Well, it depends how old you are. If you wanna go really easy, you could demonstrate Bernoulli's principle with a few sheets of paper and a fan

Two things are infinite: the universe and human stupidity, and I'm not too sure about the former.

Join my army[[!

Make Sirius System model using aluminium foils and spray paints. Don't forget the Jump Gates, Trade Lanes, and battleships.

try to explian the big bang theory, if that doesn't work explain what nuclear fusion really is about

hm . . .
there were people doing soils and stuff
its like this;
get different sorts of soil;clay, sand, and other stuff, and do some researching, see which goes on top, which on the bottom which is sandwiched.. and so on.. but u'll need more than 3 layers to impress the judges..
and there were some physics things..
there was this tunnel kinda thing, like a roller coaster only its a tunnel, and gaps, in them, and you put a ball thing at the top and do all the maths and physics and the ball flies into the air and into the next section, ususally faster when you do it with trial and error..
then there's the typical volcano..
or you can electroplate everyone's blades with sodium but u'll need mercury..
watched jimmy neutron?

presently, my world is upside down, so if u do not mind, u'll have to tok to my a$$

time to put an end the floating blue bastards[![!

Well it is project for 8th grade.I do not realy care what kind because I am doing this because my teacher made whole class do it so something easy and simple.

A+ material. plus, compiling research has never been so fun!

You can do a presentation on fuel cells. Or mebbe do fireworks. I did fireworks for grade 12 science project. Oh wait...gr 8 eh? nevermind.

Hm.....

ya, do my river soil one. it'll get you good marks if you do it neat.

You could make a Potatoe powered clock

those are classic. lemon or lime powered stuff would also work, yes?

Demonstrate how you can cook your hotdog by connecting both ends of the hotdog with electrical wires and plugging it in. Then get a cucumber pickle (whole, not sliced), and do the same with the hotdog wiring, but only this time, the pickle does not cook, because of the iron in it acting as conductor.

Conclusion: non-conductive items (hotdog) generates resistance and then heat, while conductive items (pickle) don't.

I stole that from CSI

If any of you have seen Mallrats, you will know what you can try to do with a Certain piece of equipment and some chicken wire

Make a small amount of Nitrogen Triiodide (be very careful or get a teacher to help make it) now on Science Fair day give it a good slap with a metre ruler. Its a touch explosive, not terribly strong but nice bang and purple iodine vapours create a great show

Hey Fear Factor I like yours about hotdog and pickle I might do it if there arent any better ones.
