Discusses some of the difficulties in the measurement of pressure, including the use of open-ended and closed-ended manometers. Suggests the use of an analogy of a child's seesaw in teaching about manometers. Includes diagrams showing how various positions and weights on a seesaw compare with different pressure measurements. (TW)

Identifies six computer-oriented approaches to teaching concepts in chemistry. Describes courseware and equipment involved in various experiments dealing with such topics as polymer configurations, stepper motors, conductometric titration, kinetic spectrophotometry, and overlap integrals. (TW)

Outlines a simple, inexpensive way of demonstrating electroplating using the reaction between nickel ions and copper metal. Explains how to conduct a demonstration of the electrolysis of water by using a colored Na2SO4 solution as the electrolyte so that students can observe the pH changes. (TW)

Proposes a two-stage experimental approach that combines preparative chemistry and polymer characterization. Describes the simple organic synthesis of a plasticizer, the dioctylphthalate, and its direct use in the preparation of a styrene/divinylbenzene network copolymer. Discusses how to evaluate the physical properties of the resulting plastic.…

Argues for the introduction of a college level safety course for chemistry majors and surveys college catalog offerings to determine course status in American Chemical Society approved departments. Concludes that six percent of approved departments offer a formal safety course. (ML)
