I have tonight (for research and planning) and tomorrow left for my assignment (yes I procrastinated).

I need something simple(so I coud do it in a day) but still interesting. Something different.

You could investigate the "brazil nut problem." If you shake a can of mixed nuts, the largest (and presumably most dense) substance, the brazil nuts, wind up at the top. If you take a jar of rice and put in a ball bearing, and shake it up, the ball bearing winds up at the top. But you learned in school that the more dense substance should go to the bottom. You could do a little reading on this topic, and then you could take a jar of rice and put in various objects (rocks, washers, piece of wood, etc.) or use macaroni noodles or whatever to see whether the size, shape, or weight of the objects matters. Be sure to relate what you observe to what you have learned from your reading. Enjoy.

And next time, get on the stick a little sooner, k?

Go to a hobbie store and get two bottles of Copper Sulfate from a kids chemistry kit.

Go to radio shack and get some NICKLE hook up wire, 20 or 22 guage, solid or stranded. Get a 9 volt battery and a battery cape for the 9volt battery.

Mix the ONE bottle Copper Sulfate into a half a glass of water.

Wire up your NICKEL hook up wire to the battery cap and battey. Strip a long section of wire. Put the wire into opposite ends of the glass and wait a minute or two

Remove the wire, that NICKEL wire should now be plated with copper.

Electrons flowing through the solution drag the copper molecules and bind them to the nickel.

Electroplating.

It's how they make Gold Plated junk jewerly.

It's how they make Metal MASTERS for pressing DVDs, CDs and phonorecords.

Once you did this yourself, take the rest to class and do it there.

make paper airplanes of different shapes and sizes and see which ones fly the best...

You will need to design some sort of "launcher" (perhaps a rubber band on a platform) to test them all about the same...

You should make a chart and some graphs to display your data collected...

You may want to weigh each one, if different sizes or you may want to make them all out of the same size piece of paper (say a piece of typing paper)...

Look around the Internet for designs.. or go to the library to find some books on paper airplanes.
