Presents two methods for measuring the index of refraction of glass or lucite. These two methods, used in the freshman laboratory, are based on the fact that a ray of light inside a block will be refracted parallel to the surface. (HM)

Presents simple experiments to study the basic properties of light utilizing a flashlight, small mirrors, a magnifying lens, a plastic comb, paper and pencil, and a pair of eyeglasses. (JJK)

Provides a basic introduction to fluorescence enabling the amateur scientist to easily, and safely, demonstrate and photograph this phenomenon with the aid of an ultraviolet lamp. Includes a list of necessary equipment and materials, as well as catalog availability from several hardware suppliers. (JJK)

The different approaches to the generation of power from solar energy may be roughly divided into five categories: distributed collectors; central receivers; biomass; ocean thermal energy conversion; and photovoltaic devices. The first approach (distributed collectors) is the subject of this module. The material presented is designed to…

Stickybear's Science Fair: Light is a tool for teaching science skills using computer software. To enhance the use of software printed lesson plans are also provided including worksheets, labs, templates, and other materials needed to complete the activities. There are 12 lesson plans. Each of the lesson plans includes activities, an area focus, a…

This module is designed to give the learner an understanding of the nature of light and how its properties are used in the design of spectrophotometers. Problems promote the use of spectrophotometers in qualitative analysis, the optical elements used in a monochromator, and the physical properties of the prism and the diffraction grating. Other…

This high school physics resource is a simulator for optics, electronics, force, motion, and sound. Students can study oscillations, look at sound waves, and use probes to graph a wide variety of quantities. Over 100 activities are pre-written, and students can easily create their own additional activities using the multimedia editor. (WRM)

In preparing this volume, every effort has been made to ensure accuracy, the most recent authorities have been consulted, and it is believed that a faithful view is presented of the various sciences embraced, as far as they are at present developed. It is the intention of the author to keep his book up to the times by constant revision, and to…

Discusses the energy flux-density of two beams of light of equal energy that are intersected at a given angle. Examines an apparent contradiction to the physics law of conservation of energy known as Vavilov's paradox. (MDH)

This textbook presents scientific knowledge in a question-and-answer format. It is intended for the use of families and schools, explains about 2000 questions that children commonly ask, and is written in language so plain as to be understood by all. Heat, non-metallic elements, metals, organic chemistry, meteorology, optics, and sound are covered.

This textbook presents elementary principles of mechanics, hydrostatics, hydraulics, pneumatics, acoustics, pyronomics [sic], optics, electricity, galvanism, magnetism, electromagnetism, magneto-electricity, and astronomy. Among topics covered are descriptions and illustrations of McCormick's reaper, Sharps' Rifle, printing presses, House's…

This document--intended to help technology education teachers plan their classroom curriculum for secondary school and college students--contains units on exploring high-impact technology, microcomputers as technological tools, integrated manufacturing systems (the future of design and production), the role of robotics in integrated manufacturing…
