Describes the construction and operation of a simple field mill to measure atmospheric electric fields. (Author/CP)

Describes an undergraduate laboratory project that combines microprocessor programing, interfacing, and system design to produce an inexpensive multichannel analyzer. (Author/CS)

Describes a project that involves high school students in research in different disciplines at Stockholm University. Teaches students how to design a study and research plan, accomplish the work, and write a research report. (Author/YDS)

Describes the construction of a demonstration to show optical activity of table syrup. (Author/CP)

Describes the construction of a flexible coupled-cavity interferometer for student use. A helium-neon laser and phonograph turntable are the main components. Lists activities which may be performed with the apparatus. (Author/CP)

Discusses instrumentation and describes such research areas as the albedos of the brighter planets, rotation rates and atmospheres of the larger and brighter satellites, brightness changes of outer planets, asteroid rotation rates, and variable stars. (GS)

Describes an analog electronic simulator for the motion of an object projected horizontally in a vertical acceleration field. The device features adjustable values for the horizontal speeds and "gravity." Trajectories are displayed on an oscilloscope. (Author/CP)

Describes an experimental project on boomerangs designed for an undergraduate course in classical mechanics. The students designed and made their own boomerangs, devised their own procedures, and carried out suitable measurements. Presents some of their data and a simple analysis for the two-bladed boomerang. (Author/MLH)

Presents two calculations of the probability of detection of an interstellar comet, under the hypothesis that such comets would escape from comet clouds similar to that believed to surround the sun. Proposes three problems, each of which would be a reasonable term project for a motivated undergraduate. (Author/MLH)

Develops a simplified electrostatic model of the heart with conduction within the torso neglected to relate electrocardiogram patterns to the charge distribution within the myocardium. Suggests its application to explanation of Coulomb's law in general physics. (CC)

Discusses a role-playing technique used in a physics of music course that introduces students in a course for nonscientists to the thought processes and experiences of being a scientist. Students select a research project and present results as a journal article or an oral presentation at a scientific "meeting." (Author/JN)

Described is a multidisciplinary group project for undergraduate students in astronomy and physics. The students design and build a simple radiotelescope subject to a number of realistic constraints such as fixed cost, use of a standard communications receiver, and buying of supplementary building materials off the shelf.
