Describes a calibration technique for a small motor which, when driven as a generator, can be used for a speedometer. The generator output can be fed to an oscilloscope to provide a sweep in which the vertical axis is velocity and the horizontal axis, time. (GS)

Explains a method of exploiting recent interest in automobile safety to demonstrate, qualitatively, concepts of momentum and energy. (GS)

Describes a series of experiments which provide excellent evidence for different degrees of dissociation of a series of complexes and precipitate. The series is based on the copper ion as the acid and sample data are provided. (GS)

Summarizes physics laboratory experiments with applications in the biological sciences. Includes the following topics: mechanics of the human arm, fluid flow in tubes, physics of learning, the electrocardiograph, nerve impulse conduction, and corrective lenses for eye defects. (Author/MLH)

Describes a procedure for establishing a viscosity trend through a homologous series and presents sample data. (GS)

Describes various methods of rendering visible the paths followed by a laser beam for direct viewing or for photographic purposes. (Author/GS)

This document presents the rationale for laboratory work, which is alleged to be ritualistic in many schools and colleges. The rationale is that laboratories are a fertile source of memory structures called episodes, which would enhance the comprehension of abstract subject matter when associated with it. Specific and generalized episodes are…

This publication describes in detail projects for using solar energy; five major projects and five mini-projects. The major projects are: (1) Parabolic reflectors, both cylindrical and spherical; (2) Solar oven; (3) Hot water heater; (4) House heating; and (5) Conversion to electricity. Mini-projects investigate: (1) Solar computers; (2) Fresnel…

This study describes an attempt to introduce change into an educational system. A new science program (MATAL) consisting of new teaching materials, teaching strategies and training courses--was developed and implemented in kindergarten classrooms. Major hypotheses were that (1) the kindergarten is a system; educational change will be achieved…

DIRECTIONS FOR CONDUCTING A SERIES OF SCIENCE EXPERIMENTS ARE PRESENTED. THE EXPERIMENTS CONCERN THE STUDY OF HEAT AND MOLECULAR MOTION, HEAT EXCHANGE IN A MIXTURE, SPECIFIC HEAT, HEAT AND SIZE, EXPANSION OF LIQUID, EXPANSION OF AIR, HEAT OF FUSION OF ICE, HEAT OF VAPORIZATION OF WATER, LIGHT AND SOUND, LAW OF REFLECTION, PLANE MIRROR IMAGES,…

PURPOSE OF THIS STUDY WAS TO EVALUATE THE EFFECTS OF AN IMMEDIATE FEEDBACK DEVICE ON LEARNING, RETENTION, AND ATTITUDES OF 264 COLLEGE STUDENTS IN A BEGINNING PSYCHOLOGY COURSE. LECTURES WERE PRESENTED ON CLOSED CIRCUIT TELEVISION. A CONTROL GROUP USED THE DEVICE ONLY TO PREVENT COPYING OF THEIR ANSWERS BY OTHER STUDENTS. NO SIGNIFICANT…
