Describes a method to teach introductory astronomy students about the phases of the moon. Uses video techniques to aid students in developing the skill of visualizing the same phenomenon from different frames of reference. (JRH)

Presents the theory behind the mechanics demonstration that involves projecting a ball vertically upward from a ballistic cart moving along an inclined plane. The measured overshoot is believed to be due, in part, to the presence of rolling friction and the inertial properties of the cart wheels. (JRH)

Describes learnings originating from a simple pendulum simulation using "interactive physics" simulations. Discusses tension in the rope, acceleration of the pendulum bob, and initial displacements. (JRH)

Simulates the problems of rocket propulsion, hovering, and soft landing. (GS)

Describes three computer programs which operate on Apple II+ microcomputers: (1) a menu-driven graph drawing program; (2) a simulation of the Millikan oil drop experiment; and (3) a program used to study the half-life of silver. (Instructions for obtaining the programs from the author are included.) (JN)

Suggests using a "bed of nails" (array of nails on a board) as a resistance demonstration where steel balls pass through the lattice of nails like electrons through metal. Although weaknesses of Drude's electrical conduction model are noted, the activity is recommended since it clearly illustrates drift velocity. (DH)

Newton's laws can be illustrated by having physics students participate in various activities while on roller skates. Several examples of such activities (including photographs) are provided. (JN)

Describes an experiment used to demonstrate basic physics concepts regarding acoustic waves used by oceanographers to obtain seabed profiles. (ZWH)

Discusses making a computer-simulated rainbow using principles of physics, such as reflection and refraction. Provides BASIC program for the simulation. Appends a program illustrating the effects of dispersion of the colors. (YP)

Describes the use of the computer software "Graphs and Tracks" a tool for interactive computer instruction, in teaching one-dimensional kinematics concepts and connecting these concepts to their graphical representations. Provides ordering information. (JRH)

Describes two laboratory exercises corresponding to studies of statics and dynamics to illustrate the concept that the combination of real and simulated laboratory tools, with some real data being recorded in computer-aided form, can result in a very sound understanding of physical principles. (JRH)

Discusses the realities of implementing a computer-assisted program in high school level science classes, offering some practical suggestions for making such a program successful. Also includes information on several software packages for interfacing microcomputers to sensing equipment. (JN)

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)

Presents a problem to determine conditions under which two identical masses, constrained to move along two perpendicular wires, would collide when positioned on the wires and released with no initial velocity. Offers a solution that utilizes the position of the center of mass and a computer simulation of the phenomenon. (MDH)

Evaluates a pair of workshops conducted by the Physics Courseware Evaluation Project. Presents data collected on computer tool needs of the teachers, microcomputer-based laboratory probes usage, spreadsheet usage, software usage, effectiveness of technology in the classroom, and teacher involvement with computers. Reports that high school teachers…
