The Super Ball Project

QUESTION•Does a surface effect the bounce of a super ball?

Purpose• The purpose of my investigation is

to determine if a surface effects the bounce of a super ball. This is important to know because if you play catch and there are two different surfaces between you, might need to know how high it goes to catch the ball.

Hypothesis• I hypothesize that a super balls

bounce will be effected by different surfaces. I believe this because I think the hardness of the surface may make it fly if its hard and a surface that is soft may make it do a little bounce.

Procedure

MaterialsSuper ballTape measureSide walkRoadRecording paper

VariablesManiputed: the surfaceResponing: how high the ball goes

Constant: Method of measuring how high the ball goes and the height the ball is dropped from it

Directions1 Gather materials2 Go to the sidewalk3 Hold the ball 1 m above ground4 Drop the ball5 Measure how high the ball went. Record.6 Go to the road7 Hold the ball 1 m above ground8 Measure how high the ball went. Record.9 Repeat 1- 8 four more times

GRAPH

CONCLUSIONMy hypothesis was correct. Surfaces do effect the bounce of a super ball. The average bounce height of the sidewalk was 60 cm. The average bounce height of the road was 58.42 cm. If I would changed one thing I would change the surfaces because the road is not safe.
