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)

Examines the major factors that influence the education of students and the continuing education of faculty in the earth sciences. Identifies and discusses the influences external to the field, those within the university structure, and factors within the science. Also includes earth science enrollment and employment data. (ML)

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)

Explains the principles of the Doppler ultrasound technique and reviews its potential applications to the teaching of cardiovascular physiology. Identifies the instrumentation needed for this technique; provides examples and illustrations of the waveforms from the ultrasound blood velocimeter. (ML)

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)

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)

Describes three demonstrations/activities that involve forces: (1) a canoe-like boat made from copper window screen; (2) magnetic forces with a paper clip and ceramic magnetic; and (3) an "icemobile" machine that cuts ice cubes without an obvious source of energy. (DH)

The Center for the Analysis of Marine Systems (CAMS) was created as an interdisciplinary "think tank" to meet needs of modern oceanography. The international research center's focus and success rests on theory, observation, and computer modeling. Projects involving lava flow and year-to-year variations in abundance of fish are described. (DH)

Lists books, pamphlets, and articles of interest to teachers addressing "science, technology, and society" in the curriculum. This extensive bibliography includes international sources as well as those from public and private groups. (DH)

Evaluates the Measurement Module (TEL-Atomic, Incorporated), a real time data capture and display instrument which (according to the manufacturer) was designed primarily for use in demonstrations. Includes comments on the module's specifications and features, software, documentation, and student laboratory use. The module is compatible with Apple…
