A series of three investigations are developed utilizing earthquake data and a calculator system with a card reader, X-Y plotter and printout device. The investigations involve determining the spatial distribution of earthquake hypocenters with the goal of having students work with realistic data. (DF)

Describes a method used to teach the concept of radiometric dating using mathematical equations. Explores the lack of information in textbooks on how to solve radiometric dating problems using mathematical concepts. (SAH)

Describes a plexiglass and aluminum model of a Wadati zone suitable for classroom exercises and demonstrations in earth science to let students test the hypothesis that earthquake hypocenters near oceanic trenches tend to occur along planes that dip away from the trenches, toward associated island arc or continental mountain chain.

This is a 53-page cumulative index to the Journal of Geological Education. Ninety-three categories are included and the contents are intended to be more accessible to readers with the establishment of the standard subject matter indexing categories. (Author/SA)

Provides a list of references on creationism divided into six parts covering: books and collections of articles; articles on geological aspects; articles on physics and biological aspects; articles on philosophical and religious aspects; articles on educational, legal, sociological, historical, and public policy aspects; and major creationist…

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)

Points out that the most basic of creationist attacks of geology, their claim that uniformitarianism is an unreliable basis for interpreting the past, fail because the uniformitarianism they describe is no longer a part of geology. Indicates that modern uniformitarianism is merely the philosophical principle of simplicity. (Author/JN)
