Why does a rubber ball bounce?.

The polymer chains sort of relax and then take their shape once again. If polymers are tighter together, the ball bounces higher. Knowing this, you might be able to predict what the polymers are like in, say, a basketball, a ping pong ball, or a racquetball.

But what about a steel ball? It has different polymers than a rubber ball. Believe it or not, a steel ball actually bounces higher than a rubber ball. When it hits the ground, the steel snaps back faster. The steel is better at storing energy, which helps give it a lot of bounce power. You can investigate bounciness with an activity at home. Here are some instructions to make your very own bouncy ball. How high will your bouncy ball go? What happens if you warm it up?

What happens if you cool it down? An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment. If you manipulated the volume and measured the pressure as a result, the volume would be the independent variable and the pressure would be the dependent variable because the pressure was dependent on the volume.
