The function, design, and ground station requirements of the AMSAT-OSCAR non-commercial space satellite system are described, and various experiments designed for direct student participation in space communications are provided in this text primarily written for the science educator. Six chapters include: (1) an introduction to general satellite…

This module is designed to give the learner an understanding of the nature of light and how its properties are used in the design of spectrophotometers. Problems promote the use of spectrophotometers in qualitative analysis, the optical elements used in a monochromator, and the physical properties of the prism and the diffraction grating. Other…

Various approaches to the standardization of pH meters are compared and the limitations of each are pointed out. (BB)

Tests of the predictivity of the biorhythm theory using 30 staff members of a psychiatry service and 50 patients of a college health center showed low correlations between the observed and predicted feeling states. Most were not statistically significant. (BB)

This course presents the student with a performance approach to biology. Each technique is covered in standard lecture format and in guided, independent laboratories. Examinations and grading are competency-based and require knowledge of both the use and limitations of the techniques. (BB)

Simple activities are described which use paper clips and straws or a board to demonstrate the properties of the lever. (BB)

Discusses the use of laser spectroscopy in determining the presence of specific gaseous constituents. Three of currently used modes for laser detection of pollution are reviewed; (1) long-path measurements; (2) laser raman (differential absorption) measurements; and (3) optoacoustic detection. (HM)

Describes a currently used picosecond spectroscopy system capable of reliably recording picosecond events. Two areas of picosecond research are discussed: one concerns the interaction of electrons in fluids; the second, the primary events in vision. (Author/HM)

Describes the various attempts, efforts and experiments that were carried out by the leading investigators in the field in their search for electromagnetic induction phenomena. (GA)

The mixing of sediments by organisms (bioturbation) is discussed. Research techniques are discussed and data on Atlantic bioturbation rates are provided. (CP)

Reports a qualitative experiment on the contraction of gases which has dramatic appeal to arouse student curiosity. (SL)

Reports on the use of demonstration/experiment using silver ions in water purification. (SL)

Describes an experiment revealing a visual latency effect produced by the wearing of sunglasses. (SL)

Describes physics experiments and demonstrations on the measurement of electrostatic fields. (SL)

Describes a holographic method of producing a picture of a real lens, objects, and the virtual image of the objects. (SL)
