When I was in Junior high we did this experiment with an egg in vinegar. You put the egg in a cup of vinegar and cover it up with plastic wrap or foil. Then in about a week the shell will come off and you will end up with just a clear egg. I will come out looking like the picture in the first link below. It looks even cooler when you add food coloring.
I also did another experiment. You take some steel wool (the stuff you scrub dishes with). Then you mix bleach and vinegar. Next soak the steel wool in the bleach and vinegar for a couple of hours until it rust. After that you take it out and dry it off. Then burn the steel wool in a spoon. It will become magnetic and look like iron filings. Test it out by putting a magnet on it. (I don't have a source it if just from memory).
The second site is just a site that I found.

What kinds of things are you studying right now? Plants? Electricity? Motion? Selecting something that relates to what you have been working with can make the experiment more meaningful and may make it easier to find the supporting material that you need.
How much time do you have to complete the assignment? Is this something to be done by the end of the year? If so, sprouting plants under different lighting/soil/moisture/whatever conditions may work. If it needs to be done by tomorrow, that obviously won't do.
1. Create your hypothesis: "when I do X, I predict that Y will happen"
2. Set up an environment where you can change X, and _only_ X. You might change X in a number of ways or in different amounts (if X is the temperature at which you are sprouting beans, you might try four different temperatures).
3. Remember to include a control, where there is no change to X
4. Record your results
5. Was your hypothesis valid or not?
6. Present your results neatly. Include why you chose your hypothesis, what your experimental setup was, how you monitored your experiment, your observations, and your conclusions. Use photos or diagrams to document your work. Present results in a way that is easy to understand. A table of bean sprout heights may represent your data accurately, but a graph would probably convey the information more easily.
Don't fudge your data!!! There is no such thing as a failed experiment.

what do you think of this?!? i don't know which 'science' you are looing for, this is physics:
lift.
it can go up and down.
it is quite simple, my bro did the wires, he understands something in electronics... maybe you might ask someone to help you with this?!?
i did this as a technology project, and i got full marks. the assesment however was based on my verbal presentation of the project, not the project itself - i admit it was quite ugly to look at, i used hideous colours to paint it as i did it in the last minute.
hope that helped a little, and good luck!!!

You don't say what age level or grade???? use a magnet, typing paper and iron filings to show the flux pattern of the magnet. this is a old example but always fun to do

A good one that won my nephew 1st place was Recycling.
Recycle Paper..how it works, etc. Try to do some research on the steps.

MENTOS AND DIET COKE... WATCH IT BLOW...
yeah I love the project so try it... It's funny
