Described is an activity in which students locate the epicenter of several earthquakes, plot the trends of the two faults involved, and determine the sense of motion along the plane of the two faults. Provided are objectives, background information, procedures, and data necessary for the activity. (CW)

Presented is an activity in which a mystery setting is used to motivate students to construct their own decay curves of melting ice used as an analogy to radioactive decay. Procedures, materials, apparatus, discussion topics, presentation, and thermodynamics are discussed. (CW)

This paper focuses on both the implicit assumptions and biases in chemistry curricula and the institutionalized influences on women's participation in science-related courses and careers. Stereotypes of science and femininity and the use of the feminine perspective in teaching science are discussed. (CW)

Develops a programed approach for developing design projects. Describes the initiation, design experiences, final report, and problems of the approach. (YP)

Argues about the conclusion that bigger science departments are more productive than smaller ones. Indicates the conclusion cannot be supported by the data. (YP)

The use of taxonomic scales to assess the level of student cognitive development and thinking skills, and to structure instruction is discussed. One instructor's method is presented. Perry's taxonomy is graphically illustrated. Sources for five assessment instruments are listed. (CW)

Describes general and specific didactic profiles of engineering courseware for evaluating a curriculum. To carry out a diagnosis of written material, the two profiles and a complexity facet were prepared. Provides a model in the self-instructional course, Digital System. (YP)

Presented is an accounting of known numbers of major categories of life, from viruses to mammals. The construction of the census is described. Included are living and nonliving species and genera. (CW)

Applications of lasers to molecular absorption spectrometry, molecular fluorescence spectrometry, visible semiconductor fluorometry, atomic absorption spectrometry, and atomic fluorescence spectrometry are discussed. Details of the use of the frequency-doubled diode laser are provided. (CW)

Examined is the possibility of applying industrial principles of quality assurance to engineering education. Describes an industrial quality assurance model emphasizing the assessment criteria of the quality of performance and capability. (YP)

Analyzes a "Time" article discussing genetics and bioethics to evoke the need of scientific literacy education. Suggests reform in teacher education programs. (YP)

The construction of a hydroponic system for use in the classroom is described. Provided are construction details, a list of materials with approximate cost, a diagram of the setup, and a sample test. Several activities are suggested. (CW)

Discusses a "process control" course in undergraduate chemical engineering. Describes current practices and philosophy and an outline for a course to be taught in the future. Appended are summaries of 12 participants' discussion. (YP)

Presents some principles for specifying general classes of polymers for predicting relative chemical attack from acids, bases, oxidants, and certain common antagonists. Also discusses predicting relative solvent effects. Suggests uses of this information in two or three lectures in a chemical engineering materials course. (YP)

The porphyrias are a family of genetic disorders whose genetics and biochemistry are largely identified. Background information on these diseases are discussed including porphyrins, gene expression, population genetics, and historical significance. (CW)
