Left-Handedness: A Science Project

Easy
Left-Handedness: A Science Project | Science Fair Projects | STEM Projects
Have you ever wondered how many people are left-handed? This science project will help you find out! You'll observe people writing their names and record the number of left-handed people in each class. Then, you'll calculate the percentage of left-handed people in the school.

Hypothesis

The hypothesis is that left-handed persons will form less than 10% of the total number of persons surveyed.

Method & Materials

You will visit two classes each day and ask the students to write their names in a registration book. You will observe which hand they use to write and record it in a register. You will repeat this with the remaining five classes over three days.
You will need a registration book for students to write their names, a pen, an authorization letter from the school principal, and a register of all the student names in each class.

Results

After observing the students, it was found that the total percentage of left-handed students among the 12 year olds in the school was only 6.3%. This proves that the hypothesis was correct.

Why do this project?

This science project is interesting because it shows how left-handed people are in the minority. It also shows how the brain works differently in left-handed people.

Also Consider

Consider conducting a survey to find out how many left-handed people kick a ball with their left foot. Also, consider conducting a survey on how many people can fold their tongue.
