Noting the lack of time in the 2-year program and the impatience of most student technicians, the author suggests that physics should be taught inductively. Laboratory experiments with understanding of the underlying physics principles are suggested as the appropriate center of activity. Examples are given of this emphasis on experimentation as…

Describes how to construct a moving reference frame for the quantitative measurement of the Coriolis effect. (MLH)

Discusses a photograph of an unusual combination of lunar halos: the 22-degree refraction halo, the circumscribed halo, and a reflection halo. Deduces the form and orientations of the ice crystals responsible for the observed halo features. (MLH)

Looks at current attempts to bridge the brain/mind gap. (Editor)

Describes a validation study in which tenth-grade students received instruction on electric circuits using a learning hierarchy of concepts constructed from a task analysis procedure. (MLH)

Demonstrates that the number of kilometers of highway in the U.S. tends to grow exponentially and discusses what can be done to modify this growth. (MLH)

Describes a simple apparatus that measures atmospheric pressure within 20 percent of the accepted value using a syringe, spring scale, and a ruler. (MLH)

Describes and evaluates introductory physics homework problems done in conjunction with student-performed demonstrations. Discusses them within a process approach to instruction consistent with Piaget's developmental theory. (MLH)

Describes an interactive computer-assisted linear least-squares curve-fitting program that allows students to generate basic tables, plots, and fits to their data. (MLH)

Describes the topics covered and methods used in a liberal arts astronomy course on photographing the night sky. (MLH)

Describes the basic acoustical principles of percussion instruments whose vibrating members are multidimensional. (MLH)

Describes acoustical systems utlilized for mapping ocean floors. (SL)

Provides an historical chronology of events related to understanding the photoelectric effect. Focuses on the early history, the mystery of the photoelectric effect, the contributions of Albert Einstein and Robert Millikan to the field, and hands-on activities that demonstrate the phenomenon to students. (DDR)

Describes how to construct a form of a Kelvin Electrostatics Generator from readily available components and provides an explanation of how it works. The device can generate 10-12 mm long sparks in the air. (DDR)

Provides a description of an experiment in which students use a standard ultraviolet and intense blue (UV/VIS) spectrophotometer to measure the amount and energy of light. Explains how a simple measurement of the transmission spectrum of sunglasses can reveal differences between brands and can illustrate the destruction of the earth's ozone layer.…
