Experiment Title: Bouncy ball. Carpet and Floor.
What was the purpose of your experiment? Provide a brief description of what you were hoping to learn, discover, or study.: I was hoping to learn how much higher the ball bounced on the floor than on the carpet.
What was your hypothesis?: That it would bounce a third higher than the carpet on the floor.
What materials did you use in your experiment? List them all.: Bouncy ball, floor, carpet, measuring tape, another person.
What procedure was followed? Provide a brief description of the steps you followed during your experiment.: I had the other person hold the measuring tape in place. I dropped the ball on the floor than observed how high it bounced. Then I repeated on the carpet.
What were the results of your experiment?: The one on the floor was only a bit, three inches, away from being exactly a third.
What is your conclusion after conducting the experiment? Was your hypothesis correct or incorrect?: My hypothesis was correct. It was about a third more. My conclusion is that the bouncy ball went about one third higher on the floor than it did on the carpet.
Spend a few minutes learning about the scientific principles involved in your experiment. Write 3-4 sentences about what you learned and how it relates to your experiment.: Gravity helps them go down at different times. Also, the carpet is a different type of surface. It makes it so that it doesn’t have the bounce that it does on a hard surface.
