Presented is a lesson designed to demonstrate the concept of telepresence to students. Provided are objectives, teacher preparation, procedures, and a sample debris field grid. (CW)

Described is an experiment which may be carried out quickly using tungsten-filament irradiation. Materials, experimental procedures, and results are discussed. Procedures for filtration on silica gel are appended. (CW)

Presented is the course outline and proposed science content for this course. The structure, sessions, and evaluation of the course are discussed. (CW)

Described is a method which can be used to teach children how to study science. Included are suggestions for efficient use of the textbook, how to learn in the laboratory, hints for note-taking, how to ask questions, and how to study for tests. (CW)

Described is a project designed to transport a rich fossil-bearing bed of rock to the campus of a community college for analysis by undergraduate students. The arrangements, set-up acquisition of rock, transportation, and costs are discussed. The benefits of this arrangement are highlighted. (CW)

Described is a 35mm projector demonstration which combines the advantages a highly magnified view of the sample zone as it undergoes dispersion and the ability to show more than a single-line flow injection analysis manifold. Manufacture and use of the slide for demonstration are discussed. (CW)

The materials needed and the procedures for construction of the apparatus are detailed. Two experiments that use this equipment are suggested. Criteria for operation are listed. (CW)

Some observations of general progress and of gender-related differences in achievement when using construction sets in the early years are presented. Included are the results of two studies which examined the use of Lego construction sets by children age six to eight. (CW)

Outlined is the development and use of oxidants for use in elementary organic chemistry classes. Discussed is the oxidation of alcohols to carbonyl compounds, and the oxidation of primary alcohols or aldehydes to carboxylic acids. (CW)

Described are efforts of the Open University (United Kingdom) to retrain physics teachers using distance learning strategies. Discussed are the teacher shortage, the program design, styles of delivery, group activities, content, teacher types, and the National Curriculum. (CW)

Described are simple experiments designed to demonstrate the effect of some factors of the environment (dryness, temperature, and fungicide application) on the size of some populations of soil microorganisms. Materials, media, techniques, procedures, and results are discussed. (CW)

Described is how spreadsheet and problem solver microcomputer programs may assist students in performing mathematical calculations. Discussed is the application of the equation solver "MathCAD" to various areas in the undergraduate curriculum. (KR)

Described is the five-week Governor's School course emphasizing chemical reactions for high school seniors. Students took two courses: a subject concentration in humanities or science and a global issues course. The course format included both lecture and laboratory activities. (KR)

Presented are five examples of the application of computer technology to undergraduate chemistry instruction. Topics include: an interface for kinetic experimentation; theoretical calculations; automation of chemical techniques; searching the chemical literature; and Huckel molecular orbitals. (CW)

Discussed are the construction and uses of a version of a photoelectric colorimeter by students. Included are materials needed and four experiments which use the equipment. Sample results are shown. (CW)
