Analyzes the relationship between allied health students' (N=304) performance in general chemistry and the American Chemical Society's Toledo Exam (Form 1974), mathematical Scholastic Aptitude Test (SAT) scores, and high school chemistry grade. Also discusses use of findings to identify students who had a high risk of receiving low grades. (JN)

Describes the nature, implementation, evaluation, and future plans of an international cooperative work experience program (called the ABC model) in which undergraduate students combine travel with employment in industrial research-oriented projects. The program involves universities in Australia, Great Britain, and Canada (the letters ABC…

Describes an interdisciplinary chemistry course at the New Jersey Institute of Technology (NJIT) in which at least one quarter of the time is devoted to materials science. Includes information on course content, laboratory work, and assessment of student performance on chemistry and materials science topics. (JN)

The environmental chemistry program at Vassar College consists of undergraduate- and graduate-level coursework in environmental chemistry, a research program, and a program of involvement with environmental problems in the Mid-Hudson area. Various aspects of this interdisciplinary, integrated program are discussed. (JN)

Discusses (1) instructional uses of VisiCalc; (2) use of a spreadsheet to calculate the activity coefficients of lead in amalgams from measurements of the potentials of cells without liquid junction; and (3) the computerized solution (analogous to a titration) of simultaneous equations for determining equilibrium pH of a raindrop. (JN)

Describes a two-term course in electronic instrumentation for chemistry and physics students. The first term focuses on analog circuits and the measurement of voltage, current, and impendance. The second-term course focuses on digital pulses/logic, microcomputer organization, and assembly language programing and interfacing to experiments. (JN)

Smaller amounts of materials are used in organic chemistry experiments as a means of improving air quality in the laboratory. Presents a preliminary study of the emissions from selected processes and the mixing of these emissions within the laboratory atmosphere. (JN)

Smaller amounts of materials are used in organic chemistry experiments as a means of improving air quality in the laboratory. Outlines benefits from this approach and describes two representative experiments in detail. These experiments are the Cannizzaro reaction and preparation of an aromatic nitrile. (JN)

Two demonstrations are described. The first (useful as an introduction to kinetics) shows how the rate of a reaction is fast at first and then gradually decreases to zero when one reactant has been used up. The second is a gas density demonstration using 1,1,2-trichloro-1,2,2-trifluoro ethane. (JN)

Shows how a standard slide projector can be adapted for use as an effective spectroscope. Also describes three experiments using the modified slide projector. (JN)

To have students develop observational skills and acquire an excitement about chemistry, stereoscopic dissecting microscopes are used to observe the physical characteristics and chemical reactions of various substances. Several of these reactions (including dissolving potassium permanganate in deionized water and reactions between copper metal and…

Discusses three topics that have been improperly applied to the acidic precipitation issue. They are: (1) use of the pH scale; (2) acidity; and (3) solution equilibria of strong and weak acids. Implications for instruction are considered. (JN)

Describes a freshman chemistry experiment in which students separate and identify commonly used drugs by thin-layer chromatography. Materials needed, procedures used, and typical results obtained are included. (JN)

Procedures are provided for a flame emission experiment which covers five areas in a single laboratory exercise. These areas are: (1) the flame emission technique; (2) calibration plots; (3) interferences; (4) indirect flame emission analysis; and (5) techniques of removing interferences. Typical results obtained are discussed. (JN)

Describes a low-cost ($120) device which eliminates plasma lines in Raman spectra. The device consists of two prisms and two mirrors which are held in a symmetrical relationship to one another so that a particular position will allow only one wavelength to pass through on a given axis. (JN)
