Describes a three-week summer program teaching selected chemistry faculty how to incorporate polymer chemistry into chemistry courses. In addition to lectures, the program conducted many experiments and provided a trip to industry laboratories. (YP)

A questionnaire and demonstrations were used to identify students' conceptions about the composition of orthogonal velocities. Four questions from the questionnaire are provided and the results for each question are reported. The four implicit vector characteristics of this study are appended. (YP)

Stresses the importance of a reference frame in mechanics. Shows the Galilean transformation in terms of relativity theory. Discusses accelerated reference frames and noninertial reference frames. Provides examples of reference frames with diagrams. (YP)

Provided are two demonstrations for an introductory course in chemistry. The first one emphasizes the observation and the interpretation of facts to form hypotheses during the heating of a beaker of water. The second demonstration shows the liquid phase of carbon dioxide using dry ice and a pressure gauge. (YP)

Describes 10 experiments for characterizing the chromium complex Reinecke's Salt. The properties of the complex, experimental procedures, and a discussion are provided. Analyses are presented for chromium, total ammonia, thiocyanate, ammonium ion, and hydrate water. Measurement methods are described. (YP)

Outlined are materials and testing procedures in which various plant species are screened to determine if they are producing antibiotics. Diagrams are included. (RT)

Reports a method of preparation for tris(ethylenediamine)cobalt(III) and tris(2,2'-bipyridine)cobalt(III) that will shorten the preparation time by approximately 3 hours. Notes the time for synthesis and isolation of compound one was 1 hour (yield 38 percent) while compound two took 50 minutes (yield 71%). (MVL)

Describes an exercise in which students convert lithostratigraphic columns into chronostratigraphic columns, infer paleolatitude using paleomagnetic data, interpret depositional environments, determine the timing of deformation and terrane collision, construct models, and synthesize the results into a geologic history. Background data, procedures,…

Gives the background to the philosophy for the introductory teaching of global tectonics and the terrane concept. Provides a discussion of local and general considerations, the curriculum, and terrane tectonics. (RT)

Describes an experiment in which a tumbler is used to simulate the changes that pebbles undergo during stream transport. Provides information on a discussion of results, equipment needed, an additional assignment, and a list of references. (RT)

Provides an introduction and explanations of stress-strain relationships, measuring stress, a goal of structural analysis, and legitimate applications of the concept of stress. Diagrams include a derivation of the stress tensor, graphical representations of stress-strain relations, and related problems. (RT)

Describes the design and logistics of a one-month, 1600 km bicycle tour field trip in which the travel, not the stops, is the major teaching tool. Provides a map and a summarized itinerary of the geology experience of southern California and Nevada. (RT)

Describes a computer program which represents the first merger of an expert system and imaging technology into a tool to assist in learning mineral identification. Presents a discussion of the system's development, evaluation of effectiveness, and future modifications. (RT)

Recounts the development of the National Association of Geology Teachers from its conceptual stage of origination at Wauwatosa, Wisconsin. Reports on: the publication of the "Journal of Geological Education" which began in 1951 and now commands a circulation of approximately 2600, a good financial standing, and a growing membership. (RT)

Discussed are some of the uncertainties in human genetic mechanisms that are often presented as dogma in Biology textbooks. Presented is a brief historical background and illustrations involving chromosome abnormality in humans and linkage studies in humans. (CW)
