Presents a theoretical view of science which stresses ideas about the acquisition of complex knowledge that seem potentially useful for adaptation to teaching and learning science. Teaching strategies related to this theory of science development are presented. Bibliography. (LC)

Discusses an experiment for the measurement of the half-life of cosmic ray muons by using a single scintillator detector. (LS)

Discusses a strategy for presenting science concepts via activities which include personal, self-sensitizing frames of reference for students. Examples include force and temperature measurement. (JM)

Describes the scientific use of a board game to train the three-dimensional observation ability and to illustrate the concept of space symmetry. Included are four methods of interpreting results in terms of crystallographic lattices. (CC)

Describes how model rocketry can be a useful educational tool at the university level as a practical application of theoretical aerodynamic concepts and as a tool for students in experimental research. (BR)

Photographs of streakies were used to teach the concept of Rutherford scattering. Magnetic pucks with lights were used as streakies. (PS)

Describes a device designed to shoot rubber bands. Children investigate and measure forces, angles, distances and differences in materials used. (JM)

Described is an activity, designed for use with undergraduate elementary science students, which emphasizes certain concepts regarding the origin of measurement. (PEB)

Describes a classroom organized as a self-contained closed spaceship which provides an opportunity for individualized learning based on student interests and a chance to wrestle with the problems that would arise on an interstellar journey in a spaceship. (BR)
