Help - electric circuit project for 6th grader?

Question

I know someone who has a school project where they have to build/invent something interesting or useful that uses an electric circuit.

Do you have any ideas of a good project for him.

If so, please tell me the project idea and how to construct it.

Try and keep it relatively simple (for a 12 yr old) and not too expensive.

Answer 1

magnets are a fun, safe way to play with electricity.  batteries can be expensive, but if you have some old tools lying around you could try this:

wrap a piece of wire, a thicker piece of wire is better, around an Allen wrench.  the L shaped tool with a hexagram shape.  wrap it very tightly and hook either end to battey.   now you have a safe electro-magnet, and you can do a lot of research online to make snazzy charts explaining how it works!  just a suggestion, electricity is limitless, have fun!
