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.

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?
How would I improve the experiment in the future, any errors?

Your data mostly refutes your hypothesis because the ball at 40 degrees Celsius bounced higher than the one at 0 degrees Celsius, but they both had the same average bounce height.

To improve the experiment, you could test more balls at different temperatures and repeat the drops multiple times to ensure accuracy in the results.

One possible error could be how the temperatures were measured or if the balls were dropped consistently.

In conclusion, the temperature of a ball does affect how high it bounces, but more testing is needed to get clearer results and understand the relationship better.
