It turns out Al Wallace got my old space at Kitsap. It's a little hovel in what we call "The Outback," the octagon furthest from the administrative offices, an easy place to hide if you're really quiet. It?s triangular in shape and somewhat awkward, but that?s what you get when an architect knits together a bunch of 5,000-square-foot octagons in a…

Describes an experiment demonstrating Lenz's law by measuring a magnet falling through a copper tube compared to a nonmagnet falling. Presents diagrams and pictures showing the apparatus. (YP)

Describes the use of magnetic field probes interfaced to a microcomputer in measuring the magnetic field in and around a solenoidal "Slinky" spring toy carrying a current of a few amps. (JRH)

Describes a simple, inexpensive system that allows students to have hands-on contact with simple experiments involving forces generated by induced currents. Discusses the use of a dynamic force sensor in making quantitative measurements of the forces generated. (JRH)

Presents a simple but effective experiment that uses ultrasonic transducers and some basic electronics to study the speed of sound using the Doppler effect. Eliminates the noise problems associated with most sound experiments. Discusses the theory, and describes the apparatus and procedure. (JRH)

Describes an experiment that uses the ultrasonic transducer for demonstrating the Fourier components of waveshapes such as the square and triangular waves produced by laboratory function generators. (JRH)

Presents experiments that use Microcomputer Based Laboratory (MBL) techniques to enable freshmen physics students to investigate complex systems, such as nonlinear oscillators or coupled harmonic oscillators, at a level appropriate for an independent project. (JRH)

Describes simple inexpensive modifications to existing equipment that facilitate the computerization of interference and diffraction experiments done in introductory laboratory courses. (JRH)

Presents three motion experiments that use magnetic switches for marking position and time involving an inclined plane, an air track, and sprinting. (JRH)

Presents activities using thermocouples to investigate the temperatures at which candles burn and popcorn pops. (MKR)

Describes a course for science education majors that explores the uses of computer-interfaced experiments in a variety of interesting activities. Several examples of biology experiments are given. (ZWH)

Contains an illustration and text to aid in describing the DynaPulse 200M Education Edition microcomputer-based laboratory (MBL), which combines interactive software with curriculum and medical instruction to teach students about the cardiovascular system. Review includes key features of the software, cost, and ease of use. (ZWH)

Describes an experiment to study the motion of a rocket-propelled vehicle over the entire duration of the engine burn using a video system with a frame-by-frame playback and a Sonic Ranger for ultrasonic position movements. Enables students to study the impulse-momentum principle and the effects of a time-varying force. (JRH)
