While science films can differ widely in their content and purpose, the making of such films rests on a pattern of principles, techniques, and matters of routine. This book traces that pattern and presents descriptions of how some particular problems were tackled previously. The history and state of the medium are overviewed, with information on…

Brief suggestions for laboratory and classroom instruction in various chemistry topics are provided. (CP)

Reviews a cooperative program in which a number of nearby chemistry departments combined to purchase a mobile spectroscopy laboratory housed in a step-van truck. (SL)

Described is an approach for teaching the concept of mass to elementary students. A method for making simple balances and weight sets is also given. (MR)

A way to enlarge the projected image of solar eclipse onto a viewing surface is presented. (MR)

Presents a set of guidelines for the selection of electronic calculators with features appropriate for junior high and secondary school students. (CP)

Describes an experiment to introduce students to qualitative and quantitative aspects of neutron activation analysis. (SL)

With an aquarium and a few tools, a simple apparatus to quantitatively illustrate absorption rates of light passing through fresh, salt, and other waters (such as distilled water) can be constructed. Students learn that extinction rates are different and that the intensity/depth relationship is exponential. (DH)

Describes the trend toward the use of electronic instrumentation to monitor and measure various parameters in chemical reactions. Stresses that a knowledge of the operational relationships involved in such instruments is essential for students beginning in science. Discusses electrostatic charges, semiconductor crystals, electronic conductors,…

Describes a new laboratory technique for working with small samples of compounds used in nuclear magnetic resonance (NMR) analysis. Demonstrates how microcells can be constructed for each experiment and samples can be recycled. (TW)

Describes a quantitative experiment designed to demonstrate buffer action and the measurement of buffer capacity. Discusses how to make acetate buffers, determine their buffer capacity, plot the capacity/pH curve, and interpret the data obtained. (TW)

Discusses general construction principles for miniaturized laboratory glassware. Describes a prototype experimental kit that allows the carrying out of all standard laboratory operations and discusses a trial use of the equipment with students 16- to 17-years-old. (CW)

Traces the development of instruments used in spectrophotometry. Discusses how spectrophotometric measurements are made. Describes the color comparator, the filter photometer, and the spectrophotometer. Outlines the evolution of optical systems, including light sources, the monochromator, the photodetector, double-beam optics, and split-beam…

Describes: (1) the construction of a variable-volume resonator and Raleigh-disk resonance detector from simple materials; and (2) a learning aid for performing 60 experiments in basic electricity and electronics (consisting of a circuit board, components, and mask sheets). Illustrative experiments are included for both apparatus. (DH)

Since 1979, high school teachers from urban and rural areas of northeastern Ohio have brought their students to visit the College of Wooster Chemistry Department to learn about instruments. Rationale for the program and program activities are described. (JN)
