Grade 9 — start the project
Grade 9 — start one project
You are on one track. The project lasts four years. This year you start it and keep a log. The log is the start of the file you will send. Do not open a second project.
For Mechanical engineering, Electrical engineering, Computer science, Marine biology, Pre-med, and PhD on-ramp:
Every week, do four things inside that project:
- Compute a quantity with units, state the uncertainty, and say what decision it supports.
- Write one claim, two reasons, and one real objection. About one page.
- Read one short original — a figure and its caption, a statute section, a schematic, or a specimen — and write what it says, separate from a summary.
- Add to the log.
For Pre-law:
Every week, do four things inside that project:
- Mark which facts the clause uses and which it ignores, and write the result that follows.
- Write one claim, two reasons, and one real objection. About one page.
- Read one short clause and write what it says, separate from a summary.
- Add to the log.
Finish these rungs on the First Principles ladder. Each one has a gate. The rung is done only when the gate is done.
For Mechanical engineering, Electrical engineering, Computer science, Marine biology, Pre-med, and PhD on-ramp:
- Instructions a machine could follow
- Loops and branches
- Variables and state
- Function as a black box
- Balancing equations
- The coordinate plane
- Python: syntax and types
- Python: files and automation
For Pre-law:
Finish Instructions a machine could follow only, plus the memo below.
For Mechanical engineering, Electrical engineering, Computer science, Marine biology, and Pre-med:
School courses beside the project: algebra and geometry, and a first lab science, usually biology.
For Pre-law:
School courses beside the project: algebra. Add a lab science only if the major will require it.
For PhD on-ramp:
School courses beside the project: algebra and geometry. Add a lab science if the department you expect to name will examine it.
Mechanical engineering
Build an object that must hold a known load. Before the test, write the load and the failure point you expect. After the test, write the measured failure point and the difference. Justify the equation line by line: every step names the operation applied to both sides.
Done when a second person can rebuild the test from the log and get a failure point in the same region.
This week. Span a gap with a strip of cardboard or a thin wood slat. Write the mass you think will break it, in grams, before you load it. Add coins or sand until it fails. Record the mass that broke it and the difference from your prediction. Write the weight as mass times 9.8, and name the operation on both sides of each line.
Log for this week. Date. Length of the gap. Material. Predicted failure mass (g), written before loading. Measured failure mass (g). Difference. Weight = mass × 9.8, with each line naming the operation on both sides. Who will rebuild the test.
Electrical engineering
Build a circuit with a source, a resistor, and a meter. Write the expected current from the resistance before you close the switch. Record the measured current and the gap. Same standard on the equation.
Done when a second person gets a nearby current from your written setup without asking you a question.
This week. Use a 9 volt battery and one resistor whose ohms are printed on it. Before you close the circuit, write current = voltage ÷ resistance, with the numbers filled in. Measure with a meter. Record the gap and whether you blame the resistor value, the battery, or the meter.
Log for this week. Date. Resistor value (Ω). Predicted current (A), written before closing. Measured current (A). Gap. Which part you blame. Who can rebuild the setup from this page.
Computer science
Write a specification in sentences, then a program that meets it. A classmate chooses an input you did not use. The log includes a script that reads a real file from the project, reports something you did not already know, and runs on a second file without an edit.
Cryptography is not a separate track. If that is your aim, stay on this project: the specification still comes first, and by grade 12 a classmate tries to break a piece you designed (a toy cipher, a password check, a signature, or an access rule) on your own system in a closed setting — not on a live network.
Done when the classmate’s input is in the log with the result the specification promised and the result the program produced.
This week. Specification, in sentences: the program reads a text file of one number per line, prints how many numbers it read, their sum, and the mean, and refuses a file that contains a word. Write that before you write the program. A classmate supplies a second file you have not opened. The log records what the specification promised and what the program printed.
Log for this week. Date. Specification sentences, written before any code. Your file’s count, sum, and mean. Classmate’s file name. What the specification promised for that file. What the program printed. Where they disagree.
Marine biology
Pick a site you can revisit. Write the method: where, when, and how many samples. Visit three times with that method. Any count or density keeps both sides of the equation balanced.
Done when a second person can repeat a fourth visit from the method alone.
This week. Pick one place you can walk to three times. Mark one square you can find again, about one step on a side. Count one kind of organism you can recognize, and write the feature you used to recognize it. Visit three times on three days. The method names the place, the square, the organism, and the count each day. Density is the count divided by the area of the square. Show that division as an equation with both sides named.
Log for this week. Place. How to find the square again. Organism and recognition feature. Day 1 date and count. Day 2 date and count. Day 3 date and count. Density equation with both sides named. Who could do visit 4 from this page alone.
Pre-med
Choose one mechanism from biology. Write the causal chain. For each link, write the observation that supports it, and mark which observations you have only from a summary. Any concentration or dosage arithmetic stays balanced on both sides.
Done when a stranger can point to the link whose evidence is weakest, and you can say what measurement would strengthen it.
This week. Explain why breathing gets faster during a run. Write the chain: muscles use more oxygen, carbon dioxide in the blood rises, sensors detect that rise, breathing rate increases. For each link, write the observation that supports it. Mark any link you only have from a summary. Name the measurement that would test the weakest link, such as a change in breathing when carbon dioxide changes and exercise does not.
Log for this week. Date. Four links in the chain. Observation for each link. Which links are summary-only. Weakest link. Measurement that would test it.
Pre-law
Take one short statute, rule, or contract clause and a one-page fact pattern that includes irrelevant facts. Write which facts the rule uses and what result follows. One page.
Done when someone who has not discussed the problem with you follows your writeup and reaches your result, or their miss shows a step you left to judgement. If the open step is a judgment call, name the choices (A/B) on the page so the reader can pick without asking you.
This week. Use this clause, and only this clause: “The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated.” Facts: Sam left a backpack on a city bus. Sam had eaten a sandwich at noon. The driver opened the backpack to look for a name. It was raining. Write one page on which facts the clause uses and what result follows. A reader who has not talked to you follows that page.
Log for this week. Date. Facts the clause uses. Facts the clause ignores. Result that follows. Reader’s name. Whether they reached your result without asking you.
PhD on-ramp
Write a question and this sentence: “I would drop this question if I saw ___.” Start a log. Another person must be able to carry out the next observation from the log without asking what you meant. The field may stay unnamed this year.
Done when that sentence and a followable method are both in the log.
This week. Write one question you can test with a count, for example whether more of one insect appear at your site after rain. Add the sentence “I would drop this question if three visits showed no difference I could count.” Write the method so a stranger can do the next visit: where, when, what to count, and where to write the number. The field can stay unnamed.
Log for this week. Date. Question. Drop-sentence. Where. When. What to count. Where to write the number. Field (may be blank). Who could do the next visit from this page.
Teacher guide
Grade 9 — teacher guide
One student, one track, one project. Do not assign a second project. The “this week” task in the lesson is the required start, not an example to skip.
Ladder. Rungs 1–8 for every track except pre-law. Pre-law does rung 1 and the memo.
What to cut. Renderings, extra clinical hours, mock-trial travel, and a second app. The log and the done bar in the lesson stay.
Admission. The log is the record. Do not build a separate activities list this year.
For Mechanical engineering:
Example of a finished week (numbers are made up; the student must measure). Date: 2026-09-12. Gap: 28 cm. Material: corrugated cardboard strip, ~3 cm wide. Predicted failure mass, before loading: 180 g. Measured failure mass: 245 g. Difference: +65 g. Weight: 0.245 kg × 9.8 m/s² = 2.40 N (both sides multiplied by 9.8). Who rebuilds the test: a classmate who was not in the room. Done when they get a failure in the same region from this page alone. A method trial for the rebuild bar lives in content/college-tracks/trials/me-week-1-method.md.
For Pre-law:
Example of a finished week (facts and result are for the teacher; the student must write their own). Date: 2026-09-12. Facts the clause uses: Sam left a backpack; the driver opened it. Facts ignored: sandwich at noon; rain. Result: opening the bag to look for a name is a search of an effect; on these facts the clause’s protection applies. Judgment fork written for the reader (do not ask the author): A = bag still Sam’s effect → protection applies; B = leaving it on the bus ends that security → protection does not. Reader: a classmate who has not discussed the problem. They pick A or B from the page alone. A first draft that names abandonment without an A/B choice fails that read.
For Electrical engineering:
Example of a finished week (numbers are made up; the student must measure). Date: 2026-09-12. Resistor: 470 Ω. Predicted current before closing: 9 V ÷ 470 Ω = 0.019 A. Measured: 0.017 A. Gap: −0.002 A. Blame: battery below 9 V under load. Rebuild: a classmate using only this page. A method trial for the rebuild bar lives in content/college-tracks/trials/ee-week-1-method.md.
For Computer science:
Example of a finished week (files are made up unless a trial folder exists; the student must run their own). Date: 2026-09-12. Specification written first. Own file: count 4, sum 10, mean 2.5. Classmate file: samples-b.txt. Specification promised: count, sum, mean, or refuse a word. Program printed: count 3, sum 9, mean 3.0. Disagreement: none for that file. Word-file test refused as specified. A completed trial with real files lives in content/college-tracks/trials/cs-week-1/.
For Marine biology:
Example of a finished week (counts are made up; the student must visit). Date: 2026-09-12. Place: north edge of the school field, oak drip line. Square: one step on a side, marked with two sticks. Organism: ants, counted when six legs and antennae are visible. Day 1: 12. Day 2: 9. Day 3: 14. Density day 1: 12 insects / 0.5 m² = 24 / m² (both sides named). Visit 4: a classmate using only this page.
For Pre-med:
Example of a finished week (observations are for the teacher; the student must write their own). Date: 2026-09-12. Chain: muscles use more O₂ → CO₂ in blood rises → sensors fire → breathing rate rises. Summary-only link: sensors fire (textbook). Weakest link: that one. Measurement that would test it: breathing rate when CO₂ rises at rest.
For PhD on-ramp:
Example of a finished week (question is made up; the student must choose their own). Date: 2026-09-12. Question: do more pill bugs appear under the board after rain than on a dry day. Drop-sentence: I would drop this if three visits showed no difference I could count. Method: lift the board with the red-clay brick on the west corner; wet = raining or soil under the board damp; dry = not raining and soil dry; count for 60 seconds; write date / wet-or-dry / count on the index card under the brick. Field: unnamed. Next visit: a stranger following this page. A completed trial lives in content/college-tracks/trials/phd-week-1.md.
