Describes a multichannel analyzer built using eight-bit S-100 bus microcomputer hardware. The output modes are an oscilloscope display, print data, and send data to another computer. Discusses the system's hardware, software, costs, and advantages relative to commercial multichannels. (Author/GA)

Describes a laboratory exercise to demonstrate enzyme activity using gelatin and meat tenderizer. The exercise is adaptable to any grade level. (MA)

Some possible uses of math lab materials and activities that are natural and appropriate to the development of process skills are explored through a discussion of a geoboard activity. (MP)

Discusses the possibilities and the potentials of advancing the state of the art in computer chemistry. Explains that the fears will be extrapolating new compounds from existing ones, and predicting new activities based on chemical structure. (GA)

The authors present an alternative model for training in organizational development (OD) which differs from other such models by being eclectic, inexpensive, and applicable to participants with varying degrees of experience. A design for a training laboratory is elaborated and related to theories about OD and about learning processes. (SK)

Presents an overview of the construction techniques of dye lasers suitable for student projects and briefly describes possible laboratory projects. (JN)

Capsulizes the main premises of the articles in the UCLA Educator Winter 1980 issue on laboratory schools (EJ 228 397-405), focusing on issues of mission, support, and laboratory schools in a nonuniversity setting. (CAM)

Describes an experiment to measure the thermal conductivity of some gases in an undergraduate physics laboratory using a hot wire method in the pressure range ten to one torr. (HM)

Describes the infrared analysis of geological specimens which can form the basis of a laboratory exercise, allowing some minerals to be identified by "fingerprint" technique. Students can gain insight into the concept of symmetry and environment around an atom. (Author/SA)

Provides guidelines prepared by the National Science Teachers Association for the use and care of invertebrate and vertebrate animals in the classroom. Suggestions are made for conducting experimental and observational studies. (CS)

Describes programs for the gifted: visual and performing arts for secondary students, enrichment for rural elementary students, and a learning center elementary enrichment program. NOTE: includes "INTERARTS: The High School Program for the Talented in the Arts" by Barbara Luehning, "Spice" by Jane V. Salisbury, and "Learning Center Enrichment…

Explains how CTR Wilson cloud chamber experiments can be simulated with simple low-cost apparatus. Described are the Wilson cloud chamber, colour rings, measurement of rings, and the apparatus. (DS)

This study provides experimental evidence that noise intensities typical of those found in vocational education laboratories are detrimental to student performance. As noise intensities increase in the learning environment, the time required to complete assigned tasks increases. (SK)

Describes methods for studying the direct effect of thyroid hormones on the induction of metamorphic change in amphibians. (CS)

Presents a set of experiments that explore variables within the steps of the filtration process. (CS)
