Before Watching
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?
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.
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
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?
