1. Dissect on owl pellet using the bones to determine the prey using a dichotomous key.
2. Discuss predator-prey relations.
3. Discuss predator and prey adaptations using animal skulls.
Objectives
1. Students will define biodiversity and apply knowledge of food chains, food webs, energy pyramids and niches in ecosystems.
2. Students will dissect an owl pellet and utilize a dichotomous key.
3. Students will identify the three types of teeth and determine an animal's role in an ecosystem.
4. Students will engage in a discussion on predator and prey adaptations.
5. Students will engage in a discussion on population control and predator-prey dynamics.
