A group of high school students (XII Liceum) in the framework of the Roland Maze Project has built a compact telescope of three Geiger-Muller counters. The connection between the telescope and a PC computer was also created and programmed by students involved in the Project. This has allowed students to use their equipment to perform serious…

This monograph is intended to guide teachers of water resources, technicians and university students in establishing physical facilities which can introduce learners to methods, techniques, and instruments used in water resources management and assessment. It is not intended to serve as an exhaustive list of equipment and their descriptions or as…

This document provides technical information and simple instructions for constructing 84 different pieces of science equipment. Each entry includes: (1) name of item; (2) purpose of the equipment; (3) person who submitted the information; (4) line drawing of prototype; (5) list of low-cost materials needed; (6) construction procedures; (7)…

This report presents information from phase I of a survey designed to develop quantitative indicators of the current national stock, cost/investment, condition, obsolescence, utilization, and need for major research instruments in academic settings. Data for phase I (which focused on the physical and computer sciences and engineering) were…

The purposes of this study were to determine how experienced high school physics teachers were in using computers, how computers were being used for high school physics instruction, what the teachers perceived the use of computers in their physics classes should be, and what the enabling and constraining factors were in developing the use of…

This paper describes the events following the news of Oersted's discovery of the effects of a current of electricity on a magnetic needle. It focuses on Biot and Savart's law which expresses the force between a current element and a "molecule of magnetism" that can be deduced from Ampere's law of interaction between two current elements.…

THIS GUIDE IS DESIGNED TO ASSIST ELEMENTARY AND SECONDARY TEACHERS, SUPERVISORS, AND SCHOOL ADMINISTRATORS IN THE PURCHASE OF SCIENCE AND MATHEMATICS EQUIPMENT. ITEMS ARE LISTED ALPHABETICALLY AND ARE CLASSIFIED AS BASIC, STANDARD, OR ADVANCED. DESCRIPTIONS INCLUDE (1) SCHOOL SUBJECTS IN WHICH THE ITEM IS USED, (2) THE MAJOR USE OF THE EQUIPMENT,…

Twenty-two projects are described in this booklet. Materials necessary for construction can be obtained for little cost or as salvaged parts. Equipment produced by these projects can be used in the collection and study of plants and animals and in the study of environmental quality parameters such as air quality and soil conditions. Construction…

An outline of a conference paper on planning for science facilities provides a reference list of areas and procedures to be considered. The major categories include--(1) the planning stage, (2) the planning committee, (3) the philosophy of science education, (4) the type of facility to be built, (5) facilities and spaces required, (6) information…

This book is intended to serve as a source of ideas for devising simple scientific activities, investigations, and experiments and for the construction of necessary equipment using available materials. This revision of an earlier edition reflects modern approaches to science teaching at the elementary and secondary school levels. This edition has…

The document is a versatile publication providing an outdoor education aid for teaching elementary (beginning with grade 4), high school, and college students. The process is one of learning by doing; i.e., the students construct their own instruments for field studies. The book presents over 100 ideas in an easy-to-follow, easy-to-use format.…

Discusses the use of astrological signs as a vehicle for getting students interested in astronomy. Describes the construction and use of simple stellaphane starframes that can be used to locate astrological constellations. Provides instructions for photographing constellations with a 35 millimeter camera. (TW)

Provides the results of an annual review of nontechnical astronomy books written for readers without extensive background in science or mathematics. Includes reviews of books on topics including amateur astronomy, comets, computers, cosmology, galaxies, pseudoscience, the solar system, space exploration, stellar evolution, telescopes and…

Introduces a photogate arrangement using a photo-reflective sensor for air track experiments. Reports that the sensitivity to sunlight can be eliminated and a mechanically more convenient package produced. Shows the mounting, circuit, and usage of the photogate. (YP)

Describes a program to support lectures on analytical centrifugation, and to illustrate the manner in which useful analytical data about macromolecules can be obtained from simple centrifugation studies without the need for mathematical expertise. Discusses the background, methods, calculations, and results involved in this activity. (CW)
