Presented is a strategy which uses creationism and other pseudosciences as examples of non-scientific approaches to critical thinking to teach students the nature of science and the scientific method. Examples of the illogic of non-scientific approaches are given along with an explanation of how they can be used in teaching critical thinking to…

Describes a hands-on activity of contour mapping for grade nine students. Provides an extension activity and four references. Presents a laboratory activity sheet containing materials, responsibilities of group members, introduction, objectives, procedures, and questions. (YP)

Discussed are recognizing learning disabilities, the classification of learning disabilities, and testing instructional strategies in a geological sciences context. Suggestions for coping with the challenge of teaching these students are provided. Sources of assistance are listed. (CW)

Presented is an activity in which students construct a model of plate divergence with two sheets of paper to show the separation of two continental plates in a system of spreading ridges and faults. Diagrams and procedures are described. (CW)

Discussed are several phenomena associated with earthquakes. Included are seismic waves, plate movement, and earthquake measurement. Diagrams of different plate boundary types are included. An activity for teaching these events to elementary school children is provided. (CW)

Discusses the origin of the catastrophic event as to whether it was an episodic process or of extraterrestrial or endogenous origin. Develops a model of a volcanic mechanism to produce shocked quartz like those found in the Deccan basalts. (MVL)

Described are efforts to organize the research efforts concerning global change. Objectives include the development of long-term monitoring programs, global process research campaigns, and predictive computer models. (CW)

Discusses the development of a global program designed to provide a worldwide study of the earth, oceans, and atmosphere as a system; and to document changes that are occurring in this system. Explains the objectives and three core projects around which the experimental program has been organized. (RT)

Reviews discoveries and reports of dinosaurs to help put them into paleontological perspective. Proposes that discoveries not be announced from the field, but submitted to professional evaluation and peer review before release to the public. (Author/RT)

Describes a demonstration to show the character and behavior of mixing clouds. Discusses laminar and turbulent flow, and the formation of contrails and other cloud phenomena. (CW)

Described are one-atmosphere and compressed-gas technologies used for investigating the environment beneath the surface of the ocean. Suggestions for teaching this information to high school students are provided. (CW)

This article describes a teaching aid made from four colored foam balls mounted on a stiff wire circle used to teach about the changing seasons and earth temperature fluctuations. The spheres represent the Earth at the solstice and equinox positions. (MVL)

Examines what can be done to reintroduce content and process instruction from the earth sciences into the world's science curricula, especially at the secondary level. The earth system provides a conceptual theme as opposed to a disciplinary theme for organizing such integrated curricula, absent from prior efforts. (LZ)

Reports a study of the relationship between learning science content in an elementary science methods course with videodisk-based instruction and attitudes toward science teaching. The experimental group (n=42) learned science concepts through interactive videodisk lessons. Results showed the experimental group had greater gains in science…

Map making is described in the context of extraterrestrial areas. An analogy to terrestrial map making is used to provide some background. The status of projects designed to map extraterrestrial areas are discussed including problems unique to this science. (CW)
