Describes the construction and use of a rotating-room apparatus. The device has a 48-inch diameter platform, seats four at a table, and rotates at four possible speeds. It is easily transported and erected without special arrangements. (Author/MLH)

Derives Kepler's three laws of planetary motion algebraically from conservation principles without introducing Newton's law of force explicitly. This procedure can be presented to students who have had no more than high school algebra. (Author)

Describes an experiment for the undergraduate electricity and magnetism or mechanics laboratory to investigate free and driven oscillations. The RLC circuit is pulsed with a pulse generator when free oscillation is being studied and is driven with a low-impedance sinusoidal generator when driven oscillation is being studied. (Author/MLH)

Describes an apparatus suitable for measuring magnetic susceptibility in the undergraduate laboratory. Several applications are considered in detail, and extension of the technique to nonmagnetic studies is briefly discussed. (Author)

Provides abstracts and materials requirements for 20 chromatography projects. Experiments range in complexity; some require synthesis steps, apparatus construction, or special preparation techniques. (MLH)

Describes an experiment, for the general chemistry laboratory, intended to introduce the student to infrared spectroscopy. After being introduced to the theory of molecular vibrations on an elementary level, each student receives a list of 5-7 nickel (II) ammines to be prepared, analyzed and characterized by infrared spectoscopy. (MLH)

Item analysis of a mathematics preknowledge test given to physics students revealed that significant differences existed on certain items between groups of students who had followed different mathematics syllabuses. (MLH)

Presents the rationale, general aims, course sequence, and course descriptions for a health studies program. This program requires from six to eight units for a major in this area. (GS)

Examines the employment problems of Ph.D. physicists in the traditional career areas of higher educatiion, industry, and government. Proposed solutions to the problem include not increasing physics graduate enrollment, annual manpower reports, student awareness of careers in non-traditional fields, and career mobility among older physicists. (GS)

Describes several programs of the American Association for the Advancement of Science (AAAS) Office of Science Education (OSE), including short courses offered in the natural and social sciences, mathematics, and engineering to college teachers. Discusses several OSE publications. (MLH)

States that it would be inappropriate to give in to student demands that they be taught according to their own standards, needs, and perceptions. The young must be introduced to intellectual discipline before they can appreciate its power. Outlines a curriculum design that would accomplish this goal. (GS)

Describes an experiment wherein the student can demonstrate the existence of all the thiocyanato chromium complexes, estimate the stepwise formation constants, demonstrate the robustness of chromium III complexes, and show the principles of paper electrophoresis. (GS)

Describes an experiment that will acquaint the student with the ion-exchange model, yield data which fit nicely to a computer type analysis, introduce the preparation of electrodes, provide a unique experience with elevated temperatures and ionic solvents, and provide experience in electrometric measurements.
