Science!!!???

Mari: Science!!!???
My question for my science fair is: How do drinks effect teeth? I will be using eggs as teeth since they are both made up of calciuum. The sodas (Coke and and Fanta) will be poured into to transparent cups and eggs will be placed in the cups. This experiment will take 24 hours.
What will be my INDEPENDENT VARIABLE?
DEPENDENT VARIABLE?
&
CONTROLLED VARIABLE?
PLEASE HELP ME AS SOON AS POSSIBLE!!!
Thanx!

Eggs as teeth? Perhaps we should use coal as diamonds, since they are both made of carbon?

Anyway, the independent variable is the type of soda you use and the dependent variable will be the the amount of “tooth” decay you observe. This could be the force required to crush the egg.

The control would be an egg left in the open, i.e., not exposed to any liquid at all. You might want to do a “water” control test also where you put the egg in plain water as opposed to soda.

Yeee!!!!??!!!!
