Teeth vs. Soda

Title: Teeth vs. Soda Pop

Problem: What is the effect of the different types of soda on how fast they rot your teeth?

Hypothesis: We think that pepsi will rot your teeth faster then the others.

Materials: 2 raw eggs, 2 hard-boiled eggs, pepsi, 7-up, Brisk, Crush

Procedure:

1) We took one hard-boiled egg then put it in the Pepsi.

2) We put the other hard-boiled egg into the 7-up.

3) We tool one raw egg and put it in the Brisk.

4)Then we put the other one in the Crush.

5) Each day we checked what happens to the egg and record it on the graphs.

6) We left them in there for 6 days.

Conclusion: Our conclusion is that our hypothesis was right because pepsi made the egg rot more than the others in 6 days. The shell was so dark and part of the shell cracked because the shell got softer.
