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 guide offers a systematic approach to the wide variety of published biographical information on men and women of science in the life, earth and physical sciences, primarily from 1989 to 2006, and complements Library of Congress Science Tracer Bullet "TB88-3" ("Biographical Sources in the Sciences," compiled 1988 [ED306074]) and "TB06-7"…

Discusses magnetic polarity stratigraphy as a tool for correlation of fossiliferous terrestrial deposits. Explains the strengths, weaknesses, limitations, preferred conditions, sampling, laboratory analysis, and applications of this technique. A table of paleomagnetic studies on vertebrate-bearing terrestrial sections arranged by age and locality…

Discusses the origin of the catastrophic event as to whether it was an episodic process or of extraterrestrial or endogenous origin. Develops a model of a volcanic mechanism to produce shocked quartz like those found in the Deccan basalts. (MVL)

The purpose of this guide is to highlight some broad areas in which teachers and other adults have exceptional opportunities to encourage and enjoy teaching children science. Each area in the book provides some hands-on ideas for projects as well as an annotated list of readily available resources that might prove helpful on the topic at hand. The…

Highlights scientific accomplishments in 1981. Focuses on space sciences, medicine, geology, chemistry, physics, zoology, paleontology, environmental problems, and genetics including such topics as the Space Shuttle, Mount St. Helen's endangered species, genetic engineering, and the scientists associated with these accomplishments. (JN)

Highlights advances/discoveries (and scientists responsible for them) in various science areas during 1983: space science (shuttle flights, Russia); astronomy (infrared satellite, inflationary universe); physics (W/Z particles); chemistry (carbon bonding); environment (acid rain, dioxins, El Nino); bioscience (chemical signals); paleontology…

The purpose of this curriculum guide is to help teachers implement the Alabama Course of Study: Science. The major emphasis of the guide is to provide student-oriented, hands-on activities that engage students in "sciencing" behaviors. This guide has two major components, the table of contents and the activities. The table of contents…

Describes "Einstein's Adventurarium," a science center housed in an empty shopping mall in Gillette, Wyoming, created through school, business, and city-county government partnership. Describes how interactive exhibits allow exploration of life sciences, physics, and paleontology. (KDFB)
