Describes a physical chemistry experiment that introduces undergraduate students to the entities of polyelectrolytes. (CS)

Describes the impact on chemistry laboratories and teachers in the United Kingdom of the Packaging and Labelling of Dangerous Substances Regulations 1978. These regulations require suppliers to label containers in particular ways. (HM)

Presents an improved technique for synthesizing acetanilide from nitrobenzene by reducing nitrobenzene with iron powder and hydrochloric acid. This experiment has been used successfully with 2,000 students during two semesters. (Author/SA)

Discusses safety in school laboratories and school lab accidents in Britain and suggests ways of reducing potential hazards of school science. (HM)

Presented are the results of a survey conducted to identify occupational health efforts in university chemistry laboratories. (HM)

The new chemistry facility at the University of Akron, heralded as one of the safest chemistry buildings ever constructed, is described. Topics discussed include: preliminary planning, general building design, design of specific areas, and safety training for personnel. (BT)

A modification of the Ames test for detecting carcinogens and mutagens using a strain of bacteria is described. A suggestion is given for checking the correctness of procedures by using particular hair dyes which have been shown to be mutogenic. (Author/SA)

Using hypothetical lawsuits as examples, the more common rules of law which define the acceptable conduct of a physics teacher in the classroom, laboratory, and general school area are examined. (BT)

Discusses the impact of using laboratory exercises and queries on developing student sensitivity to bioethical issues. Examples of these questions and the responses of students of an introductory life science course at Worcester Polytechnic Institute, Worcester, Massachusetts are presented. (HM)

Describes techniques for making laboratory glassware from discarded bottles, fluorescent tubes, and light bulbs. All materials needed are constructed from commonly available household items. (SL)

Faculty members at Temple University listed proposed student and faculty functions desirable for a new language laboratory; this article describes the Media Learning Center which resulted. The Center contains an audiotape theater, slide and filmstrip theater, videotape and multi-media theaters and resources library. Audiovisual equipment in each…

Reports on a study that assesses the effects of the application of visual information-processing theory to the design of a laboratory manual for chemistry. Focuses on the effects on content learning, practical skill mastery, and attitudes of university students enrolled in a general chemistry course. Contains 41 references. (DDR)

Discusses modular technology labs and their effect on education. Describes modules offered by CHEC Systems (Consumer and Home Economics); Paxton/Patterson; Marcraft; Lab-Volt; Synergistic Systems/Pitsco; as well as some that were created from the ground up by teachers. (JOW)

Provides descriptions of a range of resources and methods that can be used to produce metals such as titanium, vanadium, chromium, manganese, iron, and molybdenum. Details on equipment and safety precautions are also outlined. (DDR)

Introduces an alternative method to determine the mechanics of a moving object that uses computer vision algorithms with a charge-coupled device (CCD) camera as a recording device. Presents two experiments, pendulum motion and terminal velocity, to compare results of the alternative and conventional methods. (YDS)
