balls first bounce

Equipment: metre ruler-tennis ball-retort stand-boos head and clamp 

Aim: 

To see how high the tennis ball will bounce on its first bounce from different height

Hypothesis 

I think the ball will not go that high because when you drop it  won't go how far you bounced it from if you drop high it will go about 3 meters high or more 

Method 

get a ball
to use for your experiment

go somewhere high
to get height to see what it does

grab a retort stand and a clamp
   to get the ball

get a ruler one metre
 to measure how high the bounce is

Independent. the height we drop it from 

Dependent. the measurement of the first bounce.

Control.use the same ball through the whole experiment
