Describes the overall design of the physical sciences building, the numerous and flexible facilities it includes and looks at specific teaching and research areas. Reflects favorably on the practical design and success in using the facilities. (GA)

Describes a simple method, the Edser-Butler methods, for calibrating the Fabry-Pevot fringes seen in the focal plane of a spectrograph. (GA)

Describes some of the advantages of having the science teacher develop, use, maintain, and troubleshoot the new instructional materials. (GA)

Describes two tests, T-4 and T-3, for hypothyroid based on the binding of the hormones by proteins. The tests were performed in courses for physicians, clinical chemists, laboratory technicians, and undergraduate science students by the individuals involved and on their own sera. These tests are commercially available in kit form. (GA)

Describes how to determine heats of adsorption by means of gas-solid chromatography. Explains the measureable variables involved, the relationships among them, and the graphs to be drawn. (GA)

Describes a machine which demonstrates the statistical bases of chemical equilibrium, and in doing so conveys insight into the connections among statistical mechanics, quantum mechanics, Maxwell Boltzmann statistics, statistical thermodynamics, and transition state theory. (GA)

Investigates effects of children's learning center experience on academic achievement, self-concept, attitudes toward peers, educational institutions, and authority. Results indicate that elementary school pupils who had used the centers scored better on post-tests than those who had not used the centers. Discusses positive effects of learning…

Proposes an alternative to the classical minimum-deviation method for determining the refractive index of a prism. This new "fixed angle of incidence method" may find applications in research. (Author/GA)

Presents a simplified theoretical analysis of the variation of quantum yield with photon energy in the photoelectric experiment. Describes a way to amplify the experiment and make it more instructive to advanced students through the measurement of quantum yield of a photo cell. (GA)

Describes an experiment which studies the motion of an irregular Lucite glider on an air table and demonstrates the dynamic properties of the center of mass. (Author/GA)

Describes an experiment which utilizes the technique of double-exposure holographic interferometry to demonstrate electromagnetic wave radiation-pressure effects on an illuminated object. (Author/GA)

Describes an experiment, in solid-state physics, for measuring the Shubnikov-de Haas oscillations in indium antimonide. It also provides an introduction to low-temperature techniques and to cryomagnetic systems. (Author/GA)

This experiment is designed specifically for students with little knowledge of radical reactions and provides an introduction to the gas-phase chemistry of radicals. Experimental planning based on the student's own observation is an important component of the experiment. (Author/MA)

Reported here are brief descriptions of a common grading and scaling formula for large multi-section courses, an ion exchange amino acid separation and thin layer chromatography identification experiment, a conservation of energy demonstration, a catalyst for synthesizing esters from fatty aids, and an inexpensive method for preparing platinum…

The construction of an operational amplifier for use in a chemical instrumentation course is described. (CP)
