Hi,

This website and this website has links to other websites and project ideas. I did not look through all of them so I am not sure how budget friendly they are or if they are age appropriate as I did not know how old your child is. But there is a bunch so I hope you can find something to work.

updated - JUST REALIZED MY POST DOESN'T INVOLVE ALTERNATIVE ENERGY... sorry... maybe it will help someone else though...

Once we did a project about popcorn. You would need just regular popcorn kernels (not microwave popcorn) and baggies. It was an experiment to see if popcorn popped better if cold (refrigerated) vs room temp. We might have also put some in the freezer, I can't recall. If you google "science fair popcorn refrigerator" you should be able to get the information to do the project.

Thought you might already have these items at the house. Hope that helps.

I'm going to move this over to the CB and give it a bump. I'm hoping that you'll get some more ideas from members who post there. Good luck to your DS!

You didn't say how old he is, but if he's young, the old lemon-battery test might be good, accompanied of course by some research on the efficiency and output potential of voltaic batteries in general.

If he's older, I'd suggest making biodiesel out of some kind of unusual plant oil. You can use a lot of junkyard-sourced equipment to do it; it's a little like building a still.
