Volcanoes: Where and Why? Crustal Evolution Education Project. Teacher's Guide [and] Student Investigation.

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 two 45-minute class periods; (8) summary questions (with answers); (9) extension activities; and (10) list of references. In these activities, students find differences in the chemical compounds that make up various rocks, plot a number of volcano sites in and around the Pacific, and relate their observations to plate boundaries and motions. In addition, students tell how volcanoes are different and classify them into certain groups. (Author/JN)
