My science fair project is basically making a game. In this game you pick up diamonds, and the objective is to pick all 10 of them up in the least amount of time. My theory is that teens will have lesser time than adults, but i dont know how to put this in a 'physics/science' way. I also have to find articles proving this, but i dont know what keyword to search for! If anyone can be so kind as to suggest how i can turn this idea into a good topic, i will appreciate it! thanks in advance.
