The objective of our program is to foster and facilitate authentic research experiences in middle and high school science courses. We do so by providing students with a complete experience in scientific experimentation and communication. The centerpiece is a set of experiment modules in which students investigate the effects of toxic chemicals on…

Presents data on release of renin during direct and indirect stimulation of renal nerves. Conclusions show that renin release is influenced by change in activity of carotid and cardiopulmonary baroreceptor systems, and excitation of discrete areas of brain and hypothalamus by changes in renal sympathetic nerve.

With the use of graphs, the phenomenon of deep ocean water mixing is discussed. Research methodologies and findings are detailed. (CP)

Analyzes the distributions of particles and particle flux in the Atlantic Ocean. (CP)

Discusses the origin and existence of sediment layers in the Atlantic Ocean. (CP)

The mixing of sediments by organisms (bioturbation) is discussed. Research techniques are discussed and data on Atlantic bioturbation rates are provided. (CP)

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 theory and application of an atomic fountain which pushes the atoms by laser pulses. Discusses the applications in measuring atomic properties and in building an atomic clock. (YP)

Outlines the Cosmic Background Explorer (COBE) mission to measure celestial radiation. Describes the instruments used and experiments involving differential microwave radiometers, and a far infrared absolute spectrophotometer. (YP)

Investigates the nature of catastrophic volcanism and the rifting process. Describes two kinds of evidence: quantitative descriptions of rock melting and a wide range of observations. Discusses examples of continent growth in the North Atlantic, India and the Seychelles islands, and the South Atlantic. (YP)

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

Investigates memory storage and molecular nature of associative-memory formation by analyzing Pavlovian conditioning in marine snails and rabbits. Presented is the design of a computer-based memory system (neural networks) using the rules acquired in the investigation. Reports that the artificial network recognized patterns well. (YP)
