Not directly on point, but you might want to check out my blog SciBricks for LEGO science ideas.
More on point, back in the 90's LEGO had several Dacta mechanics sets on things like gears, pulleys, levers etc:
I found a couple of these at a thrift store once and they have some simple contraptions to teach kids about the basics of mechanics. A quick look on Bricklink shows that you could pick up these relatively reasonably. Even better, just get the teachers guide, and then get some loose technic beams and gears etc - I'm sure you could get more bang for your buck that way. If it's for this fall you'll have plenty of time to get something put together.
