Computer programming. Older versions of basic are freeware. Get a visitior with some command of the language to come in and talk about programming basics.

When I was in 7th grade I had a few science projects. One was making a space station out of household objects...nothing could be purchased. Also making a poster of the periodic table or making the solar system were fun too.
Also we learned about solar energy with a shoe box, aluminum foil, coat hangers and hot dogs. We put aluminum foil in the bottom of the shoe box, ran coat hanges through then ends with a hot dog on them. Unfortunately is has to be sunny outside.
