Described is an experiment to investigate the plasticizer content in polyvinyl chloride (PVC) products. The experiment is designed for college students using an instrumental analysis laboratory. (RH)

Describes a learning project in analytical chemistry in which students are required to select instruments from the manufacturers' literature that would be suitable for a given analytical problem. Several examples are given. (SA)

Describes modules designed to enable a student to learn a measurement technique and familiarize himself with measurement instrumentation independently of a laboratory course. Presents an example of a module involving the measurement of electrical resistance and lists other modules that have been developed. (GS)

Describes an experiment suitable for an instrumental analysis or quantitative analysis course. (BB)

Using fourier transformation methods in nuclear magnetic resonance has made possible increased sensitivity in chemical analysis. This article describes these methods as they relate to magnetization, the RF magnetic field, nuclear relaxation, the RF pulse, and free induction decay. (CW)

Describes a course which used a student project approach and was designed to replace traditional instrumental analysis. Presents the criteria used for project selection and gives examples of student projects in 1974. (GS)

Discussed are two techniques that can be used to directly test the theory that the plates which make up the crust of the earth are still moving. Described are the use of satellite laser ranging and very long baseline interferometry. Samples of data and their analysis are provided. (CW)

Outlines benefits of integrating optical instruments in computer-based instructional systems in a science classroom including budget, immediacy, pictorial records, and graphic enhancement. Presents examples of investigative activities involving optical instruments and images digitized for computer-based manipulation. (JRH)

Using Fourier transformation methods in nuclear resonance has made possible increased sensitivity in chemical analysis. This article describes data acquisition, data processing, and the frequency spectrum as they relate to this technique. (CW)
