Science Experiments

Question: Some easy science experiments?

I was wondering if someone had some experiments I could do for my project. Some that people had were “Does different video games affect pulse rate” or ” Does different brand cake affect how tall it is after baked” or ” Does size of ball affect how high it bounces”

I have no idea what to do for my project. I was going to do if different brand batteries affect how long they last, but I would have to buy a lot of batteries and waste them.
I’m in 8th grade and 14 years old. =]

Answer: I suggest trying to find the absorbency of three or more different brands of paper towels. That’s what my friends and I did for a science experiment, and it took us 15 minutes top XD

Unless you want something a little more challenging, like “Does stress make you eat more” where you get a group of people, set a plate of cookies or something in front of them, give them a really easy puzzle to do, and record how many cookies each person eats. Do the same thing again only with a harder puzzle. My friends and I were going to do this but our teacher didn’t approve -for a reasons we have yet to know…>.><.<-
