Describes several simple and inexpensive experiments designed to facilitate the study of normal and abnormal morphogenesis in the biology laboratory. Seedlings of the common garden pea are used in the experiments, and abnormal morphogenesis (tumors) are induced by a virulent strain of the crown-gall organism, Agrobacterium tumefaciens. (JR)

Author attempted to relate research in the area of musical studies with Leon Kamin's research with animals. The experiment with human subjects set out to measure the presentation of auditory stimuli without punishment as an indication of memorization processes. (RK)

Describes the construction and operational procedures of a spark-timing apparatus which is designed to record the back and forth motion of one or two carts on linear air tracks. Applications to measurements of velocity, acceleration, simple harmonic motion, and collision problems are illustrated. (CC)

Describes implementation and results of a filmed German language course at the University of Oregon, Eugene, Oregon. The series, Guten Tag: A German Language Course for Television,'' is available from the International Film Bureau, Inc., Chicago, Illinois. (RS)

A laboratory experiment is described which presents some molecular parameters of iodine molecule by studying iodine spectrum. Points out this experiment can be conducted by sixth form students in high school laboratories. (PS)

Outlines an optics course, designed for science and nonscience majors, which emphasizes phenomena rather than mathematics. Indicates that the new curriculum permits liberal arts students to learn physics as well as the relationship of physics to society. (CC)

Outlines a one-semester course on Physics of the Environment'' which is designed for physics and nonphysics majors with a one-semester physics prerequisite. Indicates that the students are content to learn about the environment thoroughly rather than a course concentrating on pollution. (CC)
