Traces electronegativity in four fundamental areas of chemistry during the period 1870-1910: (1) the relationship between electronegativity and classical valence; (2) the relationship between electronegativity and periodic law; (3) the relationship between electronegativity thermochemistry; and (4) the relationship between electronegativity and…

Presents the history of the Nobel Prize and explains the selection of nominees, who gets the award, and the notification process of the winners. (YDS)

Discusses the importance of complex molecular structures. Emphasizes their individual significance through examination of the Nobel Prizes of the 20th century. Highlights prizes awarded to Conrad Rontgen, Francis H.C. Crick, James D. Watson, Maurice H.F. Wilkins, and others. (SOE)

Describes the Nobel Chemistry prize and categorizes the number of laureates per field of chemistry, country, and age in the history of Nobel Prizes. Explains who receives the award and laureates' effect on chemistry. (YDS)

Introduces a lesson plan on astronomy and scientific research. Explains how astronomers conduct research and the detection methods they use. Provides demonstrations and ideas for students to build a giant model of the solar system. (YDS)

Presented is a descriptive account of Alessandro Volta's first notable success in 1775, the invention of a unique method of generating electricity. Luigi Galvani's announcement of his theory of "animal electricity" in 1972 is integrated into this interpretation of Volta's discoveries with electricity. Five experiments are described: (1)…

Author describes developments in understanding of tumor suppressor genes or antioncogenes that he feels is most important breakthrough in solving cancer problem. Describes 1969 starting work of Harris with mouse fibroblast genes and later work of Knudson with retinoblastoma cells. Provides evidence that deletion of chromosome that results in the…

Describes the organization and completion of a scientific field trip for a group of high school physics students that was organized primarily around a study of the Manhattan Project. The group visited the Trinity site, Los Alamos, several museums, and the National Radio Astronomy Observatory Very Large Array. Contact information for the various…

Describes six books appropriate for use with high school advanced or honors biology classes. The stories describe scientists who persevered against existing preconceptions in science or society at three levels: (1) prevailing mainstream scientific ideas; (2) gender; and (3) nationality or race. Presents ideas for using biographies as part of a…

This paper attempts to promote an understanding of physics through its history and replication of the oscillation experiments of Isaac Newton and Daniel Bernoulli from the 17th and 18th centuries. The experiments described can be treated at a level of sophistication to suit the interests and capabilities of the student. Reproductions in the…

Draws on an array of historical documents to delve into the history of genetics and the lives and scientific accomplishments of female geneticists that include Nettie Stevens, Rosalind Franklin, and Barbara McClintock. (Contains 20 references.) (Author/WRM)

Presented is a discussion of the events of the 20-year lapse between the invention of the pile in 1800 by Volta, and Hans Christian Oersted's famous definitive paper "Effects of a Current of Electricity on the Magnetic Needle." Students are thus enabled to appreciate the climate of the time and the manner and significance of Oersted's…

This paper focuses on the search for electromagnetic induction from 1820 to 1831 and the efforts by Augustin Fresnel's colleague, Andre Marie Ampere, in electric and magnetic induction. Faraday's work is discussed with excerpts from his diary on electromagnetism. A variety of different experiments by researchers including Francoise Jean Arago,…

This paper focuses on Michael Faraday's experimental research in electricity in the 1830's. Historical notes related to his work are included as well as experiments, his objectives, and illustrations of equipment for the experiments. Examples from his diary are given so that students can attempt to emulate his honest and systematic manner of…

This paper describes the events following the news of Oersted's discovery of the effects of a current of electricity on a magnetic needle. It focuses on Biot and Savart's law which expresses the force between a current element and a "molecule of magnetism" that can be deduced from Ampere's law of interaction between two current elements.…
