The law of conservation of momentum is one that students often have difficulties understanding. This experiment allows students to use childhood toys to examine and calculate the muzzle velocity of their favourite water gun by using an air track, a spark timer or data logger and the law of conservation of momentum in a one-dimensional case, a…

A laboratory project for a first semester biochemistry course is described, which integrates the traditional classroom study of the structure and function of biomolecules with the laboratory study of these molecules using fluorescence spectroscopy. Students are assigned a specific question addressing the stability/function of lipids, proteins, or…

This document provides teachers with sources of useful information and new ideas about the high school chemistry laboratory program. Chapters included are: (1) "Introduction" describing the philosophy and specific objectives of this project; (2) "Importance of Laboratory Work"; (3) "Chemistry Lab Outline" listing…

This manual was written as an aid to teaching assistants (TAs) who conduct the laboratory portions of life science courses at the University of Washington. In general, this manual does not present specific factual material. Rather, it offers suggestions on how to handle various teaching situations and provides a framework to use in many different…

The purpose of this brochure is to introduce teachers to the University of Hawaii's language laboratory facilities and services. Key features built into the laboratory are student cartridge decks and the dual-teacher console. The procedures and functions of the language laboratory are described in three major sections: (1) student facilities, (2)…

Described is an experiment used in an undergraduate biochemistry laboratory involving inducing rickets in chicks and correlating the disease to a reduction in vitamin D-dependent calcium binding protein. Techniques involved are hormone induction, protein isolation, and radioisotope methodology. (Author/DS)

A trainerless laboratory model wherein the trainer never attends is presented. The discussion includes the advantages and disadvantages of the model, evidence for its effectiveness, and implications for the future of training. (Author)

Describes the development of a laboratory training program with unusual promise for social change in the Dominican Republic. (AN)

Discusses ways to cut rising energy costs within university laboratories by using heat recovery systems and variable volume exhaust hood systems. Explores the implementation of broad-based, sustainable laboratory classroom design concepts. (GR)

A number of laboratory exercises for the organic chemistry curriculum that emphasize enantioselective synthesis of the aldol condensation which involves the proline-catalyzed condensation between acetone and isobutyraldehyde are explored. The experiment illustrates some of the trade-offs involved in green chemistry like the use of acetone in large…
