My son once did an experiment to test the rebound effect of baseballs at different temperatures.

A dozen room temp balls, a dozen balls in the freezer, and a dozen balls in the oven for two hours at 200 degrees.

Release them all from the same height onto a concrete floor, and measure the height of the bounce. Best way to measure is to videotape the bounces against a background with a measured grid.

Then take the data and plot the average bounce for each temperature, the variation, std dev, etc.

Sure A for an 8th grade project.
