Science Buddies: "Ask an Expert"

Can anyone give me some facts that relate to my topic? My topic was "how does the temperature a ball affect how high it will bounce." Please help me, I only need 20 facts, this is my science fair project. So please help, Thank You!!!

Hi Jonny,
Temperature and pressure are related through what are known as the "Gas Laws".

The pressure inside a ball will affect how the ball bounces. You need to determine how the pressure affects the ball's bounce. My guess is that the pressure inside the ball will affect the elastic behavior of the ball and therefor the bounce of the ball. Try to find some facts on the effects of elasticity on the ball's bounce. My guess is that the more elastic the ball the more bounce the ball has.

Good Luck,
John Furman

Thank for your help! But I need 20 facts about my topic "how does the temperature of a ball affect how high it will bounce. Thank you!

Please don't start multiple threads. Experts only check the forum once a day or so, posting more frequently won't get a faster answer, and can even slow it down.

You said you had 6 facts. What are they? Have you learned other things in your research that you don't think are facts? Maybe they are... The more you post information you post, the more helpful people can be.

Here are some thought-
Temperature can effect how "springy" a plastic is. Think of chewing gum. If you drink cold soda with gum in your mouth, it gets hard. If you drink hot chocolate, it gets soft. Not all plastics behave the same way with temperature. The temperature changes the properties of the plastic. If you know what the ball is made of, you look at how that type of plastic changes with temperature.

[This would several facts. 1) The material the ball is made of 2) The effect of temperature on that material 3+) You could learn some facts about what a 'plastic' or 'polymer' is]

Similarly, the gas law could generate several facts. Look it up!

Hope this helps.
