Investigates the possibility of using audio-tapes for self-study courses in technical colleges. This article presents: (1) description of the electrochemistry course taught; (2) results of the assessment of student reaction to the course; and (3) conclusions. (HM)

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)

Discusses free-radical organic conductors and semiconductors, contrasting them with familiar classes of solids such as metals, magnetic insulators, and molecular solids. (Author/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)

Discusses the kinetic behavior associated with the interaction of metal ions with apocarbonic anhydrase, focusing on the formation of two metallocarbonic anhydrase--the biochemically active Co(II) and the inactive Ni(II)derivatives. (GA)

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

Describes the college level experiments: a simple measurement of the isotopic abundance of 40-K, a mechanical experiment, on kinetic energy, and on soap films between wedged plates. (GA)

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

Describes a flexible course structure in physics that allows the transfer of students between different programs, up to the end of second year of study. (GA)

Describes a demonstration of P and S (longitudinal and transverse waves), using students' bodies as media, to explain seismic waves in a geology course. (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)

Describes the following: an electric circuit for an expensive photometer, an amplifier circuit capable of demonstrating many aspects of behavior of free and driven oscillators, and finally a projection recording system which uses an unmodified XY or XT recorder and a separate overhead projector.
