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)

This packet contains a series of teaching guides on land and people. This series features lessons on Cape Cod, the Everglades, and Los Angeles. Each section is divided into two parts: "For the Student" and "For the Teacher." The student materials give students a focus question to answer and also provide them with information…

The author proposes the inclusion of earth science curricula into the elementary school program because of the inherent interest nature has for young children. Some activities are described. (CP)

Provides a format for the identification of fossils when introducing geologic time in the laboratory. Presents an organization of fossils into three major groups based on radial, bilateral, and no apparent symmetry. States that this method reinforces student learning and provides for an orderly approach to fossils. (RT)

Two easy student activities that demonstrate physical weathering by expansion are described. The first demonstrates ice wedging and the second root wedging. A list of the needed materials, procedure, and observations are included. (KR)

Simulated environments eliminate distracting details, thus making possible a careful attention to particular systems and concepts. (MJB)

This packet contains a series of teaching guides on global change. The series includes lessons on dendrochronology; land, air, and water; and island living. Included is information such as : laws of straws; where land, air, and water meet; and Earth as home. Each section provides an introductory description of the activity, the purpose of the…

Summarizes some of the astronomy materials developed at the Lower North South Australian Science Teachers Association (SASTA) meeting of October, 1978. (HM)

Asserts that the theme of movement in physical geography is important but difficult to convey to students. Contends that repeat photography, portraying movement of physical features on the landscape through the seasons of a year, is a valuable instructional method. (CFR)

Describes types of meteors and micrometeorites that enter the Earth's atmosphere. Presents an activity where students collect micrometeorites with a strip of tape in an undisturbed outdoor area. After 24 hours, they examine the tape by sandwiching it between 2 glass slides and view through a microscope at 100X. (PR)

This resource guide was developed for elementary, middle, and high school teachers to teach about oceanography and coastal processes. This guide contains information on the program's history and names and contact information for all Operation Pathfinder participants since 1993. The body is divided into 6 topics. Topic 1 is on Physical Parameters,…

These activities are designed to teach about the sediments of Hudson Canyon. Students investigate and analyze the patterns of sedimentation in the Hudson Canyon, observe how heavier particles sink faster than finer particles, and learn that submarine landslides are avalanches of sediment in deep ocean canyons. The activity provides learning…

Presents two exercises in astronomy: (1) the production of star trails and (2) the measurement of the distance between stars and their apparent movement in the sky. Includes directions, illustrations, and activity questions. (MA)

Describes activities that take advantage of heavy snowfalls to study numerous geological concepts including sedimentation, precipitation, morphology and metamorphosis of crystals, compaction and cementation, fossilization, and erosion. (JRH)

Discusses activities to investigate rock art in science courses. (MKR)
