General Psychology Science Fair Project

Dominant Hand, Foot, Eye and Ear

Dominant Hand, Foot, Eye and Ear | Science Fair Projects | STEM Projects
Have you ever thought about which side of your body you use more often? This might surprise you, but most people have a dominant side, meaning they use one hand, foot, eye, and ear more often than the other. By discovering which side you favor, you can learn more about yourself and maybe even improve your skills and abilities!


The hypothesis is that people have a dominant hand, foot, eye and ear.

Method & Materials

You will observe people to see which hand they use to write, cut, throw a ball, eat, and pick up a cup. You will also observe which foot they use to kick a ball, step up a stair, and step on a coin. Plus, you will observe which eye they use to look through a tube and sight a distant object, and which ear they use to listen to a whisper and a sound from a box.
You will need a pen or pencil and paper, scissors, a ball, a cup with water, a fork or spoon and food, a coin, a paper or cardboard tube, and paper with a small hole.


After observing people to see which hand, foot, eye and ear they use the most, you can conclude that people have a dominant hand, foot, eye and ear. An interesting observation is that about 90% of the population is right-handed.

Why do this project?

This science project is interesting and unique because it helps you find out which hand, foot, eye and ear you use the most.

Also Consider

Experiment variations to consider include testing people with different age groups or using different activities to test for dominance.
