depending on how much time you have...It may sound gross, but call a local oral surgeon and ask for some extracted teeth. Ask them to sterilize them. Ask for 6-8 teeth.
Collect various reactants, like lemon juice, peroxide, water, soda, bleach, glycerin, etc.
set-up a separate little jar (empty baby food jars work best) for each medium and place a tooth in each jar.
Create a question and a hypothesis and watch a wait. In a week to 2 weeks, check the results and document.
You would be surprised at what happens to the teeth. It's fun too, but I work in the dental field.
