We developed and implemented the Galapagos Volcanology Field Camp, a 3 week, 3 credit hour course for upper-level university students with a major course of study in geology. The course is offered by the South Dakota School of Mines and Technology, is open to any student, and is usually populated by students from many universities across the U.S.…

How could a rock formed by volcanic activity get to this shoreline, surrounded by sedimentary rocks? That was the question a group of third-grade students asked--and answered--during an inquiry-based summer camp. Over a two week timeframe, the students practiced basic inquiry skills such as observing; measuring; describing and drawing; sharing…

Imagine recreating a tsunami's force in a bathtub or exploring the potential of geothermal energy by using steam from a kettle to illuminate a light bulb. These types of activities and more are offered in Matthew Levy and Mario Salvadori's collection of experiments and demonstrations in Earthquakes, Volcanoes and Tsunamis. More than 30 easy and…

Within this huge national park (over two million acres spread across Wyoming, Montana, and Idaho) are steaming geysers, hot springs, bubbling mudpots, and fumaroles, or steam vents. Drives on the main roads of Yellowstone take tourists through the major hot attractions, which also include Norris Geyser Basin, Upper and Lower Geyser Basin, West…

Presents a procedure for calculating the compass direction and velocity of present plate motions at any geographical point of interest. Includes a table of the relative and geographic motion of the 11 largest plates and a flow chart for determining their present motion. Also offers suggestions for classroom instruction. (ML)

Discussed is the earth's gravity and its geological significance. Variations of gravity around the earth can be produced by a great variety of possible distributions of density within the earth. Topics discussed include isostasy, local structures, geological exploration, change of gravity in time, and gravity on the moon and planets. (DS)

Reviews seismological studies that provide evidence of the existence of continental roots beneath the continents. Suggests, that through the collisions of plate tectonics, continents stabilized part of the mobile mantle rock beneath them to form deep roots. (ML)

Provides samples of photographs from the book "The Making of a Continent." Photographs, representing a geological feature on the earth's surface, are accompanied by diagrams illustrating how the features were formed. (JN)

Suggests that geographers can serve their communities as Boy Scout merit badge counselors. Identifies several merit badge projects that are closely related to geography topics. Discusses projects involving (1) environmental science; (2) geology; (3) oceanography; (4) orienteering; (5) weather; (6) U.S. cultures; (7) community citizenship; and (8)…

Provides background material and laboratory procedures for an activity which requires students to compare (in quantitative terms) fossils from 10 localities and to objectively define provinces, regions, and realms. These paleobiogeographic relationships are then used to reconstruct the drift histories of the three continents on which the 10…

Discussed are beach replenishment, and hard structures in relation to the sand transportation system. Failures of current engineering practices and the resulting costs to the taxpayer are stressed. Equations and parameters used to make predictions of beach durability are criticized. (CW)

Gives the background to the philosophy for the introductory teaching of global tectonics and the terrane concept. Provides a discussion of local and general considerations, the curriculum, and terrane tectonics. (RT)

Describes a study on the performance of Internet notes and PowerPoint lecture slides in a physical geology course and compares it with the traditional lecturing method. (Contains 12 references.) (YDS)

Discusses some of the ways that rocks can be used to enhance children's creativity and their interest in science. Suggests the creation of a dramatic production involving rocks. Includes basic information on sedimentary, igneous, and metamorphic rocks. (TW)

Discusses the origin of the catastrophic event as to whether it was an episodic process or of extraterrestrial or endogenous origin. Develops a model of a volcanic mechanism to produce shocked quartz like those found in the Deccan basalts. (MVL)
