Various approaches to the standardization of pH meters are compared and the limitations of each are pointed out. (BB)

The American Public Health Association has instituted a Quality Assurance Analysis and Review (QUASAR) program to provide consultative services to laboratories.(BB)

This article describes how a gas chromatograph may be used to determine the amount of carbon dioxide in exhaled air. The experiment has been used as part of a demonstration exercise at a local science fair and proved of interest to all age groups. (Author/BB)

Unsafe academic chemistry departments are a result of a lack of incentive, ignorance of the hazards, historical perspective, and a lack of funds. A program implemented at Wright State University to overcome these obstacles is described. (BB)

This article discusses a cataloging and coding system especially designed for language lab courseware. (Author/NCR)

Explains what superheated liquids are and how they are prepared. (BB)

Principles, methods, and materials for a laboratory experiment in the generation of methane gas as an alternative energy source are described and illustrated by an industrial arts professor and student for students in power and energy. (MF)

Describes a seven piece modular optical hit which can be utilized to demonstrate different optical instruments and a method for observing interference fringes from the surface of a mirror. (SL)

Reviews eleven categories for controlling hazards in laboratories. (SL)

Describes a grading technique for a laboratory program, designed to apprise the student each week of his performance and relative standing with peers. (SLH)

Describes an experiment where equal parts of copper and aluminum are heated then cooled to show extremely large crystals. Suggestions are given for changing the orientation of crystals by varying cooling rates. Students are more receptive to concepts of microstructure after seeing this experiment. (DH)

Proposes use of two experiments to sample and analyze contaminents in the laboratory. Experiments focus on estimating hydrogen sulfide levels in the general chemistry laboratory during qualitative analysis and determining the concentration of organic vapors associated with organic chemistry laboratories. (JN)

Describes the construction and application of a device small enough to be worn on a worker's clothing that can monitor exposure to mercury. (MLH)
