HYPOTHESIS
My hypothesis was: If I put 5 different soda
pops in a separate cup from each other
with an egg then Coke will be worse for
your teeth because it has more sugar and
more sodium.
MATERIALS
Mountain Dew
Dr. Pepper
Sprite
Coke
Fanta
Water
6 eggs
6 cups
PROCEDURE: STEPS
1. Gather materials.
2. Put eggs in cups.
3. Pour 250 milliliters of different soda in
each cup.
4. Put water in egg with cup.
5. Leave in refrigerator for 1 week.
6. Check once a day.
7. Record results.
VARIABLES
Constants: Soda and water
Controlled variables: Comparing sodas
Independent (manipulated) variable: Water
Dependent (measured) variable: How
much the egg breaks or decays.

CONCLUSION
I concluded that Fanta stains your teeth
more and that colas like Coke and Dr.
Pepper rough up your teeth. So my
hypothesis was correct and wrong.
