Provides instructions for constructing a desk analog computer which is particularly convenient to the user and has a number of advantages over commercially available models, including lower cost for given computing power. (Author/MLH)

The use of programmable calculators for the simulation of experiments is discussed and five examples of specific applications are provided. (DT)

Describes the construction of unit cells using clear plastic cubes which can be disassembled, and one inch cork balls of various colors, which can be cut in halves, quarters, or eighths, and glued on the inside face of the cube, thus simulating a unit cell. (MLH)

Provides evaluations of several aids for teaching chemistry. Included are The Use of Chemical Abstracts, Practical Technical Writing, Infrared Spectroscopy Programs, and a film titled "You Can't Go Back." (RH)

Describes a chemistry filmstrip program, available to students as a supplementary study aid; it involves the use of a multi-slide format with four frames per 35mm frame, a hand-held plastic viewer-magnifier, and printed explanations of the visuals. (MLH)

Describes the use of balloons to show the shape of atomic orbitals and their orientation in molecules. (MLH)

Describes the construction of teaching models made from a variety of materials such as poker chips and cardboard that illustrate many chemical phenomena, including subatomic particles, molecular structure, solvation and dissociation, and enzyme-substrate interactions. (MLH)
