For my science fair project I am doing "Does temperature affect how high a ball bounces?" I did my expiriment (bouncing a softball, baseball, rubberball, golf ball, and tennis ball from 48 inches and measuring how high each bounces. I did this in several different conditions either after the balls had been in the freezer, fridge, heated stove, room temp.)I did this 3 times and my results made no sense. I thought when balls were heated they would bounce the highest due to expansion and that when balls were frozen they would bounce lower due to contraction, but my results really don't support that, or any type of pattern (Yes, I did do the expiriment 3 times, but none of the results show a pattern at all really this is the most recent time I tried it, and I was most careful to do everything correctly and get the right measurments this time): Frozen- Baseball-16 Softball-21 Golfball-35 Rubberball-37 Tennisball-10 Fridge- Baseball-15 Softball-19 Golfball- 39 Rubberball- 36 Tennisball- 24 Room Temp- Baseball-15 Softball-19 Golfball-39 Rubberball-36 Tennisball-27 Heated- Baseball-17 Softball-19 Golfball-37 Rubberball-34 Tennisball-28 Please help me make sense of this and provide me with any information possible. Thank you very much.
Re: Wouldn't expansion and contraction help me out?
