My first unit in science is on rocks, so I'm ready with a few fun and purposeful activities for my students. Edible rocks! Check out the pdf on google docs. I did not create it, don't know where I found it, but the author's name is on the file (Emily Shea). Update: I found the author and the link now takes you to her original file:)
And special kudos to anyone who can tell me what that guy in the pic is, what movie he is from, and what he eats!
