Dimitra's Science Fair Project

"Left Out Or Right On"

Are you Left out, or right on? 

1) Problem: How does one’s handedness affect foot, eye, and ear preference? 

2) Hypothesis: I think right handed people will close  there right eye, kick with there right foot and use there left ear. I think left handed people will close there left eye, kick with there left foot, and use there left ear. 

3) Materials:10 right handed volunteers

                 10 left handed volunteers

                  Soccer ball

                  Cardboard tube     

                  Toy bow and arrow set

                   Small cardboard    box

                   Macaroni

                   Tape

 4) Procedure:

Testing foot preference 

      1) I had each volunteer stand in front of a soccer ball. I asked them to kick it and I recorded which foot each volunteer  used to kick the ball.

      2) I had each volunteer stand at the bottom of a staircase. I asked them to climb the stairs and I recorded which foot they used to begin there climb.

Testing for eye preference 

      1) I asked each volunteer to look through a cardboard tube. I recorded which eye they used.

      2) I asked each volunteer to shoot the bow and arrow at an object across the room. I recorded which eye was left open.

Testing for ear preference 

      1) I asked each volunteer to put there ear up to a wall to see if they can hear what’s going on in the next room. I recorded which ear they put up to the wall.

      2) I asked each volunteer to shake a box full of macaroni and I asked them what’s inside the box. I recorded which ear they held the box up to.

 RF~ Right foot       LF~ Left foot

RE~ Right eye        LE~ Left eye

RER~ Right ear      LER~ Left ear  

LR~ Left or Right 

Table of results # 2 

 5) Conclusion:  Most left-handed people use their left foot, left eye, and left ear. Most right-handed people used their right foot, right eye, and right ear. This proved that my hypothesis was correct. 

* I noticed that a lot of people could use both feet for kicking the ball. Not a lot of people could use both right and left for their eye and ear testing. 

* A lot of the left-handed adults I tested, used there right foot, eye, and ear more then the children who were left- handed. 

Project  Summary

How did I come up with my project idea? 

My mom and I were searching through books and we thought that this project looked interesting. I was really keen on doing this as it was something I knew that I would enjoy and learned from.

 What did I learn from my experiment?

 I learned that a lot of right-handed people use there right foot, eye, and ear and a lot of left-handed people left foot, eye, and ear.

 How close were my hypothesis and conclusion?

 I guessed that left-handed people would use their left foot, eye, and ear and right-handed people would use their right foot, eye, and ear and I was right.

 Did I learn anything new from my project?

 I learned that some left-handed people and some right-handed people could use both feet to kick the ball but they couldn’t use both right and left ear or eye.

 What was the most interesting part of my project?

The most interesting part of my project was when my hypothesis and conclusion matched. I also enjoyed  testing people. It was very interesting to observe people doing the tasks that were part of my experiment as I found myself predicting what the results would be.
