In this project, I set out to test the impact a surface has on the bounce of a ball. The three surfaces that I tested were cement, wood, and turf. I used a wooden plank to measure the heights and marked it every 5 centimeters up to 150 centimeters. After this step was done, one at a time I bounced the balls, and while I was doing this I used a recording device so that I could go back and see the highest point of each bounce. My hypothesis was that basketball would have the highest bounce on all surface and that the wood surface would make the balls bounce the highest. While I was experimenting I observed that the golf ball had a higher bounce than I had initially thought, especially on the cement surface. The results supported one of my
