Suggestions are provided for demonstrating vector cross product and vector dot product using manipulatives. Also provides a method for producing quick and inexpensive diffraction slits and ideas for demonstrating two-dimensional diffraction. (JM)

Describes a project designed to develop 50 tutorial lessons for students having difficulty with specific types of physics problems. Because the intent was to tutor problem solving rather than teach physics concepts, lessons were designed for use after classroom instruction had occurred. Includes project goals, development, implementation, results,…

The Center for the History of Chemistry (CHOC), located at the University of Pennsylvania, was officially inaugurated in March 1983. Highlights inaugural ceremonies; discusses CHOC aims, activities, and exhibits. Includes comments on Center for Physics History, industry role in perserving corporate history, chemists honored on United States…

Describes a simulation in which students play roles of computer parts. Also describes cartesian divers and eye imagers prepared from empty detergent bottles and old 35-mm film cans respectively. Suggests using the divers and imagers as free give-aways during meetings or workshops. (JN)

Discusses problems associated with teaching physics in English and students' native languages. Reviews studies on the topic, including Whorf's linguistic relativity. Includes suggestions for further research. (SK)

Outlines several laboratory procedures and demonstrations including electric fields using sawdust, experiments with capacitors, particle spacing in a vapor and a liquid, metrology, momentum, Moire patterns and interference fringes, equipping for practical electronics, and using programmable calculators for rapid plotting of graphs. (DS)

Describes a method to demonstrate induction heating by placing an ordinary mercury thermometer in a high frequency magnetic field and observing the temperature rise. Also describes an ice calorimeter for measuring the mechanical equivalent of heat. (SK)

Examines the state of physics in 1931, the predicted and actual states of physics in 1981, and predictions for 2031. Focuses on general conditions such as economy, energy (fossil, solar, nuclear fission, fusion), physics research, and physics publications. (JN)

A National Academy of Sciences conference was held in October, 1981 in Washington, D.C. to provide dialogs with key government officials and to suggest alternatives for wise allocation of limited resources to control damage to the United States' scientific and technological enterprise. Viewpoints and key recommendations are reported. (JN)

Describes the diffusion of water molecules with terminology adopted from the physical sciences. Presents a set of student exercises (with answers) relating to the topic. (SK)

Summarizes "you do it" activities presented at the 1978 South Australian Science Teachers Association Conference. Topics include microscope use and maintenance, chemical slide cells, chemical models, sound waves, microwaves, astronomy, plant keys, reading geological maps, and natural dye processes. (DS)

Structure of physics can be treated as an instructional variable by teachers who make the choices: defined versus derived concepts, operational versus paraphrase definitions, and theoretical versus empirical relationships. Operational definitions and empirical relationships are recommended for beginning students; paraphrase definitions and…

Discusses various topics in microelectronics to aid those teaching modern electronics for the first time, including, among others, the slang name "micro," attitudes of examining boards, rapid obsolescence of electronic devices, costs, analog systems, and digital systems. (SK)
