Students identify locations of coral reefs, both in the water and around the globe, identify relative depth of corals in the ocean by observing behavior of cold and warm saltwater, and create models of coral reefs.

Students are told that after they discuss and examine of rainforest caterpillars, they are going to create their own rainforest caterpillar based on the information they have studied. They are given the habitat scenarios on 3x5 cards.
