Discusses five experimental methods used by senior high school students to provide an accurate calibration curve of magnet current against the magnetic flux density produced by an electromagnet. Compares the relative merits of the five methods, both as measurements and from an educational viewpoint. (JR)

Briefly outlines the theoretical basis of the phenomenon of photoconductivity and describes a simple experiment which demonstrates the photoconductive properties of cadmium sulfide. (JR)

Based on an unpublished doctoral dissertation, Department of Psychology, University of North Carolina at Chapel Hill, 1969. (RS)

An experiment assigned in a role-playing'' modern physics lab for juniors who are challenged to obtain accurate measurement with suboptimum apparatus through correct analysis. They also investigate the influence of systematic errors using a small computer. (DF)

An unusual science program which centers around a vivarium and is based on the notion that students learn science by doing it, not just talking about it. (DF)

Describes a physics laboratory course which operates without written instructions and with no required experiments. Course is based upon one- or two-week topics in mechanics, heat, electromagnetism and optics with a student-designed experiment in modern physics as an extended project. (DF)
