Describes experiments using crude isolated chloroplast fractions which demonstrate some aspects of the photosynthetic light requiring process and a number of factors affecting them. These experiments are suitable for senior high school and college courses in biology. (JR)

Discusses experimental evidence for the existence of organic material in the solar system prior to the earth's formation. Indicates that the earth could have received much of its organic compounds from meteors falling on its primitive surface. (CC)

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)

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 an experiment designed to expose the student to the classical techniques of organic dye synthesis and introduce him to a variety of modern scientific knowledge and exotic physical phenomena which he might not encounter otherwise. (Author/DF)

Describes a one-year program in which students are given lectures on instrumentation topics, acquire experience participating in campus and community laboratories, and complete individual projects to receive the master's degree. Indicates a high ability of attacking laboratory problems in students' achievement. (CC)

Describes the pedagogical use of a 12.0m x 1.0m x 0.8m electromagnet to demonstrate the properties of magnetostatic fields and the Faraday-Henry induction law. (CC)

Author discusses science discovery lessons, presents a model of one, and offers suggestions for structuring other specific lessons. (Editor/MB)
