Describes an experiment suitable for high school physics classes in which students determine the wavelength of electromagnetic radiation of u.h.f. television transmissions. Elaborate equipment is not required, and details are given for the construction of a dipole. (JR)

Discusses the use of a modified air table to conduct laboratory experiments which eschews research-oriented lab experience and concentrates on concepts learned in classroom. Includes a description of apparatus construction, sample instruction sheets, and a list of laboratory concepts with their relationships to classroom materials. (CC)

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)

Presents a teaching unit on the Langmuir absorption isotherm suitable for advanced secondary school chemistry classes. Describes the experimental investigation of the isothermal adsorption of sulfur dioxide on charcoal, and discusses the derivation of the Langmuir equation and some applications. (JR)
