Summary:This report contains instructions and patterns for preparing a set of four, 3-D paper models that schematically illustrate the development of island coral. The first model is of a shield volcano that extends above sea level, making a volcanic island. The second is of the original shield volcano and volcanic island that have developed a fringing reef of coral growing at sea level. The third model is of a lagoon and a barrier reef after a rise in sea level. The coral reef has grown, producing a lagoon between the volcanic island and the reef, (scientists call this a barrier reef). The fourth model is of an atoll. Most of the original shield volcano has disappeared because of the continual rise in sea level, as the growing coral kept pace with the rising water. These models are intended to help students and others to visualize the growth of coral on islands and to learn some of the terminology used by earth scientists to describe coral reefs. By constructing and examining these model landforms, students will achieve a greater appreciation of the relations between volcanic islands, the growth of coral reefs, and atolls.
