The Grade 3/4 students compared how cookies and rocks are alike. They dissected rocks (cookies) by carefully removing the minerals (colored chocolate chips) from each rock (cookie). They used special instruments (toothpicks and popsicle sticks) to carefully remove the minerals (chocolate chips) so that they didn't break into small pieces.
"This is so much fun. I see how careful a mineralogist would have to be."
"This is really hard. It takes a lot of concentration."
"I might want to be a mineralogist because this was so much fun."
