Reports on a study in which two spatial tests were given to science and engineering majors and to students in nursing and agriculture at Purdue University (Indiana). Scores from the tests consistently contributed a small but significant amount of success on measures of performance in chemistry. (TW)

Explores several of the issues raised by current and likely future scientific advances which may challenge the United States Constitution. Reports on the results of the "Science, Technology, and the Constitution in an Information Age" project. Focuses on the chemically related technological advancements that may challenge this nation's…

Presents three specific examples of chemical engineering problems which can be interactively solved on personal computers with commercially available software. Illustrates the potential impact of interactive problem solving on chemical engineering. Discusses how this has been accomplished at Ben Gurion University (Israel) and the University of…

Describes an experiment involving data acquisition by a computer, digital signal transmission from the computer to a digital logic circuit and signal interpretation by this circuit. The system is being used at the Illinois Institute of Technology. Discusses the fundamental concepts involved. Demonstrates the alarm experiment as it is used in…

Discusses the loss of precision that normally results in solving equilibrium problems, particularly as presented through the use of quadratic formulas in most introductory college chemistry textbooks. Provides examples of demonstrations. (TW)

Describes a successful two-week summer program for children in grades four through six of above average ability. Discusses the purposes and syllabus for the program. Provides a summary of a typical daily agenda and discusses events that occurred during the two-week period. (CW)

Discusses demand for chemists and chemical engineers in 1986 and the first half of 1987. Examines the employment outlook by degree, time of year, industry, and institution. Makes predictions for the next year. Examines the starting salaries for B.S., M.S., and Ph.D. chemists. Discusses inequities by degree, experience, and gender. (CW)

Discusses the state of biochemistry education in the United Kingdom. Gives an overview of the current educational system. Lists the problems of the school children, the school teachers, and the university teachers and emphasizes problems in the school syllabi. Suggests solutions to these problems. (CW)

Illustrates the scope of experimental investigations for biochemistry education in high school biology and chemistry courses. Gives a brief overview of biochemistry experiments with proteins, enzymes, carbohydrates, lipids, nucleic acids, vitamins, metabolism, electron transport, and photosynthesis including materials, procedures, and outcomes.…

Reviews a National Science Foundation funded workshop ("Investigations in the Natural Sciences") for science teachers on how to use laboratory centered materials developed by the Science Education Center at the University of Oklahoma. Presents the results of a survey of the participants. Highlights the program's strengths. (CW)

Discusses the need for safety programs in small colleges/universities and secondary schools, addressing objectives of such programs and major program components. Sample forms are included (hazardous materials log sheet, laboratory class safety checklist, laboratory room safety checklist, injury accident report, noninjury accident report, and room…

Differentiates the tricarboxylic acid (TCA) cycle (or Krebs cycle) from glycolysis, and describes the bridge between the two as being the conversion of pyruvate into acetyl coenzyme A. Discusses the eight steps in the TCA cycle, the results of isotopic labeling experiments, and the net effects of the TCA cycle. (TW)

Describes a laboratory experiment in which benzene fluorescence is quenched by bis(acetylacetonato) copper(II). Discusses how this experiment can demonstrate a special technique used in the field of photochemistry. Provides an outline of the experimental procedure and discusses its results. (TW)

Discusses the concepts of relativity, mass, and energy, and the relationships between them. Argues that mass conservation inevitably follows from energy conservation. Proposes a scheme for introducing the laws relating to these concepts in general chemistry courses. (TW)

Describes a method of flow injection analysis intended for calculation of complex-formation and redox reaction stoichiometries based on a closed-loop configuration. The technique is suitable for use in undergraduate laboratories. Information is provided for equipment, materials, procedures, and sample results. (JM)
