Though central to any pedagogical development of physics, the concept of mass is still not well understood. Properly defining mass has proven to be far more daunting than contemporary textbooks would have us believe. And yet today the origin of mass is one of the most aggressively pursued areas of research in all of physics. Much of the excitement…

Various phenomena in chemistry and biology can be understood through Gibbs energy utilization. Some common phenomena in chemistry are explained including neutralization, hydrolysis, oxidation and reaction, simultaneous dissociation equilibrium of two weak acids, and common ion effect on solubility.

Activities involving concave rubber disks are utilized to illustrate the scientific principles of kinetic and potential energy. Provides teacher instructions and questions related to the activity. (MDH)

Presents an experiment to show the energy conservation principle using a bow. Describes how to measure the force and work of the bow and the initial velocity of an arrow. (YP)

Presented are a list of topics and references for a course in which scientific theories and concepts are developed to explain the energy crisis. Using the suggested approach, students gain an understanding of scientific theories and concepts as they relate to current human problems. (DS)

Reviews the problem of certain logical and conceptual shortcomings in textbook presentations of the energy concepts in introductory physics. Discusses concepts and principles related to thermodynamics and echanics. Provides many formulas and diagrams. (YP)

Discussed is the idea that models should be taught by emphasizing limitations rather than focusing on their generality. Two examples of gas behavior models are included--the kinetic and static models. (KR)

Discusses the early recognition of chaos as seen in Poincar's work solving dynamical problems. Proposes five examples from which an inventory of the manifestation of chaos can be inferred. Discusses some instructional consequences of the development of ideas of chaos. (MDH)

This guide provides an introduction to the major issues and literature of science in society. The book is divided into four parts: (1) "The Nature of Science"; (2) "The Nature of Technology"; (3) "Humans in the Environment"; and (4) "Current Issues in Science." The first part covers a history of science technology are covered in the second. In the…
