Presents highlights from "The Technological Marketplace: Supply and Demand for Scientists and Engineers," a report which provides a synthesis of data found in 50 other reports. In addition, these data are analyzed and trends pointed out for such fields as chemistry, chemical engineering, and other science/engineering fields. (JN)

Provides abstracts of five papers presented at the Fourth Annual Microcomputers in Education Conference. Papers considered microcomputers in science laboratories, Apple II Plus/e computer-assisted instruction in chemistry, computer solutions for space mechanics concerns, computer applications to problem solving and hypothesis testing, and…

Presents and analyzes data on sources of research and development (R&D) funds; R&D spending by government agencies; how industry apportions its R&D outlays; spending by individual chemical companies; manpower in industrial R&D; sources/uses of academic R&D funds; largest spenders on R&D; and demographic trends. (JN)

Describes a demonstration in which gaseous ammonia and hydrochloric acid are used to illustrate rates of diffusion (Graham's Law). Simple equipment needed for the demonstration include a long tube, rubber stoppes, and cotton. Two related demonstrations are also explained. (DH)

Reviews background of atomic absorption spectrometry techniques. Discusses problems encountered and precautions to be taken in determining trace elements in the parts-per-billion concentration range and below. Concentrates on determining chromium in biological samples by graphite furnace atomic absorption. Considers other elements, matrices, and…

Describes a laboratory experiment which explores the effects of adding inert salts to electrolytic cells and demonstrates the difference between concentration and chemical activity. Examines chemical potentials as the driving force of reactions. Provides five examples of cell potential and concentration change. (JM)

Describes an experiment combining qualitative and quantitative information from hydrogen nuclear magnetic resonance spectra. Reviews theory, discusses the experimental approach, and provides sample results. (JM)

Provides a short history of chemistry education in the United States. Indicates that although the chemistry of the first half of the twentieth century was theoretical in nature, chemistry teaching today seems to be returning to the utilitarian focus of colonial chemistry. (JN)

The chemistry and chemical engineering department's experiences with an institution-wide research evaluation process is discussed, focusing on the departmental input into the process, the estimation of research activity and productivity, and the evaluation of the research's relevance to teaching, international research, and society. (MSE)

Presents excerpts of a survey on the instrument status in chemistry departments and the perceived needs of those departments for new instruments. Responses are based on data from 32 chemistry departments at major research institutions, 71 departments at smaller schools, and 13 chemical engineering departments. (JN)

Describes an innovative freshman chemistry program in which course sequences have been designed to accommodate students with strong or weak chemistry backgrounds or with no previous chemistry at all. Includes information on courses offered, instructional strategies, and laboratory examinations. (JN)

Describes graphical solutions of equations for stirred-tank reactors in series; data management software for producing and searching customized mass spectral libraries; least squares and chromatography programs; a low-cost data acquisition system for Apple microcomputers; nuclear magnetic resonance interpretation with graphics; chemical bonding…

Presents 23 experiments, activities, field projects and computer programs in the biological and physical sciences. Instructional procedures, experimental designs, materials, and background information are suggested. Topics include fluid mechanics, electricity, crystals, arthropods, limpets, acid neutralization, and software evaluation. (ML)

Discusses the growing awareness of potential toxicological effects of synthetic organic chemicals contaminating groundwater. Problems concerning pesticides, chlorination, epidemiologic studies, cancer, nephrotoxicity, and considerations of risk are addressed. Additional research in this area is advocated. (DH)

Describes the science program at Incarnate Word, a private Catholic girls' college preparatory school in San Antonio (Texas). Focuses on the chemistry curriculum and the instructional strategies/materials (such as learning activity packets) used in the curriculum. (JN)
