Subject: How do I determine the effect of acidic liquids on teeth, chicken bones, an

eggshells?  I am doing a science project exposing my baby teeth, chicken 
bones and eggshells to acidic liquids of varying PH: lemon juice, vinegar, 
cola, and water (control).  How do I determine if the liquid has drawn 
calcium out of the teeth, chicken and eggshells.  I expect the bones and 
shells will get soft, but how long would it take for teeth to soften?  
Also, is there some way to test for the amount of calcium in the liquid?  
I think my hypothesis might be that stronger acids will draw calcium out 
of bones more quickly than weaker acids, but how do I measure this?  Is it 
possible or just to complicated for a 5th grade project?  Please answer 
quickly.   Thank you,
