A simple experiment is proposed that can provide the student with some insight into the chemical properties of solids. It also demonstrates the relationship between the Gibbs free energy of formation of an ionic solid and the emf of an electrochemical cell. (DF)

Describes the use of Marchant 1016PR with a magnetic tape reader, Monroe 1665 with a punchcard reader, and Hewlett-Packard 9820A with an X-Y plotter to conduct introductory physics laboratory programs. Indicates that the course allows more physics to be done in the same amount of time. (CC)

Discusses training recommendations issued by the Chemical and Allied Products Industry Training Board and the two related methods in use. Emphasizes that the technician job is worthwhile in its own right rather than a step toward the technologist level. (CC)

Describes the use of a simulation lesson which is written in TUTOR language for the PLATO computer for the purpose of separating a mixture of four ions with known identity. Indicates that students have more freedom to experiment than in laboratories in other traditional computer-assisted programs. (CC)

Describes the use of two polarizing lenses, a yellow filter, an oatmeal bos, a piece of cardboard, a 1,000 ml beaker, and an overhead projector to demonstrate compound optical activity to large classes. Indicates the presence of an accuracy within 1-2 degrees of usually acceptable data. (CC)

Describes the errors in the sugar-cube experiment related to radioactivity as described in Project Physics course. The discussion considers some of the steps overlooked in the experiment and generalizes the theory beyond the sugar-cube stage. (PS)

Describes apparatus which can be constructed to allow students to experiment and collect data for understanding various aspects of simple motion of objects. Detailed instructions are given. (PS)
