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…

A collaborating scientist--a rewarding addition to any high school science program--can help students collect and analyze data that either replicates or parallels the work of the partnering scientist. This type of partnership is beneficial for both students and scientists, and perhaps there has never been a better time to consider such a…

Described is a report outline for geologic reports. Essential elements include title; abstract; introduction; stratigraphy; petrography; geochemistry; petrology; geophysics; structural geology; geologic history; modeling; economics; conclusions; and recommendations. (Author/CW)

Reports the results of a study of the communication patterns of geophysicists in India, with emphasis on the role of foreign journals. The results are analyzed in terms of information transfer (publication) and information use (citation). (CLB)

Described is an inexpensive and safe laboratory experiment that accurately duplicates the shapes and structures of simple impact craters using fireplace ash, finely ground charcoal, and an air gun. (Author/DS)

Described is a set of FORTRAN programs, suitable for teaching and research purposes, that simulate contact and regional metamorphism. Equations, examples, program uses, and availability are discussed. (CW)

This booklet was prepared by practicing oceanographers to help college students in their search for professional direction. The booklet: (1) points out some frontiers of current research; (2) describes five major subfields of oceanography (marine geology and geophysics, oceanographic engineering, physical oceanography, chemical oceanography, and…

Discusses three research topics which are concerned with eminently practical problems and deal at the same time with fundamental fluid dynamical problems. These research topics come from the general areas of chemical and biological engineering, geophysics, and pure mathematics. (HM)

Discusses the use of remote sensing from satellites to monitor glaciers. Discusses efforts to use remote sensing satellites of the Landsat series for examining the global distribution, mass, balance, movements, and dynamics of the world's glaciers. Includes several Landsat images of various glaciers. (TW)

Refutes scientific creationists' arguments that the earth is less than 10,000 years old by presenting information related to the time scales for creation and evolution models, times from stellar distances, Kelvin's estimate of the earth's age, radioactive decay, radiometric dating, and the decay of the earth's magnetic field. (DC)

Presents a review focusing on techniques and their application to the analysis of geological and inorganic materials that offer significant changes to research and routine work. Covers geostandards, spectroscopy, plasmas, microbeam techniques, synchrotron X-ray methods, nuclear activation methods, chromatography, and electroanalytical methods.…

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)

Presented in table format are student enrollment data for geoscience disciplines at colleges and universities in the United States and Canada. Subfields for both countries include: geology; geophysics; oceanography; marine science; geological engineering; geophysical engineering; geochemistry; hydrology; mineralogy; paleontology; soil science;…

The search for new energy resources as alternatives to fossil fuels have generated new interest in the heat of the earth itself. New geothermal areas with a variety of characteristics are being explored, as are new ways of extracting work from naturally heated steam and hot water. Some of this effort is discussed in this three-part module. Five…

Described is a simple device, that uses a laser beam to simulate P waves. It allows students to follow ray paths, reflections and refractions within the earth. Included is a set of exercises that lead students through the steps by which the presence of the outer and inner cores can be recognized. (Author/CW)
