Hi,

I need an idea for a science fair project really quickly. Perhaps something associated with agriculture or electricity or maybe alternate fuels. Ideas in any field would be really appreciated. I can spend around 100 dollars. Thanks in advance for helping.

Send me the 100 dollars and I'll show you how to get methane using a cattle prod. Agriculture, electricity and alternative fuels all in one.

send me a hundred bucks and I'll give you 3 copper engravings of president Lincoln... trust me, their collectables, and the value will go up over time.

Ok after factoring in your price range I think an experiment in alternative fuels is a good path. I would construct the experiment as a comparison and then change the varibles (such as temperature or amount of fuel or something) and see which preforms better. So $20 of gas, $10 solar cells around $50-70 for a small cheap diesel engine (I think you can get them that cheap, not sure) and some third fuel.

 

That's just one basic idea, hope that can help. If not I hope it didn't completly waste neuronal space.
