This teaching guide provides background information, instructions, and copies of sample cards needed for an image walk, a series of demonstrations and activities that reveal the images carried by sunlight. The three cards are used: (1) to demonstrate that sunlight passing through holes of any shape create round spots of light--images of the sun;…

Text, illustrations, and exercises are utilized in a set of six learning modules designed to instruct allied health services students and practitioners in necessary vocabulary skills and in selected job-related competencies. The first module, "Step into Medical Terminology" by Faye Ivor, teaches students to recognize the meaning of…

This publication provides information about present uses of solar energy for space, water, and swimming pool heating that are practical for the San Francisco Bay area. It attempts to provide interested persons with the information needed to make decisions regarding installations of solar heating systems. The point of view taken is that any…

This is Part of a series of 41 Calculus Based Physics (CBP) modules totaling about 1,000 Pages. The modules include study guides, practice tests, and mastery tests for a full-year individualized courses in calculus-based physics based on the Personalized System of Instruction (PSI). The units are not intended to be used without outside materials;…

Current thinking on the role of the physical environment in special education is summarized in this report. The material has been synthesized into a "position" that has been developed through widespread contacts with special educators and architects interested in the problem. The paper develops this position in nine topical areas--(1) the concern,…

As there is uncertainty surrounding black light safety, caution should be exercised in using it as a vision training tool with visually handicapped students--particularly aphakic and albino students, young students, and those taking photosensitizing drugs. The use of ultraviolet-blocking filters or lenses is recommended during black light…

Describes an activity in which young children explore the concepts of light by predicting the shape of shadows. Different configurations of light sources are used and objects are held in different positions. Sample questions to be asked of the children before, during, and after the activities are included. (TW)

Presents two methods used to measure the refractive indices and double-refraction of fibers. Experiments are described, with one involving the use of Pluta microscope in the double-beam interference technique, the other employing the multiple-beam technique. Immersion liquids are discussed that can be used in the experiments. (TW)

Describes a laboratory experiment in which benzene fluorescence is quenched by bis(acetylacetonato) copper(II). Discusses how this experiment can demonstrate a special technique used in the field of photochemistry. Provides an outline of the experimental procedure and discusses its results. (TW)

Describes several methods of executing lecture demonstrations involving the recombination of the spectrum. Groups the techniques into two general classes: bringing selected portions of the spectrum together using lenses or mirrors and blurring the colors by rapid movement or foreshortening. (JM)

Describes simple, electrical projects with dry cell batteries and lamps designed to teach children about conductors, insulators, and switches. Instructions for construction of circuits, the science ideas in each project, and suggestions for extending each of the investigations are included. (JM)

The NASA "Why?" Files is a free annual instructional distance learning program that integrates science, mathematics, and technology. The program targets 3rd through 5th grade students and uses a problem-based teaching approach. This lesson guide includes four segments, each with objectives, vocabulary, video component resources, career ideas, and…

The key to learning is student involvement! This American Association of Physics Teachers/Physics Teaching Resource Agents (AAPT/PTRA) manual presents examples of two techniques that are proven to increase student involvement in your classroom. Based on the "5E" model of learning, exploratories are designed to get your students excited about the…

This paper describes how a fourth grade class at a Canadian laboratory school used an approach to knowledge building that had students participating as intentional learners as they specialized in interest groups for their study of light. It examines how, later in the year, the goal of building collective knowledge became the focus for this group…

Discusses the history and evolution of measurement standards from 3000 BC to the modern metric system. Traces measurement techniques from comparisons with the human body to use of atomic clocks and lasers to establish the length of a meter. (JM)
