Proposes that introductory physics courses extend the analysis of one-dimensional motion to a more sophisticated level. Gives four experimental setups and graphical analysis of the distance, velocity, and acceleration in the vertical and horizontal directions. (WRM)

Describes a model that (1) convincingly demonstrates a particle model of gas behavior, (2) can be used by students, (3) can be mass produced, and (4) illustrates other properties of matter such as simple crystal structures and states of matter. (WRM)

Play involves unstructured activity that is freely entered into and intrinsically rewarding. When children engage in play there is little intentional learning. There are no lesson plans. There are no daily objectives or specific learning outcomes. Incidental learning can cause relatively permanent changes in the way one thinks; accidental learning…

This paper documents the dynamics of the social interactions within two small groups of sixth grade students as they solved problems and attempted to understand the concepts related to the nature of matter and molecular theory. Similarities and differences of social interactions between the two groups are compared, and interpretations presented…

The data for this study were obtained from a sample of 117 biology majors enrolled in an introductory biology course. The Diffusion and Osmosis Diagnostic Test, composed of 12 two-tier items, was administered to the students. Among the major findings are: (1) there was no significant difference in scores of male and female students; (2) math…

Unified Technical Concepts (UTC) is a modular system for teaching applied physics in two-year postsecondary technician programs. This UTC laboratory textbook, the second of two volumes, consists of 45 learning modules dealing with basic concepts of physics. Addressed in the individual chapters of the guide are the following topics: force…

This concept module on momentum is one of thirteen modules that provide a flexible, laboratory-based physics instructional package designed to meet the specialized needs of students in two-year, postsecondary technical schools. Each of the thirteen concept modules discusses a single physics concept and how it is applied to each energy system. This…

Ten experiments and 27 activities are presented in this handbook. The experiments are related to collisions, energy conservation, speed measurements, thermometry, calorimetry, gas properties, wave motions, and acoustic problems. The activities are concerned with stroboscopic photographs in collision, elastic impact, mass conservation, exchange of…

This document presents an outline for a 135-hour course designed to provide the student with all the skills, technical knowledge, safety practices, and general information that is required to understand the theory of operation, to diagnose, and to service the units that make up the power flow system of the automobile. The course of study includes…

Produced for public interest, the Environmental Education Group has prepared this two-part review of the current state of energy utilization, the nature of the energy crisis, and approaches to energy production. The major section is a presentation of alternative sources of energy that are neglected, are of possible aid in the near future, or are…

This booklet is one of a set of eight designed to be used in a self-paced introductory chemistry course in conjunction with specified textbooks and computer-assisted instruction (CAI) modules. Each topic is introduced with a textbook reading assignment and additional readings are provided in the booklet. Also included are self-tests (and answers),…

Describes the construction of an inexpensive apparatus which utilizes the oscillatory motion of 60 cycle AC current in conjunction with an electromagnetic to illustrate various principles and processes in geology. (SL)

Describes the construction of an inexpensive visual aid to be used for explaining the dynamics of gases. (CP)
