Senses - Eyes on the Ball Experiment
 
Catching a ball

Materials you will need:

• Ball
• Blind fold/eye patch
• A couple friends

 

 
 
Steps

Here is a fun test for you!

How well do you think you are at catching a ball?

When you catch a ball you have to judge the speed and position of the ball coming at you. This test needs to be performed in an open area (preferably outside).

Ask these questions to your friend:

    1.)  Do you think it will make any difference catching a ball with one eye closed? Write down your prediction.__________________________________________
    2.)  Do you think it will make any difference which eye is closed? Write down your prediction.__________________________________________________

    3.)  Have your first friend stand around 3 feet away from you.

    4.)) Throw the ball underhand to your friend and record the number of times s/he catches the ball out of 20 throws. (you can use the chart below to help).

    5.)  Next, place the blind fold or eye patch over the left eye of your friend and throw the ball underhand to your friend and record the number of times s/he catches the ball out of 20 throws.

    6.)  Now place the blind fold or eye patch over the right eye of the same friend and throw the ball underhand to your friend and record the number of times s/he catches the ball out of 20 throws.

In the table below record the number of catches out of 20 throws.
