Have students work in small groups and use mirrors to observe their teeth and mouths so they can sketch and describe the shape of their teeth. Read aloud the worksheet directions for Part 2: Observations. Have students collect more information to test their predictions.ĭivide students into small groups. Allow students time to make their predictions and complete Part 1.ģ. Read aloud the worksheet directions for Part 1: Prediction. They will test their predictions by collecting more information. Tell students that they are now going to make predictions about how their teeth and jaws compare to those of a lion. Humans are omnivores so their mouths are designed to eat both meat and plants.
