Describes how to make a superconducting pellet for classroom use. Details two tests that can use the pellet to demonstrate superconductivity. Discusses some of the mechanics and chemistry of superconductivity. Lists materiads and equipment necessary for these activities. (CW)

Discusses one mechanism proposed for the two-step initiation/promotion scenario of the development of cancer called oncogenes and a possible alternate mechanism that may prevent tumors from developing. Uses the example of retinoblastoma to illustrate the mechanisms. States that these mechanisms may not be caused by the activation of oncogenes. (CW)

Discusses the issue of mandatory genetic screening. Poses the question of the benefits, drawbacks, and motives involved. Provides a discussion activity to be used in high school biology classes consisting of a hypothetical situation and several questions. (CW)

Describes the purpose and possible uses of the new American Geological Institute/National Science Teachers Association Earth Science Examination. Provides an order blank for obtaining the test. Stresses that the test is specifically designed to test concepts and problem-solving ability. (CW)

Defines scientific theory. States that life science textbooks often misrepresent theory in their presentations. Presents an analysis of "Prentice Hall Life Science," a textbook adopted by several states including California, and two other popular texts. Criticizes these texts for equating myths, beliefs, legends, and theories, and their…

Shows how model rocketry can be included in physics curricula. Describes rocket construction, a rocket guide sheet, calculations and launch teams. Discusses the relationships of basic mechanics with rockets. (CW)

Discusses a unicellular component of hytoplankton that can easily be collected and studied in the classroom. Describes how to construct and use a diatometer. Suggests activities that can be done with diatoas collected outdoors or grown in an aquarium. (CW)

Reviews two computer software packages for use in physical science, physics, and chemistry classes. Includes "Physics of Model Rocketry" for Apple II, and "Black Box" for Apple II and IBM compatible computers. "Black Box" is designed to help students understand the concept of indirect evidence.
