Body Dominance Across Hand, Foot, Eye, and Ear
Easy
Does everyone use the same side of their body for everything? About 90% of people are right-handed. But they may not favor their right foot or right eye.
You test a group of people with simple tasks. For hands, you watch which one they write with. For feet, you see which one kicks a ball first. For eyes, you check which one they look through a tube with.
You record each result and look for patterns. Some people are right-sided for everything. Others use a mix of right and left across different body parts.
Hypothesis
The hypothesis is that people have a dominant hand, foot, eye and ear.
Science Concepts Learned
Laterality
Most people prefer one side of their body. About 90% of people are right-handed. But that preference may not carry over to feet or eyes. You can test which hand writes and which foot kicks. Some people favor different sides for different tasks.
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.

See what’s includedResults
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.

Have you ever wondered if you could write as well with your non-dominant hand as you can with your dominant hand? In this video, you can put your writing skills to the test and see how well you can write with both hands. Get ready to discover a new side of your brain!
