Discusses chemical experiments on determination of triglyceride concentrations in biological samples by using 1,4-dihydro-3,5-diacetyl lutidine as a basis in absorbance measurements. (CC)

Discusses procedures of using the selective absorption properties of manganese dioxide to prepare a short-lived source from the cerium-144/praseodymium-144 system. (CC)

Describes a method of recording the number of particles scattered at various angles for different impact parameters in an experiment illustrating the Rutherford scattering of alpha particles. (JR)

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)
