2. Crafting The Very Hungry Caterpillar: To bring our caterpillar to life, trace a tin can on red construction paper to form the mouth of the caterpillar. Cut out a large circle for the face or head, then fashion two large yellow ovals and two slightly smaller green ovals for the eyes. Glue these pieces together and attach them to the head. Don't forget to cut out and add the green antennae! Finally, secure the caterpillar head to the tin can using masking tape.
