Presents a chemical instrumentation laboratory experiment that introduces the methodology of the fabrication and evaluation of an ion-selective electrode. (CS)

Presents methods by which undergraduate students gain practice in ESR spectroscopy. (CS)

An approach is suggested for teaching science history through inquiry training. A series of investigations are given for illustrating to students the manner in which organisms are grouped taxonomically. (SA)

Describes a simple, inexpensive Faraday balance for studying the effect of a strong magnetic field on selected reaction rates. Aschematic diagram detailing the essential features is included. (BT)

Continued from an earlier paper are more descriptions of microcomputer systems and applications in chemical education. A number of microcomputer systems are compared. Also listed are five recent references which review popular microcomputers. (Author/CS)

The experiment described is intended to illustrate the intermolecular phenomena involved in association colloids. These are normal and inverse micelles and lyotropic liquid crystals. Solubilization, microemulsion and emulsion are discussed. (Author/SA)

A solar project for sixth grade students is described and diagrams and photographs are included. Construction of four solar collectors is suggested as a valuable learning experience. (SA)

The origin of the design of model rockets and spaceships based on Universal Studio's, "Buck Rogers in the 25th Century" is described. (SA)

Describes a study unit on the Titius-Bode Law of planetary distances designed to be used in undergraduate astronomy courses. The format of the guide is based on a Piagetian learning cycle of exploration, conceptualization, and application. (HM)

Presents two methods for measuring the index of refraction of glass or lucite. These two methods, used in the freshman laboratory, are based on the fact that a ray of light inside a block will be refracted parallel to the surface. (HM)

This is a description of a beginning college biology course for visually impaired students. Equipment for instruction is discussed and methods for using the materials are included. Topics included in the course are chemical bonding, diffusion and osmosis, cell structure, meiosis and mitosis, reproduction, behavior, nutrition, and circulation. (SA)

Presents an activity on metrics for elementary children which utilizes newspaper comic strips. Children are asked to write humorous metric captions to match the pictures. (SA)

Discusses the variety of ways to explore sounds in the natural and man-made world with children. Activities are given for use in learning centers. (SA)

This experiment demonstrates the polarization properties of the transition moment, vibronic activity in an excited state, cyrogenic techniques, crystal site splitting, and the use of mixed crystals. (BB)

Presents nine selected chemistry notes which could be used in school chemistry courses. Each includes the name of the author, a description of activities suggested and a list of references. (HM)
