Roll a solid cylinder and a hollow tube down the same ramp and use the winner to test a prediction from rotational physics.
Predict and measure the speed ratio of a solid cylinder and a hollow cylinder rolling down a ramp, using moment of inertia.
Record how a cup of hot water cools, fit an exponential model, and use it to predict the temperature at a later time.
