Question

I am doing an experiment with testing how high a ball with bounce when the temp changes. I think the warmer the ball the higher it will bounce. I will drop them from 70 centimeters. 3 balls one with one stripe one with two and one with none. I will place a ball with 1 in the freezer overnight, the reached a temp of 0 degrees Celsius. Another ball with 2 stripes in the oven at the temp of 40 degrees Celsius. The last ball with no stripes I left in a room at the temp of 20 degrees Celsius overnight.
Ball with one stripe had an average bounce height 0 cm. Ball with two stripes had an average bounce height 65 cm.
Ball with no stripes had an average bounce height of 65 cm.
How did my data support or refute my hypothesis?
One sentence. For an 8th grader

Answer 1

Your data refutes your hypothesis because the ball with one stripe, which was the coldest, did not bounce at all, while the other two balls at higher temperatures bounced the same height.
