Describes a simple thermodynamics experiment recommended for use in beginning chemical engineering laboratory courses. Outlines the theory behind the experiment, which determines the specific heat of a liquid. Discusses the construction, operation, and maintenance of the apparatus involved, along with the experimental procedure. (TW)

Reports on a study which investigated the effects of having students analyze circuits in the laboratory compared with troubleshooting from homework problems. Results indicated that laboratory experiences provide a richer learning experience than lecture and homework alone. (TW)

Described is an experiment designed to provide an experimental basis for a unifying point of view (utilizing theoretical framework and chemistry laboratory experiments) for physical chemistry students. Three experiments are described: phase equilibrium, chemical equilibrium, and a test of the third law of thermodynamics. (Author/DS)

Discusses the hazards of nitric acid and other nitrates, especially ammonium nitrate in the high school laboratory. Provides many historical accounts on the dangers of nitrates. (MVL)

Describes a method for making a simple, inexpensive apparatus which can be used to determine Planck's constant. Provides illustrations of a circuit diagram using one or more light-emitting diodes and a BASIC computer program for simplifying calculations. (RT)

Provides a point of view that the organic lab is a good place for the student to use and learn problem solving skills while performing the cookbook experiments. Notes that an equilibrium between the theoretical and practical aspects of organic chemistry should be established. (MVL)

In an attempt to generate student enthusiasm on the subject of genetics, the author developed a Punnett square activity centered on the genetics of corn snakes to teach students about Mendelism and genetic diversity. As they began the activity, however, some unexpected twists occurred that allowed for investigation into corn snake anatomy and…

This document is written to encourage college faculty to use a student-centered, activity-related, approach to science instruction. Suggestions are provided for methods that can be used by faculty and administrators to develop alternatives to lecturing. The major sections of this document include the following: (1) Is There an Alternative to…

Reports on the session at the New England Association of Chemistry Teachers meeting on chemistry laboratories in March 1987. Speakers included Leonard K. Nash and Audrey Champagne on values and goals; Howard Ende on regulation; Stanley Smith and Jerry Bell on the uses of computers; and Miles Pickering on the human dimension. (CW)

Describes a molar volume-molar mass experiment for use in general chemistry laboratories. Gives background technical information, procedures for the titration of aqueous hydrogen peroxide with standard potassium permanganate and catalytic decomposition of hydrogen peroxide to produce oxygen, and a discussion of the results obtained in three…

Expresses concern over recent actions by coalitions of neighborhood activists and animal rightists in the San Francisco area that are seeking to block new biology laboratories. Argues that costly delays and disurption of research could result. (TW)

This description of microcomputer-based laboratories (MBL) for science focuses on experiments with a motion detector by non-science majors at Tufts University. Exercises had been used previously with sixth grade middle school students, indicting the effectiveness of MBL for students with a wide range of abilities. (Author/LRW)

This document presents a collection of articles selected from the Journal of College Science Teaching. The selected articles represent how college science teaching should be practiced and include modifications in classrooms and laboratories to allow for the development of inquiry skills. Articles include: (1) "What Should Students Learn about the…

The use of microcomputers in the undergraduate chemistry laboratory is presented. Examples are included which can be implemented in the PET 2001. (SA)

This paper, presented at the conference on the role of the laboratory in physics education, which was held in Oxford, England in July 1978, describes the role of the laboratory in school and university physics in Honduras. (HM)
