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)

The study reported here extends the investigation begun by Piaget of content effects to laboratory and naturalistic tasks. If the accuracy and completeness of the subjects' expected variables is related to content, then performance on laboratory and naturalistic tasks should differ systematically. The subjects' expected variables were measured by…

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…

Fracture mechanics is a multidisciplinary topic which is being introduced to undergraduate engineering students in such courses as materials engineering. At a recent Conference on Fracture held at the University of Waterloo, a session was devoted to fracture education. Some of the ideas presented at that session are included and discussed here.…

Abstracts based on documents from the UNESCO International Meeting on Post-graduate Qualifications of Mathematics and Physics Teachers, 1973, in Varna, Bulgaria, are presented in this newsletter. The following subjects are covered: (1) further education of teachers of mathematics and physics; (2) the system of raising the qualifications of…

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…

Presented in this translation are three chapters. Chapter I discusses the composition of forces and several theorems of geometry are proved using the fundamental concepts and certain laws of statics. Chapter II discusses the perpetual motion postulate; several geometric theorems are proved using the postulate that perpetual motion is impossible.…
