1. The effect of different liquids on teeth
2. The effects of salt and other contaminants on rate of rusting
3. The effect of temperature on the growth rate of crystals
For #1, I was thinking about using either real teeth or egg skins to represent the teeth. Then I'd use three liquids (probably milk, orange juice, and soda) and see which dissolves the tooth or egg the most in a given amount of time.
For #2, I was thinking about using three different contaminants to see which would make an iron nail rust fastest. Any ideas for the contaminants?
For #3, I'd grow crystals somehow (?) and see if growing them in the cold differs from growing them in warmth.
Which one do you think is best? How could I go about doing these experiments? Any suggestions for different experiments?
