Answer 6

Teachers love projects with electricity and magnetism.

A really simply and cheap project that usually surprises people is a Leyden Jar. It is basically a plastic jar or Tupperware that is lined on the inside and outside with aluminum foil. The foil on the outside does not touch the foil on the inside. When you hold the inside foil up to a TV screen, it will store an imbalance of charge. Then try to connect the two layers of foil, and a spark will jump. (You can also shock people with it). It is much simpler than  my rudimentary explanation makes it seem; check out this link:

There are also other options. You can build a simple motor or a solar cell, and you can do many things with fire. Try out this website:
