Thousand-Year Old Mayan Teeth!

Guest speaker (and Ruby's Dad) Professor Alan Goodman visited our classroom yesterday with a mystery:
Imagine you are vacationing in Belize and visit an ancient Mayan ruin. You see a rock slab and decide to raise it up to see what's underneath and you find over 300 teeth!

Whose teeth were they?

How old are the teeth?

How old were the people whose teeth were removed?

How was the health of those people?

Were they men or women, boys or girls? Did they have many cavities?

Were they taken out (shudder) while the people were alive, or (shudder) long after they had died?

Were they a sacrifice to the toothless rain god Itzamna?

We studied the teeth to find the answers to some of these questions and to ask some questions of our own!

Thanks, Alan! What a great experience you shared with us!

Alan greeted us in Mayan!
