Describes a Pascal-language based kinetics rate package for the microcomputer. Considers possible ecological uses for the program and illustrates results for several rate laws. Discusses hardware and software needs for adequate operation. (ML)

This article details two demonstrations involving color changes. Included are "Manganese Color Reactions" and "Flame Colors Demonstration." Include a list of materials needed, procedures, cautions, and results. (CW)

Critiques five arguments cited in support of process science. Considers the problematic nature of the processes and consequent difficulties encountered in mirroring these processes. Suggests an alternative way of viewing physics education through a trio of types of knowledge which can be used as governing principles in shaping education. (RT)

The Texas Academy of Mathematics and Science, a program of the University of North Texas, is a two-year, residential, early-admissions program for high-school juniors gifted in mathematics and science. Students attend university classes, live in a campus residence hall, and receive both a high-school diploma and college credits. (JDD)

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. 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. (CW)

Describes the practical workup of a multiple choice examination system in electrical engineering. Discusses some of the pedagogical advantages obtained by statistical handling of the data. Provides some examples of items. (TW)

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)
