Describes the results of the Viking lander's analyses of the Martian soil. Implications of these results are also included. (MA)

The development of the Crustal Evolution Education Project (CEEP) is discussed from a historical perspective. John Dewey's Laboratory School and Ralph Tyler's Rationale are included. (MA)

A review of this year's studies of the lunar core samples is presented. Included are some current interpretations and some suggested areas for further research. (MR)

This article suggests the use of geothermal energy for producing electricity, using as an example the development at Wairakei, New Zealand. Other geothermal areas are identified, and economic and environmental co sts of additional development are explored. (Author/AV)

Argues that earth scientists must be competent in a wide spectrum of disciplines, must be discouraged from early specialization, and must be well trained in mathematics, physics, and chemistry. (SL)

Argues that the measure of the relationship between width and depth in stream sections in introductory geology courses should be referred to as the width-depth (W/D) ratio, and that the term form ratio should not be used. (SL)

Describes duplicating black and white transparencies inexpensively into color, using diazochrome film. (SL)

Provides the theory behind the construction of a classroom seismograph. Data obtained from such a device is presented. (CP)

Provides a conceptual framework on which to build a multidisciplinary approach to environmental education. (See related document SE 520 333.) (CP)

The authors suggest ways in which the gravity model can be used in high school geography classes. Based on Newton's Law of Molecular Gravitation, the law states that gravitation is in direct ratio to mass and inverse ratio to distance. One activity for students involves determination of zones of influence of cities of various sizes. (Author/AV)

Describes activities by which the porosity and permeability of materials with respect to water can be measured. (CP)

In this exercise, students examine Aristotle's weight hypothesis by testing variously shaped marble chips. These chips are weighed and dropped down a water tube. Average fall times and weights are recorded and graphed. Students are asked to apply this information to rock and soil deposition by streams. (MA)

Promotes the study of ancient rocky shores by showing how they can be recognized and what directions future research may follow. A bibliography of previous research articles, arranged by geologic period, is provided in the appendix to this paper. (CW)

Describes the background of schemes to rationalize earth science departments in the United Kingdom. Discusses the rationale of these schemes and the controversy they have caused in the academic community. (CW)

Presents a three-part exercise which provides undergraduates with opportunities to work with data related to the earth's magnetic field. Includes student materials for activities in determining the history of the earth's magnetic field, in finding the general pattern of declination, and for looking for a polar reversal history. (ML)
