You could make a potato clock or you could test algae and see how they react to different chemicals.  Volcanoes are cool but predictable.  You could do a project on density of objects or environmental testing.

Hey Elyne!  I'm Kassi and this year me and my science partner are doing a project on testing which baseball bat is better - alumimum or wood, and if the batter affects that. But we are getting some help from a pro baseball player, so I hope that helps.

Get a glass big enough to fit an egg in and put water up to halfway. Put loads and loads of salt and the egg will float.

I got to study either rocks or family culture for my science fair project.  I did it once and got an A+.  I was so happy that I almost cried that day.  I hope you do well on that grade. I will cross my fingers for you.

If your project is an experiment project then these are a few ideas that may help. 1. What rusts a nail faster - lemonade, soda, or orange juice. Just to let you know you can choose the liquid(s) that you would like to experiment with 2. Who has better memory- men or women? 3. If you eat a certain amount of food but just different foods with the same amount, will it affect the way or how fast you run.

Hope these ideas helped,

Samantha:)

How to make eggs float would be a good science fair project.

It would help to know what grade you're in.

Also, what topics you're interested in?

Physics, Botany, etc.

I did my project on physics. Magnetism and other forces can be really interesting. At my science fair I was able to bring in my project and show a demonstration. 

In my brother's project, he launched a metal ring using magnetic propulsion and tested the relationship between distance and voltage.

Hope this helps.

A toilet paper tube with a bunch of lights stuck to the outside, it makes a video camera finder. Turn off all the lights and look through the tube around the room, the light glints off lenses.

Hi there !
My name is Rebecca, and what me and my partner are doing is how different articles of clothing help prevent hypothermia :)

It's more of a challenging one, but our science teacher said that it's going to be an interesting one too see :)
Have fun, and good luck !

Science Fair was the hardest project I ever did. My project was not very amazing.

Hi, my name is Brandon. You could make a volcano out of paper mache. Then paint it and put a test tube inside. Then fill volcano with baking soda, then pour a mix of vinegar+red food dye. Then it should fizz up all over the place. I have not tried it but it should work.

You know what would be so cool? If you would watch food rot.

Why not make a fan made out of things good for the earth.

My name is Busra. Ideas for a heating shoes. I think it is a good idea.

One idea is to find a bunch of plants of the same kind and put two in the light & two in the shade. Water one from each group with hairspray and the rest with water. Tell which dies first.
