STEM FAIR PROJECT
Project title Which Ball Bounces the Highest?
Class Project | Mr. Hart| Northview
STATEMENT OF THE PROBLEM
Students 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
• Basketball
• Yellow Dodge ball
• Green Playground ball
• Red Kickball
PROCEDURE
1. 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:
Type of Ball
Basketball
Dodge ball
Trial 1 Trial 2 Trial 3 Trial 4
50cm
55cm 49cm 56cm
30cm 37cm 34cm 36cm
Playground ball 56cm 61cm 56cm 54cm
Kickball
50cm 48cm 34cm 44cm
CONCLUSION
• Based on the data showing each type of ball and the height that each
ball bounced, the playground ball bounced the highest with trial one
showing 56cm, trial two – 61cm, trial three-56cm, and trial four-54
cm. The playground ball had the highest average that the ball
bounced.
