Discusses the application of the laws of physics to natural phenomena, including Jackrabbit ears, transparent atmosphere, formation of ice, and long-wave radiation. (YP)

Discussed is misinformation people have on the subject of radiation. The importance of comparing artificial source levels of radiation to natural levels is emphasized. Measurements of radioactivity, its consequences, and comparisons between the risks induced by radiation in the environment and from artificial sources are included. (KR)

Sunlight (solar radiation) provides many beneficial contributions to mankind, including warmth and energy, vision and photoresponses, photosynthesis, and vitamin D synthesis. Along with these positive benefits attributed to solar radiation, there are also adverse effects. A particular adverse effect of current interest and concern which is…

Summarizes the development of the Earth's age calculation including the work of Archbishop Ussher, James Hutton, Lord Kelvin, Ernest Rutherford, Bertram Boltwood, and Arthur Holmes. Describes the changes in radioisotope dating methods. (YP)

This document presents a course in the science of nuclear energy, units of which may be included in high school physics, chemistry, and biology classes. It is intended for the use of teachers whose students have already completed algebra and chemistry or physics. Included in this paper are the objectives of this course, a course outline, a…

This publication contains statewide standards for the radiologic technology program in Georgia. The standards are divided into 12 categories; Foundations (philosophy, purpose, goals, program objectives, availability, evaluation); Admissions (admission requirements, provisional admission requirements, recruitment, evaluation and planning); Program…

Environmental educators are worried about the ultimate ecological threat--nuclear war, which could burn thousands of square miles, sterilize the soil, destroy 70 percent of the ozone layer letting in lethal ultraviolet rays, and cause severe radiation sickness. Educators must inform themselves, teach others, contact government representatives, and…

This document presents the process of radon diagnostics and mitigation in schools to help educators determine the best way to reduce elevated radon levels found in a school. The guidebook is designed to guide school leaders through the process of measuring radon levels, selecting the best mitigation strategy, and directing the efforts of a…

This guide presents the standard curriculum for technical institutes in Georgia. The curriculum addresses the minimum competencies for a radiologic technology program. The guide contains four major sections. The General Information section contains an introduction giving an overview and defining purpose and objectives; a program description,…

Heavily ionizing charged particles produce radiation damage tracks in a wide variety of insulating materials. The experimental properties of these tracks and track recorders are described. The mechanisms by which the tracks are produced are discussed. (Author/KR)

Schools may be a significant source of radon exposure for children and staff. Describes radon detection kits and technologies, when to use them, and what action to take given the results of a radon test. (MLF)

Attempts to clear up misunderstandings about radon and outlines information teachers can convey to their students. Includes a brief history of radon, health threats posed by radon, methods to measure radon quantities, homeowner risks and preventative actions, and a glossary of radon terms. (MDH)

Describes a genetics activity illustrating genetic variation, mutation, and influence of environmental factors on genotypic expression. Irridiated bean seeds are planted and observed (x-rayed by dentist's x-ray machine at different exposures and for different times). Questions to extend the activity are discussed. (Author/JN)

The effect of sunlight on skin is described. Topics of discussion include the ozone layer, photosynthesis of vitamin D, tanning, the immune system, skin cancers, moles, prevention, sunscreens, effect of diet, vitamins C and E, the retinoids, carotenoids, and vaccines. Activities are provided. (KR)

A rationale is presented for the use of inquiry activities in the biology classroom when teaching the concept of evolution. An annotated list of evolution laboratory activities from 18 nontextbook sources is included. Each annotation includes the title, source, major evolutionary concepts, and a brief description. (KR)
