Before Watching
-
Find out what students know about coral and coral reefs. Locate
the Great Barrier Reef on a world map. Ask the students if they
can identify other locations in the world where coral reefs can
be found. As they watch the program, have the students take note
of the special geologic and climatic conditions that make it
possible for a coral reef to exist.
-
One of the unifying themes in this program is the concept of
mutualism, in which two or more species depend on each other to
survive in a particular environment. Several examples of
mutualistic relationships are presented in this program.
Encourage the students to look for these examples as they watch
and to pay attention to the ways in which different plants and
animals survive by depending on each other.
After Watching
-
Review students' notes about the conditions necessary to allow a
coral reef to exist. Which variables seem most important?
