Milestone map
4 milestones
Oscillators, damping and resonance
4 weeks (about 12 hrs/week)
Work through 8.03SC Part I lectures 1–6 and read Volume 1 chapter 15. Then solve the odd-numbered problems of chapter 15 and the 8.03SC Part I problem sets. Self-check: University Physics Volume 1, Answer Key, chapter 15.
Proof required
Link the public repo with the odd-numbered problems of chapter 15 and the 8.03SC Part I problem sets written up (a typeset PDF, LaTeX source or notebook), and show the self-check: which answers matched and how you fixed the ones that did not.

Electromagnetic waves
4 weeks (about 12 hrs/week)
Work through 8.03SC Part II. Then solve the Part II problem sets, then a practice exam done timed. Self-check: MIT 8.03SC practice exams with solutions.
Proof required
Link the public repo with the Part II problem sets, then a practice exam done timed written up (a typeset PDF, LaTeX source or notebook), and show the self-check: which answers matched and how you fixed the ones that did not.

Measure the speed of sound in a tube
4 weeks (about 12 hrs/week)
Make a measurement of the speed of sound from the resonances of a tube (a cardboard tube or a plastic pipe), using a free phone tone generator or spectrum app. Find at least three resonant frequencies, measure the tube's length and radius, add 0.6 × radius for each open end, and fit frequency against mode number (a tube closed at one end has only odd modes). Safety: nothing with mains power, no laser above class 2 (read the label, never point it at an eye), no radioactive material, and no pressure or heat that can hurt. Under 18? Use the simulation or open-data route instead, or do it with an adult present. Keep the tone quiet and never hold the speaker against your ear. This set-up is safe at any age: a tube, a phone and a ruler.
Proof required
Link the public repo with the method, raw measurements, a photo of the set-up (and the laser's class label, if one is used), the analysis and the result, the result with its uncertainty, and a README that says what you did and what limits the result.
