Science Buddies: "Ask an Expert"

Hi alexaceves,
In order to discover the similarities between eggshells and teeth, I recommend that you do some selective searching on the internet, using google, or science encyclopedias. You can also research the compositions of the eggshells and teeth separately, and then compare their compositions in order to discover their similarities. I also found a site which directly answers your question:
