The importance of analyzing laboratory situations in a technical school special needs area is increasing rapidly. Such a system is essential for objectively analyzing the content of laboratories and describing the tasks performed there in a standardized and easily understood manner. The laboratory description can be easily used to provide program…

General and specific safety procedures and recommendations for secondary school science laboratories are provided in this guide. Areas of concern include: (1) chemicals (storage, disposal, toxicity, unstable and incompatible chemicals); (2) microorganisms; (3) plants; (4) animals; (5) electricity; (6) lasers; (7) rockets; (8) eye safety and…

Laboratory experiences as a part of most U.S. high school science curricula have been taken for granted for decades, but they have rarely been carefully examined. What do they contribute to science learning? What can they contribute to science learning? What is the current status of labs in our nation s high schools as a context for learning…

Describes several common synthetic organic transformations involving alkenes, alcohols, alkyl halides, and ketones. Includes concepts on kinetic versus thermodynamic control of reaction, rearrangement of a secondary carbocation to a tertiary cation, and the effect of the size of the base on orientation during elimination. (MVL)

Describes the design and materials for an elementary school science laboratory which can be installed for approximately $3,000. (MLH)

The teaching laboratory in physics departments in colleges and universities is a source of great potential strength in undergraduate education. Recent surveys and conferences, have identified inadequate teaching equipment and laboratory development. This report reviews these problems and offers suggestions for an enhanced federal effort to solve…

Discusses an experiment on friction to illustrate the "law" governing the relationship of the friction force to the volocity of air track cars. (CC)

This document provides abstracts of 116 laboratory experiments/demonstrations currently being utilized in all areas of engineering education at 52 universities across the United States. (SL)

Describes the experimental arrangement for x-ray analysis of samples which involves the following: the radioisotopic x-ray disk source; a student-built fluorescence chamber; the energy dispersive x-ray detector, linear amplifier and bias supply; and a multichannel pulse height analyzer. (GS)

Findings of two recent surveys on safety equipment in laboratory facilities are presented. The first survey was a pilot study of emergency shower and eye wash equipment. This study was followed by a more comprehensive random survey of safety equipment in 2,820 labs. Among other findings, the surveys indicate that many plants are underequipped, or…

This laboratory manual, part of a series of instruction books on basic experimental chemistry, is designed to provide the secondary school students of developing countries in Asia with laboratory experiences that bring out the fundamental concepts and ideas of chemical kinetics. Taking into consideration the possibility of limited facilities of…

This document is a first-person account by the mathematics coordinator at Temple University dealing with the segment of the TTT (Trainers of Teacher Trainers) project held at the Reynolds Elementary School. The stated purpose of this segment was to provide on-the-job experience in the area of elementary school mathematics. The basic program…
