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?
