Compares the similar mathematical problems of molecular vibrational calculations (at any intermediate level of sophistication) and molecular orbital calculations (at the Huckel level). Discusses how the generalizations of Huckel treatment of molecular orbitals apply to vibrational theory. (TW)

Discusses the use of specific reactions of metabolic pathways to make measurements in the laboratory. Describes an adaptation of an experiment used in undergraduate biochemistry laboratories involving the induction of an enzyme in E. coli, as well as its partial purification and characterization. (TW)

Since 1979, high school teachers from urban and rural areas of northeastern Ohio have brought their students to visit the College of Wooster Chemistry Department to learn about instruments. Rationale for the program and program activities are described. (JN)

Provides data on employment by sex, degree, and minority status. Compares men's and women's salaries in private industry, academia, and government. Provides breakdown for industrial employment by work function and work specialty, and compares industries. (JM)

Presents a laboratory experiment which determines critical temperature and density of carbon dioxide. Discusses critical point and provides equations to estimate liquid volume fraction. Analyzes experimental results in terms of variables. (JM)

Presents the exploded structure method for determination of oxidation states in covalently bound atoms. The three step method is illustrated with four examples and compared to popular textbook presentations. (JM)

Presents a case study analysis which attempts to illuminate the difference between knowledge accumulation and ability to deal with problem solving in stoichiometry. Competence is presented as ability to properly represent, solve, and verify solutions. Discusses rule or algorithm based vs. heuristic based problem solving. (JM)

Cites advances in x-ray diffraction, nuclear magnetic resonance, computer modeling, and display to guide the design and analysis of protein structures. Reviews recent advances in knowledge, synthesis techniques, and theory of proteins. (JM)

Describes the Dominican Study of Environmental Adaptation of Marine Organisms ("D.SEA"). Includes information organization and funding, purpose and goals, preliminary experiences with the program, and comments by the 14 students who have been working in the program. (JN)

Discusses three trends in computer-oriented chemistry instruction: (1) availability of interfaces to integrate computers with experiments; (2) impact of the development of higher resolution graphics and greater memory capacity; and (3) role of videodisc technology on computer assisted instruction. Includes program listings for auto-titration and…

A gas chromatography (GC) mass spectroscopy (MS) system recently developed by Hewlett-Packard (HP-5987 GC/MS/Data System) is described, illustrating the technological advances that have been achieved with the system. Examples of the data processing and output process are provided to demonstrate the capabilities and application of the system to…

Outlines a cooperative effort in Iowa to eliminate dangerous or unwanted chemicals from school science storerooms. Also reviews the Council of State Science Supervisor's safety program and discusses how to prevent cuts and punctures from jagged glass tubing. (JN)

Reviews historical and current patterns in chemistry instruction, listing influences on chemistry curriculum development and identifying change elements in science education. Enumerates major advances in the nature of chemistry and the subsequent impact on school chemistry. (ML)

Invites colleagues in the "hard" sciences to embrace writing, reading, and thinking across the curriculum, and describes the use of "project" and "concept" composition assignments to that end in an organic chemistry course. (HTH)

Discusses how "live" experiments were combined with media packages and recorded lectures to allow coverage of more material and foster greater student/teacher interactions. Notes were distributed at the beginning of the semester which allow students to record experimental data from class demonstrations. Problems and suggestions for course…
