A question you need to answer for yourself: are you just trying to complete an assignment, or are you actually trying to win a science fair?

If you're just trying to complete an assignment, there are lots of projects on the web, one of which Jack A Lopez mentioned.  Pick one that's easy, build it, get your grade.

OTOH if you want to win a proper science fair, you have to do what scientists actually DO... which is "provide new knowledge".  Which is done as Kelseymh says; hypothesis-test-repeat.  Many years ago I judged a regional fair that was won by a young woman who had studied (believe it or not) the flammability of different types of dryer lint.  She won because: she had a genuine interest in what she was doing; she had done rigorous studies over a two-year period; her conclusions were fully justified with proper statistics.

At many science fairs, the project that wins is not the showiest, not the prettiest, not even the most ingenious.  It's the process, not the product.  It's the one that showed that the winner knew how science is done----and did it.

So:  if you're into winning, learn how science is really done.  Then find something you're truly interested in, and do science.

The easiest "working model of science" for a science fair would be hypothesis-test-repeat.
I always liked the ball-rolling-down-ramp ballistics demo, and I have described this demo previously, here:

Science fair?

Try a Van der Graaff generator running an electrostatic motor.
There's a neat one in the current edition of Make magazine
Which, the generator or the motor?
Sorry, VdG

Start investigating how your iris stops-down under IR LED light from a safe
remote control while you look into a mirror in a darkened room.
