The application of technology in classroom settings has equipped educators with innovative tools and techniques for effective teaching practice. Integrating digital technologies at the elementary and secondary levels helps to enrich the students' learning experience and maximize competency in the areas of science, technology, engineering, and…

Presented are activities for students in grades 3-6 which use assorted breads and spreads to represent layers of the earth's crust. It is suggested that in addition to providing good nutrition, this method has helped the children use the processes of science to deduce some basic principles of geology. (KC)

Describes how the Hubble Space Telescope works and how scientists repaired the spherical aberration that caused a reduction in image quality. (ZWH)

Article described an experiment in which students learned to investigate the sound of water particles falling over rocks as well as the change in composition of rocks as they travel along the riverbed. (RK)

Describes seasonal activities that can be used to study the sedimentation process. (ZWH)

Presents three lapidary activities which have been developed to teach enrichment courses to adults and young people. Described are activities and materials for polishing and shaping rocks. (EB)

Describes a project that predicts the orbits of satellites using a TI-85 calculator. Enables students to achieve a richer understanding of longitude, latitude, time zones, orbital mechanics of satellites, and the terms associated with satellite tracking. (JRH)

Describes an activity that uses a simple classroom experiment to measure the amount of carbon dioxide in air samples. (ZWH)

This booklet gives a history of human observations of Mars, including observations made from U.S. unmanned spacecraft. Also included is a discussion, "Encountering a New World: How to Explore a Planet," which contains classroom discussion questions and four classroom activities. The classroom activities include: (1) How to explore a…

The Maryland Pilot Earth Science and Technology Education Network (MAPS-NET) project was sponsored by the National Aeronautics and Space Administration (NASA) to enrich teacher preparation and classroom learning in the area of Earth system science. This publication includes a teacher's guide that replicates material taught during a graduate-level…

Presents a brief description, including dates and estimated time of appearance, of a total eclipse of the moon. Suggested details for observing, requiring little or no experience or equipment, are presented. (EB)

Describes the characteristics of rare earth elements. Details the physical chemistry of rare earths. Reviews the history of rare earth chemistry and mineralogy. Discusses the mineralogy and crystallography of the formation of rare earth laden minerals found in the earth's crust. Characterizes the geologic history of rare earth elements. (CW)

Traces the historical events that linked geology with the planetary sciences. Reviews the origins of meteorities as a modern science and highlights the advances made in this area. Discusses lunar related theories and research. (ML)

Provides background information and references on Comet Halley (which will be observable by telescope in October 1985 and reach its most brilliant appearance in March and April of 1986). Suggestions for equipment and maps of its path through the sky are included. (DH)

Discusses the nature and effects of the El Nino/Southern Oscillation phenomenon. Indicates that new understanding of the phenomenon from current data will provide a global view of climate that has never before been within reach. (JN)
