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?

GPT-4o mini · Answer

Your hypothesis was that the warmer the ball, the higher it will bounce. Let's analyze your data in light of this hypothesis:

Ball with One Stripe (0 °C):
- Average Bounce Height: 0 cm
- This indicates that the ball did not bounce at all, which refutes your hypothesis.
Ball with Two Stripes (40 °C):
- Average Bounce Height: 65 cm
- This supports your hypothesis, as the ball was at a warmer temperature and did bounce higher.
Ball with No Stripes (20 °C):
- Average Bounce Height: 65 cm
- This result is the same as the ball with two stripes, but since this ball was at a cooler temperature than the one at 40 °C, it does not fully support your hypothesis.

In summary, while one ball did bounce at the higher temperature (40 °C) supporting your hypothesis, the ball at 0 °C did not bounce at all, which contradicts your expectation that a warmer temperature correlates with a higher bounce. Additionally, the ball at 20 °C did not show a higher bounce than the one at 40 °C.

Overall, your data partially supports your hypothesis, but it also includes results that significantly refute it, particularly with the ball that had one stripe. This suggests that other factors, such as the material properties of the balls or possible inconsistencies in experimental conditions, might also affect the bounce height.
