Crustal Evolution Education Project (CEEP) modules were designed to: (1) provide students with the methods and results of continuing investigations into the composition, history, and processes of the earth's crust and the application of this knowledge to man's activities and (2) to be used by teachers with little or no previous background in the modern theories of sea-floor spreading, continental drift, and plate tectonics. Each module consists of two booklets: a teacher's guide and student investigation. The teacher's guide contains all of the information present in the student investigation booklet as well as: (1) a general introduction; (2) prerequisite student background; (3) objectives; (4) list of required materials; (5) background information; (6) suggested approach; (7) procedure, recommending three 45-minute class periods; (8) summary questions (with answers); (9) extension activities; and (10) list of references. Using volcanic areas ("hot spots") as the focal point, students record patterns existing in familiar earth materials, describe the force necessary to produce these patterns and force produced in areas located over hot spots, identify crustal plates moving rapidly and those moving relatively slowly, describe surface features in a hot spot area, and describe what changes take place as a hot spot continues to develop.
