Before Watching

  1. Ask students to find Madagascar on a world map. How might the fact that Madagascar is an island affect its biodiversity? What kinds of animals might live there?

  2. Discuss with students the concept of an energy pyramid. Be sure to emphasize the direction of energy transfer in the pyramid from prey to predator.

  3. As students watch, have them take notes on predator and prey relationships on Madagascar. Organize the class into three groups to take notes on 1) land animals and plants, 2) animals that live in the water, and 3) animals that primarily live in the sky. Have students create a chart with columns labeled "animal name," "eats," and "is eaten by." Students can use their notes to complete the "Home Sweet Home" activity.

After Watching

  1. Ask students to describe the role played (niche occupied) by the lemur in its community, or that played by the crocodile. How are these roles alike? How are they different? What might happen if the lemurs moved into the caves and the crocodiles moved into the forest?
