Designed for first-year students of radiochemistry and atomic physics, this experiment tests the fundamental Moseley Law and introduces the method of elemental chemical analysis by X-ray fluorescence. (Author/MLH)

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)

Describes the use of biofeedback machines in biology classes which provide students with an awareness of their own brain waves and as a device to demonstrate the fact that the body responds readily to the mind. (BR)

Reports on the lab's activities as a center for the development of university language lab courses and for research into contemporary oral colloquial French, a part of the applied linguistics research area, and a center for the development of a language lab grammar for Zurich German. (RM)

Describes an experiment that illustrates the use of the preparative ultracentrifuge in isolating and purifying bacterial ribosomes, determines the sedimentation coefficients of the ribonucleoprotein particles, and demonstrates the subunit structure of the 70-S ribosome and the role of the magnesium ion in the association of subunits. (Author/GS)

Describes a laboratory experiment designed to merge the concepts and techniques of the analytical-organic-physical subdivisions and introduce the student to a decision-making situation. Presents a discussion of the use of the experiment in attaining these goals and provides typical data obtained by students. (GS)

Describes a laboratory pretest giving samples of laboratory competencies, such as observing, interpreting, and calculating. Information from the test is related to student background and to overall success in the course. A test copy and tabulated data are included. (EB)

Presents a description of the development of a laboratory-oriented chemistry course and the results noticed when the course was implemented. The syllabus was considered to be highly successful. (EB)

The program objectives are to instruct students in laboratory techniques, experimental procedures, evaluation of results, and laboratory project design. Integration of techniques which may span several areas of chemistry is emphasized in the solution of problems. Current course content of the program is listed. (GS)
