Presented are nine physics demonstrations. Topics include mechanics, magnetism, mass, optics, friction, and molecular motion. An illustration and questions are included for each. (CW)

Presents ideas on how common household light bulbs can be used to develop interest in learning physics. Focuses on supermarket data taking and analyses, filament temperatures, detective work with three-way bulbs, and lifetime statistics. (YP)

Describes the design and fabrication of a classroom hologram and activities utilizing the hologram to teach the concepts of real and virtual images to high school and introductory college students. Contrasts this method with three other approaches to teach about images. (MDH)

An incident light ray parallel to the optical axis of a parabolic mirror will be reflected at the focal point and vice versa. Presents a mathematical proof that uses calculus, algebra, and geometry to prove this reflective property. (MDH)

Explores the potential of the RAY learning environment in improving learning about optics. Results indicate that this environment, which includes a flexible ray-tracing simulation, had a significant effect on the spontaneous and correct use of the model by students in solving problems and a limited effect on conceptual understanding, but promoted…

This paper describes an attempt at evaluating a potentially critical "detail" of teaching practice; that is, using a particular diagram to illustrate the imaging role of a converging lens. This "basic" diagram has been designed to contribute to help students overcome the well-known "travelling image" syndrome. We conducted a comparative study with…

This instructional manual contains 20 learning activity packets for use in a workshop on lasers and fiber optics. The lessons cover the following topics: what a laser; coherent light; setting up the laser; characteristics of the laser beam; scattering of light; laser beam divergence, intensity, color, ophthalmology, and reflections; directivity of…

Describes apparatus needed and instructions for conducting four experiments. Experiments focus on light waves, measurement of contact resistance, demonstration of longitudinal waves, and a simple method of measuring the refractive indices of transparent plates and liquids. (JM)

Describes student projects on applications of solar energy optics to home design. Project criterion (requiring sketches and detailed calculations of time rate of energy flow/production) is that half the heat for the heating season be taken from the solar resource; calculations must be based on meteorological data for a specific location. (JM)

Presents NASA astronomy publications by subject: Earth; Moon; Mercury and Venus; Mars; Jupiter and Saturn; Planets (general); Comets, Meteors, and Asteroids; Sun; Astronomy from Various NASA Missions; Miscellaneous Astrophysics; Telescopes and Instrumentation; and Extra-Terrestrial Life. Includes listing of NASA Technical Conference Proceedings…

Explains the aims behind the first six regional facilities that are being established at universities that already have strong state-of-the art programs in the areas of their grants. Gives a brief look at the facilities and what each has to offer. (GA)

Examines the use of a computer simulation program as a tool to help in the understanding of wave phenomena. After analyzing some of the main difficulties and common misconceptions about waves, features of the "Making Waves" software package are described. Figures showing a typical monitor display are presented. (YP)

This case study describes 1 teacher's implementation of a modified version of Glynn's Teaching-with-Analogies model with a grade-10 optics class on refraction of light. (PR)

Outlines 39 physics demonstrations that utilize simple objects such as coffee and soda cans to illustrate scientific concepts. (12 references) (MDH)

Discussed are some areas of overlap between physics and astronomy. Topics include solar power, fusion reactions, atmospheric refraction, solar spectrum, Doppler effects, Hubble constant, quasars, redshift and the expanding universe, sunspots, sundial construction, solar spectroscopes, the moon, optics, wave theory, the history of science,…
