Discusses a number of significant persons and ideas in the European development of notions relating to faunal succession. Major focus is on the 17th through the 19th centuries, from the onset of rational investigations of the earth to definition of the stratigraphic zone. (JN)

Discusses how early notions about celestial mechanics were restructured, one by one, involving the following concepts: the celestial sphere and its rotation; the spherical earth; planetary motion; and models for the solar system initiated by Eudoxus, Hipparchus, Ptolemy, and Copernicus. (JJK)

Explored are the following dimensions of scientific literacy: the ethos of modern science and the cumulative achievements of science and technology in the history of the United States and in the nature of contemporary society. Also discussed is the reform movement in science education. (KR)

Points out that large earthquakes can take place not only on faults that cut the earth's surface but also on blind faults under folded terrain. Describes four examples of fold earthquakes. Discusses the fold earthquakes using several diagrams and pictures. (YP)

Provides a historical account of some of the explanations that were posed to describe the behavior of gases. Emphases are placed on gas theories presented by John Dalton. (ZWH)

One dilemma of constructivist modes of instruction, which involve engaging students in discussions concerning a range of possible explanations for a given phenomenon, is that such an approach may confuse students who believe that absolute scientific truth exists. Historical dialogues in which various perspectives are aired by key scientists of the…

Discusses the meaning of velocity in the Lorentz force law and to what the velocity of the charge is relative. Provides a brief summary of the history of the magnetic force. (23 references) (MDH)

Explains how the Punnett Square method received its name. Describes the studies of Bateson and Punnett that provided the first clear example of linked genes. (PR)

Strong European roots shape the view of science history as presented in science textbooks, presenting few women and minority role models. Presents examples of scientific discoveries made by minorities. Asserts that the contributions of culturally diverse individuals and women should be part of the science curriculum. (MDH)

Incorporates some ideas from a book by Galileo into a problem-solving format that challenges students. (LS)

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)

Discusses how Volta's concept of electromotive force seems to be forgotten. A comparison of the concepts of potential difference and electromotive force is also included. (HM)

Discusses the change in pressure as a balloon expands. Describes the pressure change in a spherical soap bubble and a rubber membrane on the tube. Provides demonstrations when two balloons are connected by a tube. Lists five further reading materials. (YP)

The twentieth century has witnessed a burst of discovery in physics unparalleled in human history. Despite the fact that general relativity and quantum mechanics are well over half a century old, introductory physics classes in high schools, colleges, and universities essentially ignore them. These two seminal ideas, the phenomena of…

Describes the discovery and characteristics of superconductors. Discusses some experiments on the levitation of a magnet over a superconductor. (YP)
