Discusses the merits of science learning centers as a tool for teachers to encourage positive interaction among students of different backgrounds and ability levels. Describes the success of science centers through work with children and preservice teachers. (Author/KHR)

Reports two surveys conducted in 1983 and 1986 to determine physical chemistry textbooks being used. The selection processes and results are discussed. Provides six tables showing the results. (YP)

The illustration of molecular structures by means of stereo pairs (to project three-dimensional views of two-dimensional representations) has been common practice in periodicals, slide presentations, and books. Describes the stereo triptych and multiply rotated stereo views with diagrams and discusses the use of them. (YP)

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

Describes the scientific work of several women, including Marie Curie, Lise Meitner, Ida Noddack, Irene Curie, Marguerite Perey, Chien-Shiung Wu, and Maria Mayer. Discusses the connections between their discoveries. Thirty-six references are listed. (YP)

Describes the nature of a saturation curve and discusses several examples including the number of American scientists, population, Dow industrial index, and the national debt. (YP)

Discusses fluid mechanics for undergraduates including the differential Navier-Stokes equations, dimensional analysis and simplified dimensionless numbers, control volume principles, the Reynolds lubrication equation for confined and free surface flows, capillary pressure, and simplified perturbation techniques. Provides a vertical dip coating…

Asks whether the masses of a block of wood and a block of iron with the same weight are different. Discusses the buoyancy of air involved in the problem. (YP)

Presents a problem related to mass balances for checking the consistency of measured data from a process. Provides the solution to the problem with diagrams and calculation tables. (YP)

Describes the historic development of the periodic table from the four-element theory to the Lavoisier's table. Presents a table listing the old and new names of chemicals and the Lavoisier's table of elements. Lists two references. (YP)

Describes an alternate method of demonstrating thin film interference fringes with a laser by using a microscope slide glass cover. (MKR)

Describes the development of casts that replicate fossil finds to help teach human evolution. (MKR)

Visits to science museums can provide a complement to the science learning carried out in schools. However, science museums are informal learning environments where teachers usually have very little control over the ideas being implicated or the experiments that the students carry out. It is necessary to design educational materials for the visit…

This article describes three connected projects in physics: (1) a very successful course at the university level; (2) a collection of several thousand multimedia materials, its status and evaluation, and its dissemination; and (3) Web experiments--experiments that can be operated remotely from a distance via the Internet. (Contains 4 tables and 10…
