Ok so it’s science fair time. At my school’s science fair, you don’t build something and present it. You have to test something and present it. I’d love to do something yoyo related but it seems as though there are too many variables. There can only be one variable which I can manipulate and I have to observe how that variable causes something else to happen.
The independent variable is the one I shall manipulate. The dependent variable is what the independent variable affects. After I find my question I must present a hypotheses in an if/then statement, or a conditional statement if you will. (i.e. If I change the response pad in a yoyo from IrPads to Flowable Silicone, then the yoyo will spin longer.) The only issue is that I don't know how to keep each throw under the same exact power.
