Presented is a photoelectric colorimeter which can be assembled by the student. Reports that it can do many of the same analyses as the SPEC 20 but at a greatly reduced cost using older technology. Presents several experiments to use with the colorimeter. (MVL)

Explains the use of the microcomputer as a multipurpose analytical instrument which frees students from the mechanics of science and allows for more active learning involvement. Provides the typical data acquisition configuration, advantages, disadvantages, and a brief summary. (RT)

Recounts a high school chemistry lab explosion while distilling alcohols. Proposes peroxide formation in older samples of alcohols as the cause. Lists commonly found laboratory alcohols and their peroxide concentrations. Discusses methodology for both detecting and removing peroxides. (MVL)

Discusses a method for teaching time pulsed NMR principals that are as simple and pictorial as possible. Uses xyz coordinate figures and presents theoretical explanations using a Fourier transformation spectrum. Assumes no previous knowledge of quantum mechanics for students. Usable for undergraduates. (MVL)

Describes a new BS degree in secondary science/mathematics teaching being offered at Florida State University. Notes that the science concentration is either chemistry-physics or chemistry-biology. Indicates approximately 40 semester hours split between the science subjects are required. Notes that both a prospective and inservice track are…

Reports that the space agency provides universities with resources to invigorate and increase the effectiveness of space-related engineering research and education. Lists selected University Space Engineering Research Centers with a description of their concept, a program schedule, information and address for submitting future proposals for a…

Outlines one university's process of planning and preparing a successful proposal for a space research center which focused on a broad, cross-disciplinary study. States that as a result of the center, four new graduate courses were offered and a higher than average enrollment was attracted to the school. (RT)

Describes an engineering course for graduate study in process control. Lists four major topics: interaction analysis, multiloop controller design, decoupling, and multivariable control strategies. Suggests a course outline and gives information about each topic. (MVL)

Describes the use of "CACHE IBM PC Lessons for Courses Other than Design and Control" as open-ended design oriented problems. Presents graphics from some of the software and discusses high-resolution graphics workstations. Concludes that computing tools are in line with design and control practice in chemical engineering. (MVL)

Presents data from studies conducted on student self-discipline and attitude toward biology. Suggests reasons for the difficulties non-biology majors experience in college biology classes. Proposes several ways that biology instructors can help their students improve their performance and attitudes in non-major biology classes. (CW)

Describes an activity that combines manual and computer simulation of a population undergoing selection using three alternative genetic models. Discusses procedures used, model and how the computer simulation works. Stresses the advantage of using the student involvement of the manual exercise in combination with the speed of the computer…

Evaluates and compares common eyewash stations currently being used in laboratories. Discusses types available, installation, water supply needs, and maintenance. Lists current OSHA eyewash station standards. (ML)

Reexamines the electronic structure of water considering divergent views. Discusses several aspects of molecular orbital theory using spectroscopic molecular orbitals and localized molecular orbitals. Gives examples for determining lowest energy spectroscopic orbitals. (ML)

Describes why specific forms of orbitals used to interpret spectroscopy involving electronic transitions may not say much about the electronic structure of molecules. Discusses several theoretical approaches to explain the anomoly. Determines that the Lewis electron-pair model for molecules is a good predictor of spectroscopic results. (ML)

Considers two types of laser applications in kinetics. Explores short laser pulses to prepare a reactant in a known state and a continuous laser as a probe to monitor specific species in a reaction. Describes how lasers work and provides several examples of kinetic reactions. (ML)
