student who eat healthier will perform better

My Hypothesis is that students who eat healthier will perform better in school

Experiment would consist of 2 groups, the first  group  will be eat junk food. wile the second group  will be eat healthy food.

I would monitor them throughout the day and see witch students are stay focused better and do better in school

I would then be able to see the results that healthyer eating habits helps you function and focus better throughout the day.
