Reviews eight research studies and one survey pertaining to the ESCP instructional package. Areas concerning ESCP in need of further research are discussed through the aid of an instructional sequence model. An extensive bibliography is included. (LC)

The nature of the earth's core is described. Indirect evidence (such as that determined from seismological data) indicates that it is an iron alloy, solid toward its center but otherwise liquid. Evidence also suggests that it is the turbulent flow of the liquid that generates the earth's magnetic field. (JN)

The nature and dynamics of the earth's mantle is discussed. Research indicates that the silicate mantle is heated by the decay of radioactive isotopes and that the heat energizes massive convention currents in the upper 700 kilometers of the ductile rock. These currents and their consequences are considered. (JN)

Conductiometric titrations can be used to simulate subduction-setting volcanism. Suggestions are made as to the use of this technique in teaching volcanic mechanisms and geochemical indications of tectonic settings. (JN)

The elimination of traditional courses in favor of student-originated, self-graded projects in the Department of Geology and Geography at St. Lawrence University in Canton (New York) proved too radical for the entire faculty. The program eventually became two-tracked, offering students both traditional and student-generated learning situations.…

Highlights major science news stories of 1982 reported in "Science News." Categories include space/astronomy, biology, chemistry, medicine, energy, physics, anthropology/paleontology, earth sciences, technology, behavior, science/society, and the environment. (JN)

Spurred by National Aeronautics and Space Administration (NASA) technological advances, a budding industry is manufacturing equipment and providing services toward better management of earth's resources. Topics discussed include image processing, multispectral photography, ground use sensor, and weather data receiver. (Author/JN)

Reviews an educationally valuable and reasonably well-designed simulation of volcanic activity in an imaginary land. VOLCANOES creates an excellent context for learning information about volcanoes and for developing skills and practicing methods needed to study behavior of volcanoes. (Author/JN)

Describes a simple, student-oriented method of determining seiches and compares actual to theoretical results. Includes information about equipment needed, data gathering, and analysis of the data. (Author/DS)

The authors investigated a science course which was divided into two sections, one "student-structured" and one "teacher-structured." Data indicate that the "student-structured" environment enhanced the students' desire to participate in scientific activities, and their belief that they were capable of doing so. (JT)

Describes an interdisciplinary course which focuses on the grassland area of the central United States. Study of the land is approached through: (1) literature dealing directly with land; (2) novels about land-dependent people; and (3) formal lectures on geology and natural history of grassland. (Author/MA)

Describes a simple seismograph which can be built quite easily and is sufficiently sensitive to record earthquake waves at home. (HM)

The classroom demonstration using ammonium dichromate to simulate a volcanic eruption can be modified into a more dramatic and accurate representation of the geologic processes involved in the formation of a volcanic crater. The materials, demonstration setup, safety procedures, and applications to instruction are presented. (Author/WB)

Presents a summary of each paper presented at the Lunar and Planetary Science Conference at the Johnson Space Center, Houston in March 1980. Topics relate to Venus, Jupiter, Mars, asteroids, meteorites, regoliths, achondrites, remote sensing, and cratering studies. (SA)
