Can someone give me a few good science fair topics?

Question

I have to do a science fair project for school and I'm not quite sure what topic I want to do. The only thing is I have to be able to do an experiment...so no topics dealing with outer space or the inside of the Earth or anything else that I wouldn't be able to experiment on.

Answer 1

A successful topic I did once was static electricity. The experiment was to find out what kind of material would create the most static electricity when rubbed on a balloon. I think i tested taffeta, fleece, a sheet of plastic, a jar opener and probably something else that i forgot.

Anyway, you can use any materials you choose.

The way I tested it was to rub the material on a freshly blown balloon and then count the number of paper hole punches the balloon picked up after that. It was an extremely effective method.

I almost got the best in show award when I did this experiment (but didn't because I was too lazy to rerun the experiment before the district science fair thing to collect another round of data)

It's a great experiment because it's fun to research (if you're doing a research paper in addition?) and the experiment itself won't cost you a bunch of money or time.

P.S. Sorry for the wordy answer. :)

Answer 2

The focus now is on energy. Show a study of battery life vs battery weight for a given electrical load. The data needs to be corrected for voltage level. For example: report time to 3/4, half, 1/4  charge. You need to collect a few diverse battery styles for your experiments. Also, test at various temps: RT, cold condition, hot condition.

Perhaps some battery suppliers can give you some samples for your testing and reporting.

Answer 3

Good for you, look outside the box aside from volcanos and Earth's plate tectonics ;) My advice would be looking into creating a model for alternative energy or solar cooking...check this out:

Here's where you can find this and other ranges for science fair experiments.  Look into it, have fun, and good luck!
