I need a middle school science fair topic.?

Question

I know this isnt the greatest way to find help for a topic, but I'm desperate. I've been looking through various sites, and what seems to interest me is electricity, magnetism, and things along those lines. But I can't seem to find a good enough, specific topic. It needs to be a 'Does..........affect..........' or something like that. So if you have a REALLY good site, or a specific topic that you think can help me out that'd be great. I can usually find good topics but right now i seem to be having a mental block. I really want to do well, but I'm gonna need some help :(

Answer 1

Make a magic act using an electric magnet.

Get a bunch of objects and insert in them a piece of steel or iron, be sure to put it in a place where they will remain upright in midair.
Get information on how to make an electric magnet and control it.
Make the objects "Float" magically in the air when the electric magnet is turned on.
Explain how magnetism makes objects with iron or steel in them float. Use pictures of the magicians Siegfried and Roy - they used electromagnets in their magic act to help them "Fly".
Have fun.
Another idea is to collect a bunch of cheap electronics at a thrift store and demonstrate how electromagnetic waves affect electronic equipment by disturbing their magnetic field.
