Discusses some basic physical ideas about light scattering and describes a simple Raman spectrometer, a single prism monochromator and a multiplier detector. This discussion is intended for British undergraduate physics students. (HM)

A magnetic multipole apparatus suitable for the physics teaching laboratory is described. The apparatus enables the student to measure the magnetic field configuration of a single large coil, and of systems of one or more small coils. (Author/DS)

A technique is presented for producing holograms using equipment which is already in the possesion of the majority of college physics departments, which includes a slightly modified Michelson interferometer, a helium-neon laser, and a long focal-length lens. Production of high quality holograms has been achieved by inexperienced undergraduates…

Describes the nineteenth century wave machines which can be found in the Smithsonian Institution, at Kenyon, and other colleges. Included is information about the apparatus, queries, and descriptions of different wave machines and how they work. Information included may inspire the reader with similar apparatus to repair it and use it again.…

Describes a method for constructing undergravel filters made from common materials to provide suitable habitats for a diversity of aquatic organisms. (CS)

Describes a portable fluid power engineering laboratory and class demonstration apparatus designed to enable students to design, build, and test multi-actuator circuits. Features a variety of standard pneumatic values and actuators fitted with quick disconnect couplings. Discusses sequencing circuit boards, microcomputer control, cost, and…

Highlighted are characteristics of programs written for a pocket-sized programmable calculator to analyze mass spectra data (such as displaying high resolution masses for formulas, predicting whether formulas are stable molecules or molecular ions, determining formulas by isotopic abundance measurement) in a laboratory or classroom. (CS)

Suggestions are discussed for the teacher regarding a way in which hazardous chemical wastes can be disposed of by schools collectively, with primary responsibility on the teachers. (SA)

Presents a classical demonstration of polarization for high school students. The initial state of this model, which demonstrates the important concepts of the optical and quantum problems, was developed during the 1973 summer program on lecture demonstration at the U.S. Naval Academy. (HM)

Describes briefly three experiments, which are presented by three physics teachers to share their ideas with other teachers and readers. These experiments are: (1) a simple hazemeter for window pollution assessment; (2) the speed of light; and (3) the ball-bearing electric motor. (HM)

Describes potentially dangerous classroom situations involving toxic minerals. The intent of the article is to make students aware of the dangers so that they may act responsibly in health-related decisions as professional geologists. (Author/SA)

Background information on the structure of flowers is given prior to materials, construction, methods, and uses of the dynamic flower model. Several games are described that can be played with the model. (SA)

Describes a constant-temperature observation chamber and includes instructions on constructing the apparatus. Suggestions for use are given as well as problems that might be encountered. (Author/SA)

Directions are given for construction of an astrolabe capable of yielding two celestial coordinates: altitude and azimuth. Potential uses are included for both young and older children. Quantitative measurement activities related to celestial motion and position are given. (SA)

Diagrams and explains construction of an actograph which quantitatively records daily movements of animals for a 24-hour period. Combines use of a kymograph and the teetering box of Palmer. Biorhythm activities with fiddler crabs, cockroaches, and hamsters are suggested. (CS)
