I\\\'m doing a science fair project that is Does a tennis ball bounce higher on wood floor or cardboard. I already know that it will bounce higher on wood floor, but i have no way to prove it.

I\'m not sure I understand what you mean. You can drop the ball from the same height on either surface and see which way bounces higher. You can repeat the procedure a few times to check. What better proof could you get?
