Describes a five-day, five-station oceanographic cruise off the coast of southern California designed to provide practical field experience for college students enrolled in marine science courses. (JR)

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 the arrangement, specifications, and operation of a setup designed for use as a student project to record radio storms, continuous level of the quiet sun, and scientific satellites operating near the amateur 2-m band. Included is an example of records of solar activity during 1968-73. (CC)

Discusses the use of self-paced study programs to teach physics to deaf students through lip movements, sign language, and fingerspelling. Describes several instructional problems encountered in the teaching-learning process. (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)

Describes the use of audio-visual-tutorial methods in chemistry teaching which was reinforced by color slides, study guide, and laboratory experiments. Concludes the presence of satisfactory results when a minimum rate of progress was set out in advance. (CC)

Discusses educational programs carried out by a minimum system which consists of a PDP-8/L computer with 4K memory and an ASR-33 teletype. Indicates that an entire curriculum with 450 students can be handled by simply adding some components. (CC)
