Describes a three-part experiment designed to introduce cyclic voltammetry to graduate/undergraduate students. Part 1 demonstrates formal reduction potential, redox electron transfer, diffusion coefficient, and electrochemical reversibility. Part 2 investigates electrochemical behavior of acetaminophen. Part 3 examines such experimental variables…

Lists: (1) educational uses of microcomputers; (2) goals of a microcomputer selection committee; and (3) goals to be achieved by students owning microcomputers. Discusses progress made by the selection committee, faculty development in computer literacy, current preparations being made for the arrival of the microcomputers, and computer uses in…

Discusses the importance of teaching the Bohr atom at both freshman and advanced levels. Focuses on the development of Bohr's ideas, derivation of the energies of the stationary states, and the Bohr atom in the chemistry curriculum. (SK)

A 10-12 class session unit, based on a series of worksheets (available from the author), is described, including objectives, major topics covered, and instructional and study strategies. A brief pilot evaluation indicates positive student and teacher attitudes toward the unit. (SK)

Safety procedures used by Department of Chemistry at the University of Akron are discussed. These include policy that no chemicals are stored in the teaching laboratories. Instead, dispensing stockrooms are used to service the laboratories. Other aspects discussed include ventilation procedures and development of microprocessor use in stockrooms.…

Describes a lecture demonstration of a solid state phase transition using a thermodynamic material which changes state at room temperature. Also describes a demonstration on kinetics using a "Big Bang" (trade mark) calcium carbide cannon. Indicates that the cannon is safe to use. (JN)

Describes the development, content, and implementation of a two-credit graduate course for teachers at the University of Wisconsin at Stevens Point in the use of microcomputers for teaching high school chemistry. (JJD)

Describes fluorescence demonstrations related to several aspects of molecular theory and quantitized energy levels. Demonstrations use fluorescent chemical solutions having luminescence properties spanning the visible spectrum. Also describes a demonstration of spontaneous combustion of familiar substances in chlorine. (JN)

Undergraduate-level student research benefits both faculty and students, but the scarcity of public/private funding and loss of National Science Foundation (NSF) support are clouding the outlook. (Author/JN)

Summarizes papers and minipapers on honors and advanced placement (AP) chemistry courses presented at the Seventh Biennial Conference on Chemical Education (Stillwater, Oklahoma 1982). Advantages/disadvantages of AP chemistry, high school/college courses, and grouping all chemistry students in one class were among the topics discussed. (JN)

Highlights seminar which addressed education of the nonmajor. Following brief comments on plan/execution of the seminar program and Japanese system of education, 19 recommendations are outlined and summarized. Recommendations focus on various aspects of courses, curricula, instructional strategies, and other factors related to nonmajors in the…

Selected aspects of a self-paced chemistry program are described. These include student selection, supervision requirements, and grading indicating that student selection is the key to a successful program. Also points out that quality/quantity of learning (determined by testing) is comparable to traditional lecture courses. (Author/JN)

Describes an inexpensive tensiometer, a balance consisting of a plastic drinking straw as the crossarm, a needle as a pivot, and wire loop counter balance to assure proper balance. The instrument permits the quantitative demonstration of interfacial tension and effects of various agents that modify it. (Author/JN)

Describes a low-cost, high-voltage, two-terminal, constant-current source for student use in electrophoresis experiments (includes circuit diagram) and a simple device for the continuous registering of gas flows. Also lists seven cost-saving tips for chemical reagent, including use decorative stones (purchased from nursery stores) in place of…

Describes an industrial and engineering chemistry course organized on a case-study approach. The course theme is process conceptualization (creation of chemical processing routes). Flowcharts/flowcharting, quantitative aspects of industrial chemistry, teaching the course, use of patents, student evaluation, and useful references are discussed. A…
