Left-Handed Ambidexterity | Science Fair Projects | STEM Projects
Are you left-handed? Do you have the ability to use both hands equally well? Let's find out in this science project! We'll be testing 10 participants to see if left-handers have a higher level of ambidexterity than right-handers. We'll measure the time taken to complete two tasks using both hands.

Hypothesis

The hypothesis is that there are more ambidextrous left-handers than right-handers.

Method & Materials

You will test 10 participants by giving them two tasks to complete. The first task is to cut out objects from a piece of paper using one hand. The second task is to fix a nut to a bolt using one hand. The time taken to complete the tasks will be measured using a stopwatch.
You will need 5 left-handed participants, 5 right-handed participants, 10 scissors, 20 copies of paper with 5 objects drawn, 10 bolts and nuts, and 1 stopwatch.

Results

The results showed that the left-handed participants demonstrated a higher level of ambidexterity compared to the right-handers. The hypothesis that there are more ambidextrous left-handers than right-handers was proven to be true.

Why do this project?

This science project is interesting because it shows that left-handed people have an advantage when it comes to ambidexterity. It also shows that ambidexterity can be learned with practice.

Also Consider

To improve the reliability and accuracy of the results, a larger sample of participants should be used. This science project can also be repeated to observe if the level of ambidexterity is affected by the age of a person.
