This paper describes the building and use of an inexpensive, compact audio-oscillator for use in the language laboratory and classroom. Master tapes are coded with low frequency tones which are heard as beeps in fast forward or rewind and help the student find his place. (AM)

Weights suspended from a lever arm separate evacuated hemispheres allowing estimation of atmospheric pressure to within five percent of the barometric reading. An illustration and a reference to von Guericke's demonstration are provided. (GH)

Describes a project to produce a series of laboratory manuals and instructional materials in which nuclear experiments are presented for the undergraduate advanced laboratory. The manuals are being compiled in the areas of physics, chemistry, geology and environmental sciences. (BR)

Teacher input is essential to facility planning. A feasibility study also determines needs by focusing on community characteristics and needs, instructional efficiency, safety, and future plans. (MW)

This paper describes the psychology laboratory at Nebraska Wesleyan University and the efforts of the small department which participated in the design and development process. The lab consists of 26 rooms, mostly small cubicles, and covers approximately 3,800 square feet. Each area of the lab is described in terms of its design and function.…
