Introduce the idea of acceleration as rate of change of velocity, using timers, wheels, inclined planes, calculators. Students roll balls down inclined planes and plot graphs of the measured positions and times. The size of errors is also discussed. Oscillator frequency and distance between nodes are measured, from which wavelength and velocity are then deduced and tabulated. Thermodynamics of gases and liquids, in particular Boyle's law, using a plunger to change the volume of a chamber and a pressure gauge to see the effect, and Charles's law, using hot plates, beakers, buckets with ice.
Students make ice cream using liquid nitrogen.
Ray optics, how curved mirrors and half-silvered mirrors work, making a pinhole camera and taking pictures with it. From measurements of distance, time, and mass, students can figure out the velocity and the momentum of each cart and show that total linear momentum is conserved in a collision.
