Snowball Earth: why a dimmer sun freezes the planet and today's cannot thaw it

Afterwards you can explain the ice-albedo feedback, a tipping point, and hysteresis, and compute them with a one-dimensional energy balance model.

Plucked string harmonics: why a pluck at a third has no third harmonic

Afterwards you can expand any string shape in a Fourier series, follow a pluck's kinks with d'Alembert, and predict its missing harmonics and its brightness.
