This transition, observed with an inexpensive ultraviolet photometer, is a potentially useful experiment for an advanced freshman class because it introduces several concepts of general physical interest. (DF)

In this second article on thin layer chromatography six kinds of experiments are suggested for science teachers to use in schools. (PS)

Discusses the use of an integrated circuit operational amplifier in an introductory electronics laboratory course for undergraduate science majors. The advantages of this approach and the implications for scientific instrumentation are identified. Describes a number of experiments suitable for the undergraduate laboratory. (Author/DF)

Describes a program that attempts to bridge the gap between class lectures and laboratory. Students are involved in individual investigations. Effective use of undergraduates is made for instructional purposes. (PS)

Describes material used in a first semester introductory physics laboratory for nonscience majors. The computer is used for data manipulation and in some cases, computer programs allow simulation of experiments with the possibility of altering values of parameters or experimental details. (Author/TS)

Describes a course designed to encourage students to think in scientific terms about common musical experiences. Involves the use of electronic equipment. Listed are the objectives for eleven experiments used in the course. (Author/TS)

Experimental data, Federal and State regulations, and user data are presented to assess the safety factors of low-power lasers. General safety precautions, basic laser theory, the place of the laser in the classroom, and some introductory exercises are also presented. (Author/TS)
