Reviews the basic theory underlying the lift and drag forces of a magnetically levitated vehicle riding over a continuous sheet guideway. Included are descriptions of the future vehicle characteristics and the students' construction of a superconducting magnetically levitated merry-go-round demonstration apparatus in a laboratory experiment. (CC)

Discusses the offering of a course in chemical and industrial hazards for junior and senior chemistry majors at City College of New York in 1972. Suggests inclusion of laboratory and industrial safety education as a formal part of chemistry or science curricula. (CC)

A description is provided of activities for a junior high school science and social studies unit on teaching the scientific method and interrelationships between the scientist and the social scientist. (Author/KM)

Presents ideas from readers on techniques and equipment that might be useful in teaching secondary school science. Suggests how to construct cheap wall charts, modify a vacuum cleaner into a blower, construct a stereo microscope lamp holder, and outlines simple physics laboratory experiments. (JR)

Considers the role of languages and European culture in developing language programs. (RK)

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)
