Outlines and illustrates the Dartmouth approach to developing a science project. This problem-solving approach, promoted by the Thayer School of Engineering at Dartmouth College, helps teachers in guiding students in all phases of project work. (JRH)

Describes the use of a news story to discuss physics problems related to kinematics and dynamics. (JRH)

Conducted a study using activities based on historical data connected to heat and temperature to determine how and where it is possible to use the history of physics in a high school course. Analyzes episodes in which there was any allusion to history. Concludes that the history of science helps students understand the nature of science.…

Presents an activity that enables students to answer for themselves the question of how fast a body must travel before the nonrelativistic expression must be replaced with the correct relativistic expression by deciding on the accuracy required in describing the kinetic energy of a body. (ZWH)

Presents two separate models for implementing a hands-on calculus-based introductory physics course. Included in the discussion are context; purpose; topics; implementation of model one and two; and conclusion. (ZWH)

Provides instructions to make a device able to simulate the typical light pulses seen by a photomultiplier tube. Comments on circuit theory, circuit operation, and pedagogical value. (MVL)

Explains how music is digitized and digitally recorded onto tape. Also discusses the compression of digital audio signals, digital compact cassette systems, and minidiscs. (MVL)

Discusses and provides an example of reflectivity approximation to determine whether reflection will occur. Provides a method to show thin-film interference on a projection screen. Also applies the reflectivity concepts to electromagnetic wave systems. (MVL)

This article describes the recruitment and selection methods, reports how the students handled the course requirements, summarizes the feedback from the teachers, and discusses the successes and failures in achieving the goals of the astronomy master's program for middle school and high school teachers at the University of Arizona in Tucson. (MVL)

Uses a clamp-on ammeter to measure current loads of many small and major appliances. Notes its ease of use. Includes a table of amperage and wattage usage for many home appliances. (MVL)

Recommends using probability paper, also called normal probability and arithmetic probability paper, for solving probability problems. Provides six examples. (MVL)

Describes an approach for teaching with analogies in secondary science classes and gives an example using the three states of matter. (14 references) (Author/MKR)
