What type of ball bounces the highest?
Abstract
The purpose of this experiment was to determine which type of ball bounced the
highest. Three balls were tested for my experiment: a basketball, a golf ball, and a
tennis ball. My hypothesis was that the basketball would bounce the highest. I needed to
find out which balls I would use and which ball would bounce back the highest in my
experiment. Each ball was bounced from 2 feet, 3 feet, and 4 feet to see which one
would bounce back. When I did my experiment, I dropped the balls from the same
heights, dropped them on the same surface, and dropped them in the same area to
make sure I wasn’t on a slant. In summary, the golf ball bounced the highest rather than
the tennis ball or basketball.

Hypothesis
My hypothesis is that the basketball will bounce the highest.
Introduction
The purpose of my experiment is to find out what type of ball bounces th highest. I chose this as my science fair project because I have always wondered about this experiment. I also thought that this is experiment would be fun and help me to answer my curiosity.
Variables
The independent variable is what type of balls I am going to bounce: a basketball, a tennis ball, and a golf ball. The dependent variable is how high the ball bounces. The controlled variable/constants are dropping the balls at the same heights, dropping the balls on the same surface, and standing in the same area while measuring and dropping the balls.
Procedures
1. Measure to 2ft on a flat surface with your measuring tape.
2. Drop the basketball from 2ft high and record how high it bounces back.
3. Drop the tennis ball from 2ft and record how high it bounces back.
4. Drop the golf ball from 2ft high and record how high it bounces back.
5. Measure to 3ft on a flat surface with your measuring tape.
6. Drop the basketball from 3ft and record how high it bounces back.
7. Drop the tennis ball from 3ft and record how high it bounces back.
8. Drop the golf ball from 3 ft and record how high it bounces back.
9. Measure to 4ft on a flat surface with your measuring tape.
10. Drop the basketball from 4ft and record how high it bounces back.
11. Drop the tennis ball from 4ft and record how high it bounces back.
12. Drop the golf ball from 4ft high and record how high it bounces back.
13. Take pictures of each ball.
14. Record data and observations.

Materials
1 basketball
1 golf ball
1 tennis ball
1 tape measure

Conclusions

What type of ball bounces the highest? My hypothesis, I think the basketball will bounce
the highest, was incorrect. If I were to do this experiment again, I would look at the
same experiment that other people did and how they actually did their experiment.
Then I would compare their experiment to mine. While doing my experiment, I learned
that a golf ball bounces higher than a basketball and a tennis ball. I also learned how to
measure the height of the balls while they are bouncing and how to test and measure
for a science fair experiment. This is what I learned from my science fair experiment.

Results
In my science fair experiment, the golf ball overall was the ball that bounced the highest.
At 2ft, the basketball bounced 15 inches, the tennis ball bounced 12 inches, and the golf
ball bounced 6 inches. At 3ft, the basketball bounced 20 inches, the tennis ball bounced
15 inches, and the golf ball bounced 26 inches. At 4ft, the basketball bounced 25
inches, the tennis ball bounced 18 inches, and the golf ball bounced 36 inches.
