Presents three simple distinct operational procedures for transforming the empirical notion of speed into a formal concept. The relationship between these three procedures and Galilean velocity and Einsteinian relativity is also included. (HM)

Describes a physical geology assignment in which students are required to keep a journal of their daily observations, impressions, and questions which come to mind about the Earth. Presents the role of the journal, outlines the criteria for evaluation, and provides samples of student reaction to the assignment. (GS)

Lists the materials and outlines the procedures for mounting maps on cloth to make the maps weatherproof, more durable, and easier to handle. (GS)

Lists 50 riddlelike questions and answers based on the common names of rocks and minerals. (GS)

Updates the results of a six-year experimental course in physics whose goal was to translate the physicist's approach to science into an approach to the teaching of physics. Provides a course description and rationale and outlines the instructional procedures used. (GS)

Describes the analysis of geology teaching assistant reaction to a training program on teaching techniques utilizing videotaped teaching episodes. Reactions of the participants indicate that the use of videotaped teaching episodes in conjunction with group discussion is one way to improve their teaching practices. (Author/SA)

Describes several science fiction stories that may be useful, due to their relevance to geology, to promote discussion in the science classroom. Suggestions for specific discussions are given. (SA)

Described is a procedure for the study of condensation polymerisation. The objectives of this study are to help students understand concepts that are somewhat abstract in nature (i.e., polymerisation) through derivation of equations that help to describe and predict the particular phenomena. (CS)

Describes a project on the application of the laser which aims to stimulate the interest of undergraduate students in applied physics and to demonstrate the interaction between light and ultrasonic waves by building a simple laser communication system. (SK)

Listed are field stations in the Caribbean and Florida-Bahamas which are suitable for classes in field geology and tropical marine science. Each field station is described by listing the name of the institution, description of accommodations, library facilities, laboratory facilities, boats, classrooms, motor vehicles, study areas, scuba, and…

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)

Describes a straightforward vertical fall experiment using a badminton shuttlecock, a tape measure, and a millisecond timer. The effects of air resistance are important and directly measurable. The experimental data best fit a predictive model which assumes a resistive force quadratic in the instantaneous speed of the falling object. (GS)

Discusses the difficulties and challenges of doing basic research in science in a research university. Emphasizes the need for revising the Office of Management and Budget's Circular A-12 which imposes regulatory demands and work-load documentation on government-sponsored research in universities. (CS)

Deals with trends arising from decreasing amount of descriptive chemistry being taught. A course outline is suggested, and general and specific aims are mentioned. Some detailed examples of models of thought, which should replace theories, are suggested and the future of syllabi is briefly discussed. (Author/JN)

Describes the use of infrared and atomic absorption spectrometry in an introductory chemical oceanography course to introduce students to carbonate mineralogy by having them determine both the crystal structure and the magnesium content of seashells that they have collected. (Author/JN)
