Presented is an activity in which students construct a model of plate divergence with two sheets of paper to show the separation of two continental plates in a system of spreading ridges and faults. Diagrams and procedures are described. (CW)

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 summer program for teachers in the Hawaii Volcanoes National Park in which teachers share in hands-on activities that demonstrate volcanic processes including volcanic hazards, plate tectonics, and earthquakes. (DDR)

Pans of popcorn are popped to varying degrees in order to compare them to the earth's surface with volcanic pressure building up in this demonstration. Volcanic activity is also related to bodily functions to help students make connections. For example, the release of gas through burping after drinking soda pop is related to the release of…

Designed to serve as a complement to the Unesco Technical Papers in Marine Science, this report concentrates on theoretical and practical problems of geological mapping of the sea floor. An introduction is given to geological mapping procedures at continental margins as well as some practical recommendations taking as an example the African region…

Describes an exercise which provides a small data set consisting of the localities where various genera of a fictitious group of fossil "Archaeomorphs" have been found on various continental blocks. The activity can be used to develop hypotheses regarding plate tectonic processes and the present arrangement of fossil localities. (TW)

Reports on an investigation of 31 introductory geology textbooks indicating that the concept of contact between bodies of rock is only rarely discussed. Data collected pertaining to 15 related terms demonstrated that many are either omitted or inadequately covered. (TW)

Suggests that there is a close relationship between deformation in the western United States and the large-scale motions of tectonic plates. Introduces very-long-baseline interferometry (VLBI) as one of the space-geodetic techniques, vector addition of the VLBI data and geological data, and a new geodetic network. (YP)

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)

This CD-ROM uses catastrophic events to teach the fundamentals of the earth's dynamism. Topics discussed include earthquakes, volcanoes, hurricanes, plate tectonics, and many subjects that have to do with energy transfer. It contains 63 interactive, inquiry-based activities that closely simulate real life scientific practice. Students work with…

This activity introduces students to the basic concept of seafloor spreading, the processes involved in creating new seafloor at a mid- ocean ridge, the Galapagos Spreading Center system, and the different types of plate motion associated with ridge segments and transform faults. The activity provides learning objectives, a list of needed…

Reviews The Best of BAESI: Earth Science Activities & Recommended Resources from the Bay Area Earth Science Institute. The Best of BAESI is divided into two parts. Part I contains 19 classroom activities on topographic maps, rocks and minerals, earthquakes, volcanoes, and plate tectonics. Part II describes resources and identifies government…

Reviews a model used in the teaching of plate tectonics which includes processes and concepts related to: terranes and the amalgamation of terranes, relative plate motion and oblique subduction, the effects of continent-continent collision, changes in plate motion, plate configuration, and the type of plate boundary. Diagrams are included.…

Discusses the use of a strip log as a diagrammatic representation of the information available in a sequence of sedimentary rocks. Describes the design of the strip log (both symbolically and by visual/spatial patterns) and some of the possible interpretations that can be made using them. (TW)

Several studies of the validity of the intensive time-series design have revealed a post-intervention increase in the level of achievement data (the "momentum effect"). Reports on the development and use of a technique to study the effect as it is observed in several data sets on the learning of plate tectonics. (Author/JN)
