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)

Methods for organizing and storing chemicals in teaching laboratories and preparation rooms are given, emphasizing storing and handling of flammable liquids. Two appendices are given: (1) flash points and autoignition temperatures of common flammable liquids; (2) content of a kit, with instructions, for cleaning up spills of flammable liquids. (JN)

Describes a new apparatus for Drosophila habitats which has the advantage of leaving pupae and adult flies undisturbed while being able to renew or move the media and larvae at will. (CS)

The laboratory curriculum of an introductory physical geology course which emphasizes a peer-learning approach is discussed. (Author/SA)

Suggestions are given for safety precautions in the secondary school science laboratory. Emphasis is placed on fire safety and identification of particularly hazardous situations. (SA)

Describes the Crime Lab Project, which takes an economical, hands-on, interdisciplinary approach to studying the career of forensics in the middle or high school classroom. Includes step-by-step student requirements for the investigative procedure, a sample evidence request form, and an assessment rubric. (KHR)

Describes the Desert Willow Library and Classroom Building, Mesquite Student Services and Administration Building, Palo Verde Science Laboratories and Classroom Building, and Ironwood Central Plant of the title college, including educational context and design goals. Includes a general description; information on the architect, construction team,…

To avoid a tedious task for recording temperature, a computer was used for calculating the heat of crystallization for the compound sodium thiosulfate. Described are the computer-interfacing procedures. Provides pictures of laboratory equipment and typical graphs from experiments. (YP)

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)

Presents a programed method that inventories and classifies hazards. 8iscusses the following topics: (1) student and hazard source, (2) elimination of the source, (3) adaptation of the source, (4) isolation of the source, (5) adjustment of the surroundings, (6) isolation of man, and (7) personal protective equipment. (MVL)

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)

Describes a method of teaching geology and scientific writing to nonscience students that combines active integration of lecture, reading, and laboratory materials with field observations into a writing assignment on a real scientific problem. The writing assignment is completed in stages: a prospectus, a detailed report outline, a bibliography, a…

Describes the Alabama Science in Motion Program (ASIM) which provides hands-on science laboratories to high school students. Discusses the benefits of the program for host teachers and its impact on students and preservice teachers. (YDS)

Internet learning opportunities via the National Science Foundation-supported New Jersey Networking Infrastructure in Education project are described. Their data-centered approach to science and math skills instruction is illustrated by two examples from each of the three styles of activities: (1) collaboration; (2) using public domain databases;…
