PHYSICS TEACHING PRACTICES IN SELECTED UNIVERSITIES IN CZECHOSLOVAKIA, THE FEDERAL REPUBLIC OF GERMANY, FRANCE, THE UNITED STATES, THE UNITED KINGDOM, AND THE UNION OF SOVIET SOCIALIST REPUBLICS ARE COMPARED. REPORTS FOR EACH COUNTRY WERE PREPARED AND SUBMITTED BY A NATIONAL REPRESENTATIVE FROM EACH OF THE COUNTRIES. THE REPORTS WERE REVIEWED BY…

This Child Development Associate (CDA) training module helps interns develop children's science exploration and discovery skills. This process of discovering is known as sciencing. Teachers can create the climate for discovery by becoming actively involved with the children, by sharing the children's natural curiosity about their environment, and…

THE SIXTH IN A SERIES OF 17 VOLUMES, THIS VOLUME PROVIDES THE FOURTH GRADE TEACHER WITH A GUIDE TO THE REORGANIZED SCIENCE CURRICULUM OF THE MINNEAPOLIS PUBLIC SCHOOLS. THE MATERIALS ARE INTENDED TO BE AUGMENTED AND REVISED AS THE NEED ARISES. THIS FOURTH GRADE SUPPLEMENT IS IN TWO PARTS. PART 4A CONTAINS THE INTRODUCTORY MATERIAL, THE CONCEPTS…

Prepared to assist those planning the construction of new science facilities on the elementary, intermediate, or secondary school level. Standards are outlined and specifications detailed. A statement of fifteen general pricniples for planning science facilities in secondary schools precedes a discussion of--(1) special facilities for different…

This presentation of suggested layouts and specifications has been prepared to be of service to school boards, architects, teachers, and administrators who are planning new schools or making renovations to existing structures. The recommendations cover many of the facilities that have been observed in schools throughout the province, and which…

Lists 40 things to do to have a safer chemistry laboratory. Discusses the evolution of these guidelines for schools from safety suggestions originally developed by industry. Categorizes the 40 steps into those requiring minimal cost and those requiring moderate expense. (TW)

Reports the results of a radioactivity survey in England. Discusses the aim of the survey, experimental procedures, analysis, and results. Shows several diagrams, graphs, and tables. (YP)

Demonstrates several objects rolling down a slope to explain the energy transition among potential energy, translational kinetic energy, and rotational kinetic energy. Contains a problem from Galileo's rolling ball experiment. (YP)

Addresses the history and philosophy of accident prevention in chemistry laboratories. Presents the results of a statewide survey done in Colorado designed to investigate the etiology of academic chemistry laboratory accidents in institutions of higher education. Patterns of accident characteristics identified by the student are discussed. (TW)

Addresses the need to present beginning chemistry students with a variety of experiences dealing with chemical reactions to develop the individual student's concept of these processes. Presents information and experiments dealing with the heat effect of chemical reactions. Includes a discussion on exothermic and endothermic processes in laboratory…

Describes the construction of a low-cost (about $70.00) alternative to the commercial fraction collector. Outlines the separate parts of the collector and provides a schematic of electronic circuitry of the instrument. Lists special items required for the development of this project. (TW)

Addresses the introduction of low cost equipment into high school and college physical science classes. Examines the properties of an "ideal" operational amplifier and discusses how it might be used under saturated and non-saturated conditions. Notes the action of a "real" operational amplifier. (TW)

Discusses: (1) Brewster's angle in the elementary laboratory; (2) color mixing by computer; (3) computer iteration at A-level; (4) a simple probe for pressure measurement; (5) the measurement of distance using a laser; and (6) an activity on Archimede's principle. (JN)

A PET microcomputer is used as an accurate and programmable timer to support data acquisition from velocity experiments covering falling, rolling, and sliding objects, and human velocity, acceleration, and power measurements. The inexpensive instrumentation is simple and easy to use and compares favorably with conventional, more expensive…

Presents procedures, demonstrations, activities, and teaching suggestions on topics appropriate for middle school science including a simple electrolysis cell, conversion factors, energy, solubilities of salts, condensers, and a worksheet for studying coppice woodlands. (DC)
