Hi Hanjan,

This sounds like a really great project!

Here is information from the Science Buddies website on variables for your science project:

Your independent variable is the level of vision in your test subject. The dependent variable is the hearing measurement that you have made for each test subject. Do you have results that you can graph?

Do you have results of vision tests for each subject? Do you have of method for measuring hearing?

Be sure and read the information from the Science Buddies website on doing projects that involve working with human subjects. It’s very important to follow all of the rules so your project will not be disqualified during judging.
