When I was in 6th grade and I had to do a science experiment I did one on heat and bouncing balls.
What I was trying to find out was how temperature affected the height at which a ball bounced. I bought 9 of the same rubber balls at the local sports store. I then put 3 of them in my freezer, left three out alone, and prepared the last 3 to be heated in boiling water.
I got a measuring stick and then took the balls and bounced them at the different temperatures. I had three different balls of each temperature so that I could do a few different tests and get a good average of results.
When they bounced, I measured where the tip of the ball got to on the stick and then compared my results!
For other ideas, look through here:
