In this activity, learners make edible T. rex teeth (with adult assistance). The treat is a white and dark chocolate covered banana on a stick. The white chocolate represents the tooth and the dark chocolate represents the strong part of the T. rex tooth. While learners wait for each chocolate layer to cool, they must count the Cretaceous Period by fives all the way to 65 Cretaceous million years ago. This activity is featured on page 41 of the "Dinosphere" unit of study for K-2 learners.
