Describes an educational program that asks students to attempt to prove that the earth is spherical and that it rotates. Presents tips to pique student interest and charts related to sensing the spin, nonrotation notions, flat earth fallacies, evidence that the earth is spherical and rotates, and the role of watersheds in proving that the earth…

Describes an activity that helps students see how a paper map can represent a three dimensional object by having students build a realistic model that clearly shows what a contour line is and why it behaves the way it does. (DDR)

Synthesizes the results of three case studies of middle school classrooms in which computer and video materials were used to teach topics in earth and space sciences through interactive simulations. Describes specific instances in which common current practice is problematic. Makes suggestions regarding improved design principles for such…

Describes the Slanting Leaf Beds Project in Oregon in which fifth and sixth graders participated in hands-on, long-term research projects designed to provide students with an understanding of scientific processes and concepts. Students first worked in pairs obtaining samples and making tentative identifications. Group data was pooled and compared…

Presents the Nevada Science Teacher Enhancement Project (N-STEP) in which 50 high school teachers worked with research scientists, educational faculty, and high school students on authentic, field-based research projects in the geosciences, biological sciences, or social sciences. Indicates improved satisfaction of teachers and students with their…

Discussed are the importance of earth science, how earth science should be taught, and when and to whom earth science should be taught. Topics which should be taught in a modern earth science course are suggested. (CW)

Presented are the reasons why the earth sciences must play a major role in curriculum renovation. Philosophical, methodological, and conceptual contributions to K-12 curriculum content are discussed. (KR)

Presented are interdisciplinary activities that help students to identify minerals and to begin to understand the properties that make each one unique. The concept of individuality is emphasized. Included is a section on minerals and an explanation of their physical characteristics. (KR)

Presented is a lesson designed to demonstrate the concept of telepresence to students. Provided are objectives, teacher preparation, procedures, and a sample debris field grid. (CW)

Described is a project designed to transport a rich fossil-bearing bed of rock to the campus of a community college for analysis by undergraduate students. The arrangements, set-up acquisition of rock, transportation, and costs are discussed. The benefits of this arrangement are highlighted. (CW)

Presented are the background theory, program procedures, output display, and applications for this program which is designed to calculate the slip vector and the stress to normal stress ratio on an arbitrarily oriented fault plane. Program availability is discussed. Twelve references are listed. (CW)

Discussed is a geology education program which includes hikes, lectures, naturalist training sessions, workshops, writing, collecting, upgrading park facilities, and producing exhibits in state parks in the Lake Michigan District of Wisconsin. The importance of public education and sources of public information are stressed. (CW)

Described is a two-course sequence dealing with the origin and evolution of the entire natural system including the universe, solar system, earth, and life. The content, suggestions about teacher preparation, teaching techniques, and testing are discussed. (CW)

Describes a laboratory exercise testing the Vine-Matthews-Morley hypothesis of plate tectonics. Includes 14 questions with explanations using graphs and charts. Provides a historical account of the current plate tectonic and magnetic anomaly theory. (MVL)

Proposed is a three course sequence for all college students designed to raise the level of undergraduate scientific literacy. The rationale, topics to be covered, and an outline of an earth-systems course are presented. Problems in the implementation of such a sequence are discussed. (CW)
