We wanted to see the effects that different things have on our teeth. We used hard-boiled eggs to represent our teeth, because we observed that the eggs are white and have a hard surface, just like our teeth. Then we each got a cup and poured a liquid into it; either water, sugar water, soda, or iced tea. The eggs are going to sit in those liquids overnight.
Each of us made a hypothesis. Some of us thought the egg would crack. Others thought it would disappear! And a couple thought the egg would change colors.
We can't wait to see the results!
