Surveys careers in working with animals and gives suggestions for use of this topic in the classroom. Activities involve identifying reasons for choosing any career, careers involving animals (traditional and nontraditional), community personnel, and pros and cons of animal careers. Two student activity sheets are included for duplicating. (DH)

This short article consists of some thoughts derived from a longer paper (Palmer, 1992), together with some more recent ideas. I became interested in buckminsterfullerene (Buckyballs) as a result of an E-Mail discussion of the topic in 1991. The chemistry of buckyballs is now evolving very rapidly and is gradually creeping into school…

In August, 1981, National Aeronautics and Space Administration launched Dynamics Explorer 1 into polar orbit equipped with three cameras built to view the Northern Lights. The cameras can photograph aurora borealis' faint light without being blinded by the earth's bright dayside. Photographs taken by the satellite are provided. (JN)

This article reports the adoption of new policies to restrict experiments on animals in the elementary or secondary school classroom. The controversy involving animal welfare groups is discussed as it relates to animal abuse by students. (SA)

In-service training of elementary school science teachers, the topic of the United States-Japan Joint Science Seminar held in Kyoto and Tokyo, Japan in 1975, is presented. Program innovations and their relationship to in-service education in the United States and Japan are discussed. The role of Japanese science centers and schools is included in…

Presents a rationale for the new Soviet biology curriculum. Explains guidelines for teaching methodology. Describes in some detail the goals and tasks for students in the new Soviet biology curriculum for grades six through eleven. (RKM)

Described is the teaching of technology in British secondary schools. Some of the types of technology courses are described and issues and trends related to the teaching of technology are considered. (RH)

Discusses projects entered in the 46th Annual Science Talent Search and identifies the 40 successful competitors. Includes a listing of the winners by state and also names the student's school and city. (ML)

Offers perspectives on natural selection and the phenomenon of altruism. Presents evidence for and against the theories that evolution acts essentially on genes, on individuals, on kin, or on larger groups. (ML)

Discusses the development of the concept of atomicity and some of the many which can be used to establish its validity. Chemical evidence, evidence from crystals, Faraday's law of electrolysis, and Avogadro's number are among the areas which show how the concept originally developed from a purely philosophical idea. (JN)

Describes the nature of gradient refractive index (GRIN) lenses, focusing on refraction in these materials, focal length of a thin Wood lens, and on manufacturing of such lenses. Indicates that GRIN lenses of small cross section are in limited production with applications suggested for optical communication and photocopying fields. (JN)

Continental crust underlies the continents, their margins, and also small shallow regions in oceans. The nature of the crust (much older than oceanic crust) and its dynamics are discussed. Research related to and effects of tectonics, volcanism, erosion, and sedimentation on the crust are considered. (JN)

The chemistry of the ocean, whose constituents interact with those of air and land to support life and influence climate, is known to have undergone changes since the last glacial epoch. Changes in dissolved oxygen, calcium ions, phosphate, carbon dioxide, carbonate ions, and bicarbonate ions are discussed. (JN)

The absence of "hands-on" experiences with science equipment in schools stimulated the production of science kits for children. Thirty years later this enterprise has become a national institution in Brazil with a proud history of effecting change in the teaching of science throughout this country. (Author/JN)

Discusses a 20-year period in British geology (1820-1840), focusing on a theory proposed by Reverend William Buckland in his "reliquiae diluvianae of Relics of the Flood." Indicates that this flood theory, the centerpiece of modern creationism, was disproved by professional clergymen who were also geologists, scientists, and…
