Greetings, I am delighted to share with you the details of our science class experiment. In this experiment, we aimed to determine how high three different types of balls bounce on two different surfaces, namely, concrete and carpet.

Our experiment made use of a ping pong ball, an All Blacks yellow ball, and a tiny football. We hypothesized that the ping pong ball would bounce the highest on concrete, while the All Blacks ball would bounce the highest on carpet. We selected these balls based on their varying elasticity and springiness.
To conduct the experiment, we used specific equipment, including a 1-meter ruler, a pen or pencil, an eraser, and a friend to assist us in checking our measurements or holding the ruler or dropping the ball. We carefully selected a space that had a carpet on the ground and another space that had a ground or surface made of concrete.
Our method was precise and methodical. We held each ball right next to the 0 cm mark on our 1-meter ruler and dropped it without applying any extra pressure or force. We repeated this process three times for each ball on both surfaces, and we recorded the highest height that each ball bounced to on our piece of paper.
After conducting the experiment, we compared the results and determined which ball bounced the highest on each surface. Our findings were fascinating, and I am thrilled to present them to you in a scientific report. Additionally, we have captured some short videos and photos of us conducting the experiment.
I hope you find this information detailed and informative!
