Compares group differences in strategy learning, use, and transfer to a more complex task for two groups of elementary students (N=48). Asked to perform three tasks in classifying igneous rocks, the groups differed in whether they received advice on the use of a specific strategy for performing each task. (CS)

To prevent increasing personal injuries and property loss, teachers need to educate themselves and their students about geological hazards. The author discusses earthquakes, downslope movement, dam failures, shoreline erosion, and other geologic hazards. Information on suggested teacher resources is provided. (DS)

Described is the annual Earth Science Teacher Day sponsored by the University of Texas. The purpose is to provide an attractive program combining both content enrichment and new classroom activities for earth science teachers. The format includes workshops, work sessions and field trips. (DS)

Summarized in chart form are data regarding published geologic maps for the 50 states and Puerto Rico. Information provided by state geologists includes scale, availability, and ordering instructions for both bedrock and surficial maps. (CS)

New findings about the planet, Saturn and its environs, as collected by Pioneer 11 are detailed. Topics discussed include: the composition of the planet's interior, the search for new satellites, and the planet's magnetic field. (BT)

Stereoscopic photo activities for students are described for the purpose of motivating students in earth science. Included also is the necessary equipment for obtaining the three-dimensional effect. (SA)

Described is a freshman science program at Deerfield Academy (Deerfield, Mass.) in meteorology, designed as the first part of a three-year unified science sequence. Merits of the course, in which particular emphasis is placed on observation skills and making predictions, are enumerated. (CS)

Described are ways in which urban "rocks" (building stones, curbstones, sidewalks, etc.) can be used as resources for earth science teachers. Discussed are such activities as: classifying buildings according to rock type and mineral composition, extrapolating geologic history by examining common building materials, economics of stone industry, and…

Teaching ideas are presented on the following topics: the number line, earthquakes and Venn diagrams, homework, and flow proofs in geometry. (MP)

The theory of plate tectonics is discussed as it relates to connection, purported to be the driving force involved in the movements of the earth's crust. (SA)

Focuses on recent research on currents and eddies of the earth's oceans. Special emphasis is given to instrumentation involved in studying the oceans. (SA)

Presents three activities that allow students to practice some of the techniques used by lunar researchers, and to become more familiar with lunar features through scrutiny of lunar photography. Topics include dimensions of a crater, different surface ages, and types of rilles. (Author/MA)

Presents an annotated bibliography of 12 publications dealing with remote sensing of the environment. Included is information on how to obtain aerial and spacecraft photographs and images. (BB)

Presents a classroom module designed to utilize Landsat imagery. Includes objectives, materials needed, procedures, and resource information for secondary teachers. (MA)
