Describes a three-week activity unit on earthquakes that addresses the National Science Education Standards. Includes mantle convection, crust, plate tectonics, and faults concepts. (YDS)

Discussed are several phenomena associated with earthquakes. Included are seismic waves, plate movement, and earthquake measurement. Diagrams of different plate boundary types are included. An activity for teaching these events to elementary school children is provided. (CW)

Describes a computer simulation called "Supercontinent Aggregation and Dispersal" designed to model the interplay between the movement of the continents and the flow patterns of rock in the mantle. Discusses the strengths and weaknesses of the program in relation to the effects of continents on the mantle. (CW)

Describes a laboratory exercise testing the Vine-Matthews-Morley hypothesis of plate tectonics. Includes 14 questions with explanations using graphs and charts. Provides a historical account of the current plate tectonic and magnetic anomaly theory. (MVL)

Develops an exercise in which students use magnetic-profile data gathered in the South Pacific to test the Vine-Matthews-Morley hypothesis. Uses the Eltanin 19N and 20N profiles. Relates the exercise to 20 current geology texts. (MVL)

This teacher's guide and student text detail the causes and effects of earthquakes and tsunamis. In the teacher's guidebook, suggested activities for each section of the text book's chapters as well as answers to the chapter test problems are presented. Worksheet masters are also provided. Chapters in both books are: (1) "Outside and Inside…

Describes a computer program written in Microsoft BASIC for use on personal computers to calculate travel times of refracted waves in layered structures with arbitrary dipping interfaces. Exercises for student use are given to illustrate some of the basic properties of reversed refraction travel time graphs. (TW)

The student textbook is designed for grades 5-8 and explores various earth science topics. A cartoon character named Tommy Tsumi explores earth facts and concepts throughout the text. Activities, materials, and learning objectives for each unit in the textbook are presented in the teacher's guide. Units in both books include: (1) "The Outside…

Provides background information on the layers of the earth, the relationship between changes on the surface of the earth and its insides, and plate tectonics. Teaching activities are included, with some containing reproducible worksheets and handouts to accompany them. (TW)

This student text is designed for grades 2-4 and explores various earth science topics. A cartoon character named Tommy Tsumi explains earth facts and concepts throughout the text. Activities, materials, and learning objectives for each unit in the textbook are provided in the teacher's guide. Units in both include: (1) "What Does Our Earth…

The topics of earthquakes and volcanoes are important to children but are often missing from elementary science textbooks. This document is a part of "The Natural Disaster Series" and is an attempt to supplement elementary science programs with lessons and student activities. Reasoning skills are also stressed throughout the document.…
