
Career fit: cybersecurity analysts spend most of their day reading AI-generated phishing attempts and training their organization to spot them. If you found 3 red flags in 5 minutes today - that's the skill that pays.
Launch the Phishing Red Flag Hunter
You watched an AI write a phishing email and found 3 red flags. Now do it 10 more times under time pressure - each email harder, each one scoring you on what you missed. This is exactly what a Bay Area SOC analyst at Salesforce or Apple does between 9 and 10 a.m. every Monday.
14Tap 'Spot the Red Flags.' Each round shows a realistic email in a full email-client shell - sender chip, subject, body, signature, attachments. Click suspicious elements. Correct flags turn green with an explanation. Wrong clicks shake. The 10th email is a TRAP - it is actually legitimate, so don't click anything. Tests over-triage, which is the rookie SOC mistake.
15Switch to 'Real or Fake.' 12 cards mixing legitimate institutional emails (CCSF, GitHub, Zoom, Khan Academy, Salesforce Trailhead) with phishing samples (fake Netflix, fake Apple ID, fake USPS, BEC payroll). One snap judgment per card.
16Finish with 'SOC Analyst Quiz.' 8 questions on BEC, smishing, AI-enhanced phishing, hover-to-verify URLs, and the CCSF Security+ / Mission Cybersecurity AS / Skyline CyberPatriot pathway.
AI made phishing 10x more convincing in 2024. The prose is clean. Trust the URL, not the writing. Hovering over a link shows the real destination - that's your strongest defense.
Phase 3: Apply
Woven notebook: as the answers come into focus, write them down. Note where the real-world numbers matched your prediction and where they were different. The reveal only sticks if you put it in your own words.

Session 15: Precision at the Molecular Level
Pathway - Biotech Lab Tech - Dilutions and Standards
0%
Phase 1: Spark
FACILITATOR PREP — Read 30 minutes before class.
Pre-stage: 3 micropipette stations (pipette + tips + 96-well plate). Pre-fill 8 stock-dye solutions in small cups. Safety glasses REQUIRED — count them out before students arrive. Open the Dilution Lab app on every laptop.
Watch for: students push the pipette plunger to the SECOND stop when drawing up (over-aspirates). The rule is: first stop to draw, second stop to dispense. Demo once at the front.
Success looks like: every pair completes a 1:10 serial dilution across 5 wells with visibly graded color steps, AND can calculate the final concentration without help.
If it stalls: the COVID-PCR dilution story is the rescue — ask 'how do you find 1 virus in a billion drops?' Serial dilution is the answer. Then back to the pipettes.
Woven notebook: open your notebook now. Use it to capture every prediction, partner discussion, and question that comes up in this phase. Your notebook is the record of your thinking.
Welcome to Session 15! Today you will pipette a 10-fold serial dilution by hand, build a standard curve from your readings, and find the unknown concentration like a Genentech lab tech.
This session sits at the intersection of math and biology: every assay starts with a clean dilution. If the math is wrong, every reading downstream is wrong - and the drug doesn't work.
The Hook
In a 2008 Cetus lab incident, a tech mis-pipetted a 10x dilution as a 100x dilution. Every reading downstream came in 10x off. The team chased the error for 3 weeks before realizing the dilution itself was wrong.
A biotech lab tech who can do clean dilutions is hired in 9 months at Genentech, Bayer, BioMarin - a strong wage starting. The one who fakes it gets caught the first time the standard curve doesn't fit.
Today you do the math and the pipetting.
Serial Dilution Method - Step by Step
Two-minute protocol on how each tube gets 10x more dilute than the last - the math under every biotech assay.
The Bay Area is the #1 biotech hub on Earth. Genentech, Gilead, 23andMe, BioMarin, Grifols - thousands of lab tech jobs. Every drug you take started as someone diluting a solution exactly right.
Foundations - C1V1 = C2V2
C1V1 = C2V2
(starting concentration) x (starting volume) = (ending concentration) x (ending volume)
Example: You have 10 mg/mL protein. You want 0.1 mg/mL protein. You need 100 uL of the diluted one.
10 x V1 = 0.1 x 100
10 x V1 = 10
V1 = 1 uL of concentrate + 99 uL of water = 100 uL at 0.1 mg/mL.
Beer's Law (bonus):
The more concentrated a colored solution, the MORE light it absorbs. Lab techs use absorbance readings to measure concentration - exactly what you'll do visually today.
1If you have 100 mL of juice at 50% strength and you want 100 mL at 10% strength, how much juice do you start with and how much water do you add?
Phase 2: Build
Woven notebook: keep your notebook open as you build. Record your hypothesis, every measurement and observation, and what surprised you. Your notebook is your lab record for this session.
Materials per pair: 6 small clear cups, water, food coloring (1 color), pipette (or medicine dropper), white paper (for background), notebook
1Read above (1 min). Then continue.
Safety: treat every lab liquid as unknown, no tasting, hands away from eyes. Wipe spills immediately. If a pipette tip drops, trash it, don't reuse. These are the same habits Genentech techs use with real reagents.
The Hypothesis
2Predict: after 5 rounds of 10:1 dilution, will you still SEE any color?
The Build - Serial Dilution Lab
3Line up 6 cups. Cup 1: 10 drops of food coloring + 90 drops of water (stock solution = 100% color).
4Cup 2: take 1 drop of water from cup 1 pipette to cup 2, add 9 drops of clean water. Stir. This is 10% color (1/10 dilution).
5Cup 3: 1 drop from cup 2 + 9 drops water. Stir. This is 1% color (1/100).
6Cup 4: 1 drop from cup 3 + 9 drops water. Stir. This is 0.1% color (1/1,000).
7Cup 5: 1 drop from cup 4 + 9 drops water. Stir. 0.01% color (1/10,000).
8Cup 6: 1 drop from cup 5 + 9 drops water. Stir. 0.001% color (1/100,000).
9Hold all 6 cups against white paper. At what cup does color become invisible to the eye? Record.
10Chart it: cup number on X-axis, visibility (1-10 scale) on Y-axis.
This serial dilution is the EXACT procedure used at every biotech company in the Bay Area to make standard curves for every drug, every assay, every quality control test. You just did it.
AI Fact-Check
11Ask an AI: 'Why do biotech labs use serial 10:1 dilutions instead of just diluting once at the final ratio?' Read the answer with your partner.
12Now fact-check it against what you just measured: the AI will likely talk about precision and pipette accuracy at small volumes. Did it explain WHY one big dilution is harder than many small ones? Could you have caught the AI lying if you HADN'T just done the experiment?
Lab tech reality: AI is now embedded in every electronic lab notebook (ELN). It drafts protocols. It reads your raw data and suggests interpretations. Lab techs who can't fact-check the AI against their own benchwork are the ones who get caught when the AI is confidently wrong - and biotech mistakes cost millions per batch. Your hands and the math you just did ARE your AI verifier.
Phase 3: Apply
Woven notebook: as the answers come into focus, write them down. Note where the real-world numbers matched your prediction and where they were different. The reveal only sticks if you put it in your own words.

Session 16: Pick Your Path
Capstone - Pick Your Path
0%
Phase 1: Spark
FACILITATOR PREP — Read 30 minutes before class.
Pre-stage: every student needs a laptop + free Canva account. Print 5 backup poster boards for any no-laptop fallbacks. Print the 35 color copies for the gallery walk AFTER students finish (allocate 10 min). Open the Pathway Picker app on the projector for any students still deliberating.
Watch for: students spending 25 of the 60 minutes choosing a Canva template (this is a graveyard). Hard-cap template selection at 3 minutes — 'pick any clean template, you can change later'.
Success looks like: every student walks out with a printed one-page pathway artifact AND has named their next step out loud to one other person.
If it stalls: the 30-second pitch round is the engine — even the most uncertain student commits when they hear themselves say the pathway name out loud.
Woven notebook: open your notebook now. Use it to capture every prediction, partner discussion, and question that comes up in this phase. Your notebook is the record of your thinking.
Welcome to Session 16! Today you will sort all 13 pathways by your style, your math, your hands, and your time horizon, then write the first 3 actions on the path you pick.
This session sits at the intersection of self-knowledge and pathway design: a good plan doesn't pick one career - it lines up the next 3 steps so any of 4 doors can open. Today you build that plan.
Bridge: 13 weeks of pathways, every one mapped to a real Bay Area provider with real salaries. Today you don't pick a winner. You sort the ones that fit your style, your math, your hands, your time horizon. Then you build the first 3 moves of the plan.
The Hook
From 13 weeks of pathways, you've met EMTs, phlebotomists, CNAs, MAs, rad techs, HVAC techs, solar installers, welders, A&P mechanics, robotics techs, IT support, cybersecurity analysts, and biotech lab techs.
Thirteen real entry doors. Real Bay Area providers. Real salaries. Real timelines.
Today you don't pick a winner. You sort. Which fit your style? Which match your math? Which respect your time? Which open the most second-doors? Then you write your first 3 moves.
Career Pathways and Why They Matter
Real students, real pathways, real entry points - a frame for the choice you'll be making today.
For 15 weeks you've met pathways into measurement, healthcare, trades, tech, biotech. Today you pick ONE. And you build proof that you're serious.
Foundations - Portfolio Thinking
An ARTIFACT is a physical piece of evidence that you're serious about a path. Colleges and employers don't want to hear what you WILL do - they want to see what you've ALREADY done.
A one-page Pathway Map is that artifact. It says:
- The cert you'd earn
- The Bay Area provider (actual name, location)
- Your realistic next step (this week? next semester?)
- Why THIS pathway for you personally
This is the piece of paper you hand to your TRIO advisor, your parents, your counselor. It's a commitment tool.
1Journal quietly (5 min): which pathway excited you most across 15 weeks? What did it make you feel?
Phase 2: Build
Woven notebook: keep your notebook open as you build. Record your hypothesis, every measurement and observation, and what surprised you. Your notebook is your lab record for this session.
Today you build a one-page pathway portfolio that you can actually send to a parent, a counselor, or a college admissions officer. The goal isn't a craft project - it's a publishable artifact that proves you know your next move. We'll use Canva and AI image tools the way every modern professional does.
Step 0 - Confirm Your Pathway (5-7 min)
If your pathway is already locked in, skip this and go to Step 1. If you're between two or three options, the Pathway Picker walks you through a quick set of preference questions and surfaces the 2-3 Bay Area pathways that best match what you've told us across 16 weeks. Use it as a tiebreaker, not a deciding voice - the gut check is still yours.
Career Pathways: Real Stories
Quick framing on how real students sort their pathway choices - then you do it in the picker.
1Open the Pathway Picker above. Answer each preference question honestly - hands vs screens, indoors vs outdoors, alone vs team, fast credential vs deep training. The app surfaces 2-3 strong matches with the actual Bay Area program names.
2Compare the app's top suggestion to your gut. If they match - you're done deliberating. If they don't match - your gut is probably right and the app showed you what you'd be giving up. Either way, declare your pathway out loud before moving on.
The Pathway Picker is also the artifact you can email to a counselor or parent for the conversation: 'these were my top matches, and here is the one I picked, and here is why.'
Step 1 - Pick (don't deliberate)
3Out loud or to yourself: 'My pathway is ______.' Pick. Do not deliberate. Trust your gut from the notebook you've been keeping for 16 weeks. You can always change later - today is about declaring.
Step 2 - Build the 3-bullet quick verdict in Canva
4Open canva.com. Sign in (free account is fine). Search templates for '3-bullet quick verdict' or 'resume one-page' or 'profile.' Pick a clean, modern template. Don't waste time on aesthetics - the template did the work.
Canva for Beginners - Tutorial
New to Canva? Watch this 5-minute getting-started tutorial before you build your pathway map. You'll learn how to pick a template, change text, and export to PDF.
No laptop today? Use the poster board fallback - markers, the same content sections, decorate the border. Ask for the backup template printed for the class. Don't let missing tech stop the artifact from getting built.
5Replace the template content with YOUR pathway content, in this order: (1) The pathway name, large, at the top. (2) The credential you'll earn (e.g., 'EPA 608 HVAC' or 'CPT1 Phlebotomy'). (3) The Bay Area provider + city (e.g., 'Laney College, Oakland'). (4) Your Next Step: THIS WEEK I will ___. NEXT SEMESTER I will ___. AFTER GRADUATION I will ___. (5) Why This Path For Me: 2-3 personal sentences. Not generic.
Step 3 - Generate Pathway Imagery with AI
6Use Canva Magic Studio (or Bing Image Creator) to generate ONE hero image that represents your pathway. Prompt example: 'A welder in blue coveralls working on a steel beam, golden hour lighting, photorealistic, no text.' Iterate the prompt 2-3 times until you get an image that feels like YOU could be the person in the photo. Time-box: 10 min max.
7AI literacy check: AI image generators sometimes get hands wrong, miscount fingers, or invent fake tools. Inspect your image carefully before placing it. If something looks off, regenerate. Never publish an AI image you haven't proof-read.
8Drop the AI image into your Canva 3-bullet quick verdict as the hero block at the top. Add 2-3 small icons for the credential, the provider, and your next step (Canva has free icons - search 'wrench,' 'stethoscope,' 'solar panel,' whatever fits).
Step 4 - Export and Walk
9Click Share to PDF. Download. Optional: send a copy to your phone or email. Print one color copy for the gallery walk.
10Stand up. Walk your 3-bullet quick verdict (printed or on screen) to ONE other person. Pitch your pathway out loud in under 30 seconds: 'I'm doing [pathway] because [reason]. My next step this week is [action].' Notice what surprises them. Notice what they were curious about.
What you just made: a recruiter, a college admissions reader, or a scholarship committee can scan your pathway 3-bullet quick verdict in 10 seconds and know exactly who you are. Most adults don't have one of these. You're 16-18 and you do. Update it once a year for the rest of your professional life.
Phase 3: Apply
Woven notebook: as the answers come into focus, write them down. Note where the real-world numbers matched your prediction and where they were different. The reveal only sticks if you put it in your own words.
Share and Witness
12-3 volunteers share their Pathway Maps. 60 seconds each. State: the pathway, the provider, the next step, and ONE sentence on why this matters to them.
2Class celebrates each share with applause. No critique. No ranking. Just witness.
3Take a photo of your Pathway Map for your portfolio (also send a copy to your phone or email so you do not lose it).
Every pathway on these posters is real. Every provider exists. Every phone number you find works. Today, you are no longer a student of possibilities. You are a person with a map.

Portfolio drop - Session 16 (Capstone - Pick Your Path):
You just did a real clinical/technical skill. Show it off. Pull out your phone, film 30-60 seconds of your final pitch (60 sec): the pathway you picked, why, and what skills you have built across the 16 weeks, and post it to the class Padlet. By Session 16 you have a 4-clip portfolio that shows the journey.
4Record your video (30-60 sec). Your final pitch (60 sec): the pathway you picked, why, and what skills you have built across the 16 weeks. Time-box: 5 min including filming and posting.
5Open the Padlet (below). Click the + button. Fill in:
- SUBJECT: "session 16 - your name - my pathway"
- BODY (1-2 sentences): what you did + one thing you learned about this career.
- ATTACH: your video clip.
Hit Publish. Your facilitator approves and the post goes live.
Phase 4: Pathway
Woven notebook: write down every pathway that catches your attention - the program name, the time-to-credential, the entry pay, the next step you would take. This is your real-world map.
Pathway: Pick Your Path - Spring Careers Lab
The First 20 Hours: How to Learn Anything (Josh Kaufman, TEDx)
20 hours of focused practice is enough to get past the frustration barrier with any new skill. Pick your pathway, put in 20 hours, and watch what happens.
From today's lab to the field:
What you did today: you sorted 13 pathways against your own style, math, hands, and time horizon, then wrote your first 3 actions on the path you picked.
What the pros do: every successful first-job hire writes a plan like yours: real provider, real timeline, real next move - then they show up.
Bay Area employers: All 13 pathways above - and your TRIO advisor
Starting pay: Wherever you choose - the door is real

Phase 5: Reflect
Woven notebook: take a few minutes. Answer every reflection question in writing. This is the moment the session moves from your head into your hands.
1What's the ONE thing you'll do THIS WEEK toward your chosen path?
2What's stopping you?
3Who in your life will you tell about this pathway - by Friday?
Keep your Pathway Map. Take a photo. Tell your TRIO advisor. Tell one person you love. Then take the one step you just wrote down.
You have the map. You have the path. The next step is yours.
Hold on to your notebook. Today's measurements, predictions, and pathway notes feed directly into the next sessions and into your final pathway plan in Session 16. Don't tear pages out.
