Using a dichotomous key, students will identify mammal skulls. They will learn tooth types, how the teeth provide clues about whether the animal is a carnivore or an herbivore, and how teeth can help people identify what kind of animal they came from. Students will generate a hypothesis (prediction) about the animal's preferred foods, learning how structure relates to function.
