By experimenting with measurement on regular and irregular surfaces, students can give an appreciation of the nature of the measurement process. (SD)

Describes an undergraduate experiment that illustrates the use of thin-layer chromatography. (MLH)

Using mirrors mounted on a plywood base to study reflections provides an introduction to the study of transformation. (SD)

Activities involving rolling dice and recording results in diverse ways introduce children to a variety of basic mathematical concepts. Several games and activities are described. (SD)

The evolution of a laboratory oriented undergraduate plasma physics course is described. Brief accounts of the 14 experiments utilized in the course are provided. (CP)

Describes experiments, demonstrations, activities and ideas relating to various fields of chemistry to be used in chemistry courses of secondary schools. Three experiments concerning differential thermal analysis are among these notes presented. (HM)

Two specialized facilities to produce cells and cell components on a large scale for scientific research have recently been established by the National Science Foundation. (BB)

Two statistical tools, the Chi-square and standard error approaches, are compared for use in Mendelian genetics experiments. Although the Chi-square technique is more often used, the standard error approach is to be preferred for both research investigations and student experiments. (BB)

Using aerial photographs to study shrubs biomass allows students to avoid unpleasant working conditions and to study communities that are inaccessible or distant. (BB)

Describes a laboratory structure based on the open classroom model, consisting of various "skill stations," such as the "listening comprehension and pronunciation station," and designed to allow for flexibility, stimulation, variety, and contact between teacher and student. (AM)

Presents several new products and equipment for teaching college science courses such as the electronic toploading balances and the hologramaker. A description of each product, cost, and addresses of manufacturers are also included. (HM)

Reports on a part of a report on primary schools in England. States that science instruction tends to be superficial, and that the teaching and the content require more planning. (GA)

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 session focused on the types of chemistry courses taught in the high schools and the financial support of high school chemistry labs. (BB)
