Discusses some aspects of one-dimensional magnetism, the motivating factors that influenced the increase in the literature dealing with it, and the progress that has been achieved in this field. (GA)

Loyola Academy, a Jesuit high school located in Wilmette, Illinois, offers basic chemistry, chemistry I, and advanced placement chemistry. (BB)

Discusses the role of the chemical industry since the 1930's and reviews its possible role relating to pending world energy problems. (SL)

Presents excerpts from the scientific writings of Boyle and Newton to demonstrate their use of metaphysical models. (CP)

Discusses the solubility characteristics of bromine salts. (CP)

Explains how to construct a three dimensional model for stereographic projection. It will be suitable for presenting the symmetry of crystal systems, and will help physics students understand the nature of crystallography. (GA)

Describes how the color of an object is related to its chemical structure. (CP)

Data reveal that the absorption spectra of alkali metals can be analyzed using a modified laboratory procedure. ( CP)

Discusses the operation of a computer simulation of the formation of ozone in the atmosphere. Educational uses of the computer program and availability of the product are described. (CP)

The operation of teaching associates (TA's) in reference to McGregor's ideas concerning Theory X and Theory Y Management is discussed. (CP)

Tested demonstrations on (a) color development through the formation of subtractive primary dyes and (b) fluidity of gases are presented. (CP)

Calculates energy expenditures for the activities of running and bicycling and discusses the heat dissipative perspiration system of the human body. (CP)

Provides a description of the development, properties, and operation of laser beams. (CP)

A survey of the place of practical work in sixth-form biology teaching is described. Changes in the declared aims of teachers since 1962 are examined and discussed in the light of recent curricular changes. Some comparisons with similar samples of physics and chemistry teachers are made. (Author/MA)

Ethylene hydrogenation on a platinum catalyst, electrolytically applied to a tube wall, is a good system for the study of the interactions between diffusion and surface reaction in heterogeneous catalysis. Theoretical background, apparatus, procedure, and student performance of this experiment are discussed. (BB)
