Fourteen papers presented at the Seventh Biennial Conference on Chemical Education (Stillwater, Oklahoma 1982) are summarized. Papers focused on secondary/college chemistry courses, programs, instructional strategies, and projects emphasizing the relationship of chemistry to "real world" problems and issues. (JN)

Forty-five "poster session" papers presented at the Seventh Biennial Conference on Chemical Education (Stillwater, Oklahoma 1982) are highlighted. These papers focused on computers in chemistry and chemical education (emphasizing programs) and on instructional innovations (including courses, teaching methods, testing, experiments, and others). (JN)

Describes a two-semester laboratory program designed to motivate students. The program consists of computer-oriented modules and discovery approach laboratory exercises. Students complete similar computer/laboratory material during the first semester but elect one of three tracks during the second semester (computer, every-day life, and…

Describes three methods for offering practical work for external science courses: residential sessions on campus, local centers, and use of home laboratory kits. The advantages and disadvantages of each are discussed and examples of each in operation are given. A 21-item bibliography is provided. (EAO)

Microcomputer-based instrumentation packages enable computers to collect continuous analog data, convert data to digital form for processing, and display results on monitor. Discusses classroom advantages of these packages, describes one package for teaching harmonic motion, and provides a list of currently available packages (including vendor and…

A shoe box is converted into a model home to demonstrate the energy efficiency of various insulation measures. Included are instructions for constructing the model home from a shoe box, insulating the shoe box, several activities involving different insulation measures, extensions of the experiment, and post-lab discussion topics. (DS)

Outlines a variety of laboratory procedures, demonstrations, and classroom materials including a three dimensional, moveable cardboard model of the rib cage and diaphragm; a polyphenal oxidase experiment; ringing experiment using Impatiens; enzyme rummy game; and leaf impressions. (DS)

Discusses procedures, theoretical considerations, and results of an experiment involving the preparation of a tetrahedral nickel(II) complex and its transformation into an octahedral species. Suggests that fundamental aspects of coordination chemistry can be demonstrated by simple experiments performed in introductory level courses. (Author/JN)

Describes a student kinetic experiment involving second order kinetics as well as displaying photochromism using a wide variety of techniques from both physical and organic chemistry. Describes measurement of (1) the rate of the recombination reaction; (2) the extinction coefficient; and (3) the ESR spectrometer signal. (Author/JN)

Provides explanations of 15 experiments, laboratory activities, demonstrations, and lessons for use in instruction. Includes information on Daphnia, wild garlic, crystals, gas chromatographs, bleaches, alcohols, reactivity series, chemistry formula, electronic keyboards and waveforms, interference and diffraction gravity, Moire fringe patterns,…

Provides a first experiment for college chemistry that provides insights into scientific procedures without presupposing any detailed knowledge of chemistry on the part of the student. Requires the student to measure successive masses and volumes and use these values to determine the density from the slope of the graph. (MVL)

Describes a laboratory experiment to teach the principles of air sampling, gamma ray spectroscopy, nuclear decay, and radioactive equilibrium. Analyzes radon by carbon adsorption and gamma ray counting. Provides methodology and rate of decay equations. (MVL)

States that if photochemical reactions can be followed spectrophotometrically, reactivities can be estimated by evaluating data from only one curve. Studies such a system using computerized evaluation and simulation. Uses chlorocuprate(II) complexes in acetonitrile solutions for the model systems. (MVL)

Concentrates on the semiempirical methods MINDO/3, MNDO, and AMI available in the program AMPAC from the Quantum Chemistry Program Exchange at Indiana University. Uses charged ions in the teaching of computational chemistry. Finds that semiempirical methods are accurate enough for the general use of the bench chemist. (MVL)

Presents relevant statistics accumulated in a fall organic laboratory course. Discusses laboratory equipment setup to lower the amount of waste. Notes decreased solid wastes were produced compared to the previous semester. (MVL)
