Chemistry science fair projects have changed over the years; they've gotten a lot glitzier and much more technically involved. While this is has made it somewhat easier for parents, the modern trend in science fair projects tends to be to buy a science fair kit off the internet rather than make things yourself. We're going to cover old school style chemistry science fair projects that will set you apart. First, there's something to be said for the "do it yourself" method of doing science fair projects. A lot of really good scientific learning can be done with this, and the hands-on experience is excellent for associating science with the real world, particularly with chemistry. Some good hands-on chemistry science experiments: Salinity and Freezing temperatures Take a liter of water, carefully measure it out into ten glasses of 100 cc each, and add salt to each of the four glasses. Put no salt in the first glass, 10 grabs (about half a teaspoon) into sec...
