The main objective of this lesson is to demonstrate the differences in teeth
structure and how it determines what a specific animal eats. This will be
accomplished by constructing a raccoon puppet.
pictures of various animals (focusing on their mouth)
paper bags (4" X 8")
red modeling clay
black and brown crayons
1. Display pictures of various animals, discussing their teeth structure.
2. Lay the paper bag flat with the flap facing you.
3. Draw a raccoon face above the flap. Allow the students to get creative
with their puppets faces.
4. Turn the bag over to, allow some space at the top, then draw the raccoon's
5. Lift up the flap and glue two strips of clay (one on top and one on bottom)
to the bag. These should represent the gums of the raccoon.
6. Place individual corn kernels in the clay to represent the different kinds
of teeth. Instruct the students to position the kernels so that the front
teeth are sharp and the back teeth are smooth and round.
7. Allow the students to demonstrate the functioning of their puppets to one
At the completion of these activities the students will be able to answer
the following questions:
1. What do omnivores eat?
2. What do carnivores eat?
3. What do herbivores eat?
4. How do the structure of an animals determine what they eat?
5. Describe the different shapes of animal teeth.
6. Can the learner apply this information to the identification of dinosaurs?
At the conclusion of this activity the students will understand the
differences in teeth shapes and how this dictates the diet of an animal.
