Describes a computer-based instructional model for the physiology laboratory. Attempts to develop an efficient and low-cost system designed to provide dynamic student/machine interaction are discussed. (MA)

This symposium focused on the question: can colleges afford to continue offering high quality laboratory instruction at the undergraduate level. (Author/BB)

The purpose of this paper is to present problems (and solutions) from the areas of marketing, population planning, system reliability, and mathematics to show how a computer simulation can be used as a problem-solving strategy in probability. Examples using BASIC and two methods of generating random numbers are given. (Author/MP)

Describes an oscillating chemical reaction, and discusses numerous parallels to it in research, such as in fibrillation of the heart, body-clock rhythms of animals and plants, the self-assembly of multicellular organisms, and certain stripes in volcanic rock. (GA)

Presents a calorimetric experiment designed to clarify some of the basic physics of heat transfer and insulation. (GA)

Explains the idea that a half-length mirror is sufficient to view the whole length, regardless of distance. (GA)

Describes the intuitive approach used in general chemistry and points out its pedagogical advantages. Explains how to extend it to acid-base equilibrium calculations without the need to introduce additional sophisticated concepts. (GA)

Describes a simple inexpensive experiment designed to measure the levels of cortisol in a serum or plasma sample. (Author/GA)

Describes three experiments to demonstrate several aspects of artificial radioactivity. Metal foils were activated, using slow neutron bombardment. (GA)

Describes a simple method for measuring the heat of vaporization of water, which gives results within five percent of the accepted value. (GA)

Describes a laboratory game called SUPERCHARGE, used as an aid to help students understand the concept of equipotential surfaces generated by distributions of charges. (GA)

Describes an experiment for measuring the lifetime of the 60-keV state in 237-Np which is populated in the alpha decay of 241-Am. The technique used is the delayed coincidence method using a time-to-pulse-height converter. (Author/GA)

Describes an experiment in nuclear physics to study radioisotopes. In this experiment the build-up of the activity of the source, 28-A1, is done first by irradiating it. (GA)

Discusses two different uses of information theory in chemistry to present entropy and chemical structure analysis. (GA)

Experiments and demonstrations are presented which have been used in a high school course on animal behavior. Animals used include spiders, fish, birds, and mammals. (BB)
