Describes an investigation involving acid hydrolysis and using both volumetric and kinetic techniques. Presents examples of the determination of the rate constant and its variation with temperature. (GS)

Describes a survey of experiments including a stringed instrument experiment and discusses other instructional uses of cartridges. Includes information on the characteristics of cartridges. (GH)

Describes a take-home experiment requiring only running water, a flat surface, a fluorescent light, and a ruler. Suggests elaboration of the experiment. A photograph is included. (GH)

Describes a physics laboratory experiment for nonscience majors intended to illustrate indirect experimental methods of sciences treating objects too small for sensory observation. The student explores and attempts to identify an object in a closed container, using provided experimental tools and small openings in the opaque lid. (MLH)

This learning module is intended to illustrate the functioning and uses of bridge circuits. The discussion and laboratory procedures suggested in the module presume familiarity with basic concepts of electronics such as voltage, current, resistance, capacitance, inductance, phase, and knowledge of such skills as breadboarding circuits from…

This laboratory unit is designed for a minimum of 15 hours of work. Experiments are designed to fit a complete unit of study on energy, and require only simple, inexpensive, or easily constructed equipment. Motivational questions, objectives, support information, feedback items, and follow-up activities are incorporated into the various…

The stress-inoculation paradigm for helping clients deal with pain consists of education about the psychological dimensions of pain, training in a number of coping skills relevant to each dimension, and practice in applying these skills to the noxious stimulus. Presented are two studies, the first of which represents a component analysis of stress…

This second volume, a compilation of reprints of experimental notes in physics, was prepared by the American Association of Physics Teachers (AAPT) Committee on Apparatus and by the AAPT Executive Office in response to requests received by the Association for a completely new edition. The goal of the Committee was to provide a selection of…

Twelve sections of students and three instructors were used in this study in which inquiry was examined in the context of two teaching methods. The conventional or traditional method used traditional laboratory exercises as the main format. This was considered the control method. An extended laboratory method with the student choosing his problem…
