Science teachers require hard scientific study based and written according to scientific method. everytime. For science in addition to your survey you want to focus on the brain. Which half (hemisphere) controls what hand etc.

Here are some resources to get you started. Some are a “meaty” heavy science content others fun. Please do not plagerise any this is meant to help you. Site your sources.

This should help you begin to understand the science behind your fair idea. Good luck. The first source (Indiana U)about datbases is actual scientific journal article titles your librarian can help you locate. You teachers want solid scientific based sources not just anything. Again do your own work nor plagerism…teachers can often tell… really….

Good luck
