Bernoulli's theorem can be better understood with the aid of Newton's laws and the law of conservation of energy. Application of this theorem should involve only cases dealing with an interchange of velocity and pressure within a fluid under isentropic conditions. (DF)

Describes a belt hook that is both functional and can be used to demonstrate the center of gravity. (MLH)

Discusses theories and research concerning the radiation produced by electrons when they are accelerated centripetally in particle accelerators. (MLH)

Describes how physics concepts can be taught by relating them to pleasant experiences. (MLH)

Diagrams and photographs are incorporated in an explanation of the physics involved in the skills of diving and swimming. (CP)

Illustrates the phenomenon of the "difference tone" in music, using simple physics. Describes how this phenomenon can be demonstrated with a flute. (MLH)

Presents a version of the periodic chart in which the elements are placed in concentric circles and lobes based on the modern knowledge of nuclear and atomic structural relationships. (MLH)

Describes a set of audiovisual materials entitled "Women in Science," which includes audiotaped interviews with six women scientists, accompanied by 35-mm slides and an article about each scientist. (MLH)

Combines coordinate systems, planetary positions, use of the celestial globe, and synodic period in a graphing exercise. Information is given to duplicate an occurrence of 1940 in which five naked eye planets were simultaneously visible. (CP)

Provides tables and graphs that give a complete and simple picture of the relationships of image distance, object distance, and magnification in all formations of images by simple lenses and mirrors. (CP)

Reviews the basic principles and methods of nuclear chronalogy or radiometric dating. Includes rubidium-strontium dating, radiocarbon dating, and an outline of recent findings. (MLH)

Discusses teaching the minimization of area and distance, such as finding the minimum length of expressway connecting four cities by using an analogy of a soap film between two Lucite plates. (MLH)
