STEM Fair ProjectProject title Which Ball Bounces the Highest?

Class Project | Mr. Hart| Northview

Statement of the ProblemStudents will investigate to see which ball bounces the highest: Basketball, Dodge ball, Playground Ball, and Kickball.

Project Overview• Students will drop four different balls at

the height of 91 centimeters to see which ball bounces the highest.

• Each type of ball will be dropped four times, and the height of which it bounced will be recorded.

Research• Summarize your research here in three to

five bullet points:

• Balls bounce with the combination of gravity and energy.

• Gravity is the force that pulls everything on Earth towards the center of the Earth.

• Gravity is what pulls the falling ball towards the ground.

• As the ball falls, it gains energy from its environment.

Variables• Controlled variables: The height at

which each ball is bounced

• Independent variable: The type of ball

• Dependent variable: The height that each type of ball bounced, and its recorded data…

Hypothesis• The basketball will bounced the highest

since it is used to dribble, bounce, and shoot in basketball competitions. The basket ball is also known to have bounced off backboards, other players, and out of the game.

Materials• Meter stick

• Yellow Dodge ball

• Green Playground ball

• Red Kickball

Procedure1. Student will hold meter stick touching

the ground with the beginning of the number readings touching the ground.

2. Students will drop each of the type of balls from the top of the meter stick (four times), and record the results of the height that each ball bounced off the ground.

Data/Observations• Heights that each ball bounced:
