Focuses on a recent approach to chirality that seeks to call attention to the fact that current usage of this term is often inconsistent with its proper relationship to molecular structure. (TW)

Illustrates the 18 steps to the development of a model of a coordination polyhedron that represents the cubic closest-packed structure. Uses a sealed, empty envelope in developing the model in teaching about stereochemistry. (TW)

Discusses combustion by suggesting several experiments and demonstrations using matches. Integrates quotes from famous scientists about the various phenomenon regarding combustion. (TW)

Discusses the establishment of a high school chemistry instrumentation center designed to retrain teachers, improve precollege preparation of high school chemistry students, and to make simple chemical instruments at a minimal cost. (TW)

Describes two demonstrations suitable for chemistry instruction. One involves fractal structures obtained by electrodeposition of silver at an air-water interface and the other deals with molecular weights and music. (TW)

Highlights aspects of safety that are unfamiliar to most laypersons and to many chemists as well. Presents findings that may lend themselves to presentation in chemistry classes. Details flammability tests, vapor space hazards, and the special case of gasoline containers. Provides experimental data relating vent area and internal pressure. (CW)

Reviews three computer software packages for chemistry education including "Osmosis and Diffusion" and "E.M.E. Titration Lab" for Apple II and "Simplex-V: An Interactive Computer Program for Experimental Optimization" for IBM PC. Summary ratings include ease of use, content, pedagogic value, student reaction, and cost. (CW)

Editorially reviews the history of reform in science education from the 1920s to 1983. Highlights agreement among the various reports. Specifies the role of chemistry education in science reform. Announces a new book from the National Research Council, "Opportunities in Chemistry, Today and Tomorrow." (CW)

Provides an overview based on personal experiences, recollections, viewpoints and anecdotal records. Discusses the general philosophy of education in the Soviet Union, the selection of students, graduate study and the chemistry curriculum. Compares and contrasts the educational systems of the Soviet Union and the United States. (CW)

Presents coulombic models representing the particles of a system by point charges interacting through Coulomb's law to explain coulombic lattice potential. Uses rubidium manganese trifluoride as an example of cubic perovskite structure. Discusses the effects on cluster properties. (CW)

Proposes the use of a relative atomic mass (RAM) scale in which hydrogen is assigned a value from one as a teaching aid for better understanding the concept of RAM. Helps to clarify the ideas and concepts about this topic. (CW)

Discusses the significance of periodicity and covalent atomic radius among the elements. Describes contraction across the row, expansion down the group, irregularities in the buildup of the periodic table and periodicities of physiochemical properties. (CW)

Describes five computer software packages; four for MS-DOS Systems and one for Apple II. Included are SPEC20, an interactive simulation of a Bausch and Lomb Spectronic-20; a database for laboratory chemicals and programs for visualizing Boltzmann-like distributions, orbital plot for the hydrogen atom and molecular orbital theory. (CW)

Gives the background history of the simultaneous discovery of acid-base relationships by Johannes Bronsted and Thomas Lowry. Provides a brief biographical sketch of each. Discusses their concept of acids and bases in some detail. (CW)

Describes the underlying pattern that, once seen, will allow students to describe the shape of any hydrogen orbital. Involves the exponential form of the orbitals. Provides computer-generated plots of this concept. (CW)
