NEED SCIENCE FAIR HELP!!! Does anyone have any experimental ideas for a science fair on high school level?

Question

I need help on ideas for my science fair this school year. We have to construct our own experiment which is to be reflective of the high school level. I'M NOT A VERY CREATIVE PERSON SO I NEED HELP!!!! What we have to do is read articles and base our experiments off of those articles. I need help thanks! Any ideas will do from bacteria to food! Thanks!

Answer 1

An easy one is to prove the speed of gravity. You drop a series of bouncy balls from the same height or different height or different objects, measuring the distance and the fall time for each trial. The answer is 9.80m/s^2.

You could do a tough one related to chemistry. Like calculate the # of moles of a substance that are released from a compound when heated. It hurts to think about it, huh?

You could also test the pH of different kinds of water. Pure water is 7, but what is the local tap's pH? Compare to bottled water.

You could also do some research on different kinds of bacteria in.. say milk. Then observe the bacteria in unpasterized milk. Compared to pasterized. What fun!

You could figure out at what altitude your hometown is simply by boiling water & seeing @ what temp. it boils at, using multiple themometers for accuracy. In Wytheville, VA, water boils at 98 degrees C b/c  of the high altitude.

Answer 2

With a video camera and editing software, you can measure the speed of sound. Have a friend set off a firecracker at one end of a large field or stadium while you film it. The difference in time between the flash and the bang, as measure by the number of frames, will give you the speed of sound.

Otherwise, here's an interesting site with thousands of DIY projects that might give you ideas:
