Examines an earth-focus in social studies as a means of fostering better understanding of the physical environment. Presents evidence that this type of study will improve students' knowledge of the economic, historical, and social processes of the earth's inhabitants. (DB)

Investigated the development of children's concepts of the earth utilizing the Piagetian interview method to collect data from a sample of 240 children coming from grades four to eight of an experimental public school in Jerusalem, Israel. (HM)

Students at King Philip Junior High School run a rockshop as an alternative to the traditional study hall and science club. (BB)

Discusses the advantages and disadvantages of incorporating field projects into secondary level earth science courses. (SL)

Reviews requirements in developing crustal evolution modules suitable as supplementary classroom materials in grades 8-10 by the Crustal Evolution Education Project (CEEP). (SL)

Reproduces the Crustal Evolution Education Project (CEEP) instructional module dealing with concepts of magnetic polarity and polarity reversal. Included are materials needed, teacher guides, procedures, and objectives for three activities. (SL)

Describes a computer program which enables students to carry out a simulated three stage mineral exploration program. (SL)

Examined are the results of three studies completed at the University of Northern Iowa on the status of earth science teaching in Iowa over a ten-year span and the characteristics of exemplary teachers. Considered are course offerings, teacher backgrounds and preparation, instructional materials, and laboratory and activity time. (CW)

Presented is a description of a BASIC program to be used on an IBM microcomputer for calculating and plotting synthetic seismic-reflection traces for multilayered earth models. Discusses finding raypaths for given source-receiver offsets using the "shooting method" and calculating the corresponding travel times. (Author/CW)

Describes the very-long-baseline array (VLBA) system of radio telescopes that will be completed in the early 1990s. Explains how the VLBA system works and the advantages over present technology. Compares associated international telescopes and very-long-baseline interferometers (VLBI). Illustrates applications for the VLBA and VLBI. (CW)

Discusses the use of remote sensing from satellites to monitor glaciers. Discusses efforts to use remote sensing satellites of the Landsat series for examining the global distribution, mass, balance, movements, and dynamics of the world's glaciers. Includes several Landsat images of various glaciers. (TW)

Highlights the views and comments of Commander Dick Scobee of the space shuttle Challenger, and his wife on various aspects of the space mission. Provides responses to questions involving the goals, values, and tasks of the crew and of the total space shuttle program. (ML)

Outlined is a two week unit on weather offered as independent study for sixth- and seventh-year students in Vancouver, Canada, schools. Included is a section on weather lore and a chart of weather symbols. (SL)
