This article proposes an evidence-based and engaging approach to teaching the mechanisms driving the movement of tectonic plates that should lead high school students towards the prevalent theories used in peer-reviewed science journals and taught in universities. The methods presented replace the inaccurate and outdated focus on mantle convection…

Current high school Earth Science curricula and textbooks organize scientific content into isolated "units" of knowledge. Within this structure, content is taught, but in the absence of the context of fundamental understandings or the process of how the science was actually done to reach the conclusions. These are two key facets of scientific…

Described are concepts involved with the formation and actions of the Mid-Ocean Ridge. Sea-floor spreading, the magma supply model, discontinuities, off-axis structures, overlaps and deviation, and aquatic life are discussed. (CW)

Points out that large earthquakes can take place not only on faults that cut the earth's surface but also on blind faults under folded terrain. Describes four examples of fold earthquakes. Discusses the fold earthquakes using several diagrams and pictures. (YP)

This teacher guide presents a unit on plate tectonics and introduces hands-on activities for students in grades 6-8. In each unit, students act as real scientists and gather evidence by using science process skills such as observing, graphing, analyzing data, designing and making models, visualizing, communicating, theorizing, and drawing…

Investigates the nature of catastrophic volcanism and the rifting process. Describes two kinds of evidence: quantitative descriptions of rock melting and a wide range of observations. Discusses examples of continent growth in the North Atlantic, India and the Seychelles islands, and the South Atlantic. (YP)

This activity is designed to teach how tectonic plates move, what some consequences of this motion are, and how magnetic anomalies document the motion at spreading centers do. The activity provides learning objectives, a list of needed materials, key vocabulary words, background information, day-to-day procedures, internet connections, career…

Discussed are two techniques that can be used to directly test the theory that the plates which make up the crust of the earth are still moving. Described are the use of satellite laser ranging and very long baseline interferometry. Samples of data and their analysis are provided. (CW)

Examined is the science of catastrophism and its role in planetary and earth science. The effects of impacts on earth with extraterrestrial origins are discussed. Perspectives on the age and dynamics of the earth's crust are presented. (CW)

Presents a reproducible page for students dealing with the following topics: plate tectonics, magma, crust, and earthquakes. Provides a plate tectonics activity that uses cardboard and clay. (PR)

This CD-ROM contains 17 computer-generated teaching tools, 16 interactive HyperCard "stacks", and a printable model. The 17 tools are separated into the following categories: (1) Geologic Processes; (2) Fossilization; (3) Earthquakes and Faulting; and (4) Map Projections and Globes. A navigation stack, "Earth Science," is provided as a launching…

Discussed are some of the reasons for earthquakes which occur in stable crust away from familiar zones at the ends of tectonic plates. Crust stability and the reactivation of old faults are described using examples from India and Australia. (CW)

Presents an activity that uses the study of earthquakes to provide a rich educational experience to reinforce and expand students' knowledge of the structure of the Earth, provide an application of physics concepts such as force and energy, and present these topics integrated with a unit on mathematics. (JRH)

Provides easy to teach and understand laboratory exercises for three fundamental concepts (plate movement, rock mechanics, and geologic time) that are often left out of the geology and Earth science curriculum. (ZWH)

Describes three activities to help students understand plate tectonics. (PR)
