Make a terrarium, it's like an independent Little Eco system. Get a jar with a lid. First layer pebbles, sand, and then topsoil. Go to a Green house and get a few small plants, tropical plants usually do well in this enviorment. Fill a pop bottle cap up with water and place inside. Replace the lid, and put in a sunny spot. I made one when I was is 6th grade, and it lasted for years. I only needed to open it a few times to add more water, but with the evaporation, and moisture the plants survived.

Talk about why some chili peppers get hotter than others given by the climate they grow in. Then make some salsas for people to taste and rate and guess where they're from on a map. All this can be found with some internet research.
Otherwise, diagram how a toaster works, the heating mechanism, the timer, the mechanical mechanims. Then make toast. The best science projects involve food!

This was kind of gross, but very interesting...
In seperate petree dishes, place a couple of drops of water from the following locations and see what grows over the course of time:
* Sterile distilled water (from a pharmacist) - this is your control dish
* Distilled water (from regular grocery store)
* Brand name bottled water
* Regular tap water from your home kitchen sink
* Regular tap water from a drinking fountain in your school
Having a microscope to look at the results is great but not needed. The time I saw this done, you could clearly see what grew in those dishes with the naked eye.
