Reports the addition of new courses in a community college made possible with the acquisition of electron microscopic equipment. (GB)

Describes the use of the air track for some instructive physics experiments. The technique of combining an air track with strobe photography is discussed. Bibliography. (LC)

Plan for a language laboratory, designed from the teacher's point of view, where the isolation of students is avoided and maximum exploitation of facilities is allowed. (FWB)

Suggesting that selected research activities be integrated into engineering technology programs to give students experiences in new technology, this article discusses a project incorporating teaching, research, and service. A photograph and description of the solar experiment unit resulting from the project are provided. The unit runs on air,…

Provides background information, apparatus needed, and procedures for an experiment to measure transient response of a stirred vessel. The inexpensive apparatus can be used for two different experiments, reducing cost per experiment. Both experiments use salt dilution as the method of demonstration. (Author/JN)

Cathodoluminescence is visible light emitted from a specimen when it is bombarded with electrons. A technique known as cathodoluminescence petrography can provide information especially useful in studies or courses related to mineralogy and petrology. The technique is briefly presented, along with examples to illustrate typical results. (Author/WB)

A technician auto analyzer (consisting of six modules: sampler, multichannel peristaltic pump, dialyser, heating/incubation bath, colorimeter, and recorder) was modified by using key modules and substituting standard equipment for others; spectronic 20 with homemade flow cell for colorimeter module. Descriptions and diagrams of the apparatus are…

The use of a logarithmic amplifier preceding an oscilloscope's vertical amplifier is described for physics teachers who want to demonstrate the exponential decay nature of some phenomena. (Author/SA)

Described is an experiment that explores the relationships between conscious motor activity and autonomic processes such as breathing, blood pressure, and heart rate. Procedures for the construction and calibration of ball ergographs are outlined. (CS)
