Stressed is the interrelationship among the three major groups of sedimentary rocks and the potential benefits in understanding of sedimentary processes to be gained by a petrosynthesis. Listed are 59 references. (CW)

Describes a technique for making reflectance measurements of opaque minerals in polished thin sections. Provides a calibration procedure, reflectance values for common opaque minerals, and a graph showing an example calibration curve of minimum shutter speed of opaque minerals versus published reflectance data. (RT)

Discusses magnetic polarity stratigraphy as a tool for correlation of fossiliferous terrestrial deposits. Explains the strengths, weaknesses, limitations, preferred conditions, sampling, laboratory analysis, and applications of this technique. A table of paleomagnetic studies on vertebrate-bearing terrestrial sections arranged by age and locality…

Describes a course teaching planetary science to elementary school students in collaboration with a university. Chronicles how a partnership between an elementary school teacher and a university-based research scientist effectively shaped the teacher's understanding of values and attitudes inherent in science education. Presents a model for…

Describes the Multidisciplinary Studies program at the University of Massachusetts Dartmouth that provides advanced coursework in the sciences without requiring that a student major in a specific science. Focuses on the fields of environmental science, cognitive science, gerontology, and environmental psychology. (JRH)

Presents a thorough overview of earthquakes in New Zealand, discussing plate tectonics, seismic measurement, and historical occurrences. Includes 10 figures illustrating such aspects as earthquake distribution, intensity, and fissures in the continental crust. Tabular data includes a list of most destructive earthquakes and descriptive effects…

Presents a mathematical explanation for the development of tidal activity. (MVL)

Examined is the science of catastrophism and its role in planetary and earth science. The effects of impacts on earth with extraterrestrial origins are discussed. Perspectives on the age and dynamics of the earth's crust are presented. (CW)

Describes the use of a radio telescope to arouse new interest among students. The article partitions into the following sections: (1) Radio Astronomy--Which Level; (2) First Steps: The Site--The Antenna; (3) The Electronics: Do It Yourself, or Store Bought; (4) Field Test: Music of the Spheres; (5) Getting Started: Entry Level Projects; and (6)…

Describes a learning module designed to help students use the factor labeling method in problem solving. (ZWH)

Presented is a cooperative learning activity in which students assume different roles in an effort to produce a relief map of the ocean floor. Materials, procedures, definitions, student roles, and questions are discussed. A reproducible map for the activity is provided. (CW)

Described is how an ordinary FM radio or television receiver can indicate when a meteor streaks overhead by receiving distant broadcast signals. Temperature inversions and the presence of ionized clouds can also be detected using receivers. Information on the troposphere and ionosphere and directions for the activity are included. (KR)

Information on how a shortwave radio can be used to make empirical observations about solar activity and the Earth's geomagnetic field is provided. How to interpret transmissions of shortwave propagation information, weather conditions, and highly accurate time signals from shortwave stations is discussed. (KR)

Describes how the geology department of Bucknell University integrated its Senior Program with Bucknell's writing program. The program stresses the importance of the following: (1) teaching appropriate writing skills and style; (2) providing clearly articulated writing assignments; (3) writing multiple drafts; (4) using the peer-review method; and…

Discusses a variety of writing assignments emphasizing critical-thinking skills for a geology curriculum. The assignments include question and answer assignments, reaction papers, short papers, and position papers. The authors contend that several short writing assignments are better than a single term paper because students improve their writing…
