Science Fair

This term everyone in year 7/8 syndicate are doing a science fair. My question is ' Does Caffeine Effect Your Hand/Eye Coordination?' I'm on task and have completed my experiment. 

1.6 people each had a turn of throwing 12 balls into a hula-hoop, to see how many they could get in. 

2.Next they drank a caffeined drink.

3. They waited 15 minuets. 

4.Finally they each repeated the first step to see if they improved their score.

A majority of the people did improve there score.

 But I had a controlled group.

They did the same experiment but instead they drank Raro not Coke. Because Raro does not have caffeine in it they were not supposed to improve their score.

And most people didn't

It was a lot of fun.
