The theory of plate tectonics represents a revolutionary breakthrough in the earth sciences, providing a coherent model of how the outer surface of the Earth moves and changes. In these activities, students conduct simulated research at key geological sites around the world. They visit Hawaii, California, Iceland, Japan and Nepal, and their investigations range from the bottom of the ocean to the top of Mount Everest. Classroom models of erupting volcanoes, strike-slip faults, rock layers, and sea-floor spreading help reveal the dynamic nature of the Earth's crust. Students record observations, calculations, and conclusions in a geological field notebook. Plate tectonics is a challenging subject that many middle school teachers are required to teach. This new GEMS guide provides clear, step-by-step presentation instructions, concise and accessible background information, built-in assessments, resources, student reading and literature suggestions, and helpful suggestions from teachers who tested the activities in classrooms nationwide. These activities use readily available materials and no special science knowledge or background is required to present them. Grades 6-8 8 activities 220 pages $24.00 ISBN 0-924886-60-9 Available late January 2002 |
