This curriculum guide is designed for use with the Charles E. Merrill textbook "Focus on Earth Science" and with the laboratory manual, teaching guide, and student review and reinforcement guide which accompany the textbook. Suggested time allotment, major concepts, instructional objectives, assessment items, available materials (such as films, charts, models, and transparencies), and suggested activities are provided for chapters 12 to 25. These chapters focus on: erosion, mass movement, and wind; water systems; glaciers; earthquakes; plate tectonics; landforms; geological dating; geologic time; renewable and nonrenewable resources; energy resources; universe, galaxies, and stars; solar system; and space voyage and exploration. Enabling objectives for essential learner outcomes, basic objectives which each teacher must teach but not requiring 100 percent student mastery, assessments and activities requiring minimal reading skills, and assessments and activities for accelerated students are noted when applicable. Supporting materials provided in an appendix include activities on rockets, measurements, and tides; tips for maintaining saltwater aquariums; and a list of animals found in bottom communities of the upper Texas coast.
