Addresses the requirements of high school students and noncrystallographers in lectures on crystals, diffraction, and structure analysis. Discusses basic understanding and a sequence that addresses these requirements. Suggests visual and descriptive teaching methods used in this effort. (CW)

Describes a crystallography experiment using both diffraction-angle and diffraction-intensity information to determine the lattice constant and a lattice independent molecular parameter, while still employing standard X-ray powder diffraction techniques. Details the method, experimental details, and analysis for this activity. (CW)

Provides a framework of the disciplines of materials science and engineering as they have developed. Discusses the philosophy, content, and approach to teaching these courses. Indicates the range of crystallographic topics contained in the materials science and engineering curriculum at the Massachussetts Institute of Technology. (CW)

Overviews the "Nuffield Coordinated Sciences" program. Discusses the aim, coordination of content, presentation, and the writing timetable. (YP)

Discusses a course proposal which concentrates on fewer topics and covering the topics in greater depth. Proposes a sequence in which each topic is introduced phenomenologically, the theory is developed, and the applications are discussed. Uses optics as an example. Lists some disadvantages and advantages of the proposed topical organization. (YP)

Describes a laboratory demonstration that illustrates principles of miscible displacement and chemical retardation in soils. Discusses how the experimental apparatus can be constructed from readily available materials. (TW)

Reviews two computer software packages for use in physical science, physics, and chemistry classes.

Presented is a classification of polymers according to physical condition. Considered are molecular structure and arrangements. Described are demonstrations using polarized light and the mechanical properties of polymers. (CW)

Provides an annotated list of references on computer-oriented projects. Includes information on computers; hands-on versus simulations; games; instruction; students' attitudes and learning styles; artificial intelligence; tutoring; and application of spreadsheets. (RT)

Describes an activity designed to help children understand why there is a limit to the size of animals that live on land. Details the materials and set-up for this activity. Contains a reproducible, three-part activity sheet to accompany the activity. A key for the teacher is included. (CW)

Presents guidelines for creating student database files that supplement classroom teaching. Highlights include determining educational objectives, planning the database with computer specialists and subject area specialists, data entry, and creating student worksheets. Specific examples concerning elements of the periodic table and…

Stresses the importance of hands-on science in elementary schools. Gives tips on designing your own excellent science program. Lists resources for hands-on activities. (RT)

States that students who simultaneously acquire subject matter concepts and high-level thinking skills are more likely to learn, remember, and be able to apply the concepts. Provides an example for assisting faculty in developing better decision-makers. (RT)

Discusses some of the drawbacks of using a demonstration of the electrolysis of water to illustrate the interconversion between electrical and chemical energy. Illustrates a simple apparatus allowing demonstration of this concept while overcoming these drawbacks. (CW)
