Described are the purposes, laboratory set-ups, and procedures of four classroom experiments: ultrasound speedometer; vibrating-bar depth gauge; folding three-dimensional model of equipotential surfaces; and a simple optical system for the reconstruction of images from computer-generated holograms. Diagrams and pictures are provided. (YP)

Describes an experiment in which a recycling oscillator has been designed having a fiber optic data link that closes the loop. Outlines the use of this wink-around system to determine the speed of light and suggests additional application for measuring integrated circuit propagation delays to subnanosecond resolution. (GS)

Describes a laboratory experiment in which the experimental data agree well with the empirical law. Demonstrates that transparent materials reflect light. (CP)

Describes experiments for determining the dielectric constants of liquids and measuring capacitor dissipation. (SL)

Details construction of an inexpensive electronic auditory device in which the resistance in parallel with the device is inversely proportional to the frequency of sound produced. (CP)

Describes the use of storage oscilloscopes in five physics experiments, in lecture demonstrations, and in improved measurement techniques. (GS)

Describes experiments in which a bipolar transistor is used to examine the behavior of a simple circuit. Also addresses problems in teaching the related concepts. (The experiments can be modified to incorporate devices other than bipolar transistors.) (JN)

Describes laboratory experiments suitable for teaching the principles of digital electronics and computer interfacing to undergraduate chemistry students. Also describes the program for teaching laboratory uses of computers. The program functions to teach principles of computer interfacing while displacing as little chemistry as possible from the…

Describes several different philosophies of mind with each philosophy's explanation of the mind-body problem. Philosophies discussed include dualism, materialism, functionalism, radical behaviorism, logical behaviorism and central-state identity. (DS)

Describes an electronic technique for making a series of timing measurements in quick succession, using the signal from one photodiode. Two undergraduate experiments, one on linear momentum and the other on angular momentum conservation, are included. (HM)
