Bouncy Balls

Aim

The purpose of my investigation is to find out how high a ball can bounce at a certain height.

Equipment

-Golf ball

-1m Ruler

-Clamp

-Devices (That is able to record)

Hypothesis

The higher the ball drop the higher bounce but not higher from where you drop the ball.

Method

-Get the equipment needed (ball, ruler, stand with boss head, papers to put your data on and camera)

-Try out my investigation 3 times at 5 certain height while my camera is recording in slow motion.

-Records my data.

-Put in a graph 

Finish off experiment by blogging it

Key Variables

The Dependent Variable -The height of the ball bounces

The Independent Variable -The height of the ball

Control Variables-Surface of where you drop the ball

                            -The type of ball you use

Drop Height	Height	Of	First	Bounce
	Trial 1	Trial 2	Trial 3	Average

0.2 (m)	9 (cm)	14 (cm)	13.5 (cm)	14 (cm)
0.4 (m)	27 (cm)	27 (cm)	27 (cm)	27 (cm)
0.6 (m)	34 (cm)	33 (cm)	32 (cm)	34 (cm)
0.8 (m)	43 (cm)	44 (cm)	40 (cm)	44 (cm)
1 (m)s	52.5 (cm)	50 (cm)	51 (cm)	52.5 (cm)

Conclusion

My hypothesis was correct  "The higher the ball drop the higher bounce but not higher from where you drop the ball.''
