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

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)

Described are concepts involved with the formation and actions of the Mid-Ocean Ridge. Sea-floor spreading, the magma supply model, discontinuities, off-axis structures, overlaps and deviation, and aquatic life are discussed. (CW)

Describes a simple activity designed to show the effects of leaching and evaporation on salts in the soil. (CP)

Reviews current ideas and research findings related to the flow patterns of mantle rocks. Highlights the components of the two-layer convection and whole-mantle models of mantle flow. Proposes that mantle flow is the key to understanding how the earth has cooled and chemically evolved. (ML)

Describes an activity that uses a simulation of glacial movement to stimulate middle school students' interest in geology. (JRH)

Describes a laboratory exercise using relief models, aerial photographs, topographic maps, and cone studies to determine depth and thickness of a concealed mineralized zone. (MA)

Presents seven topics suitable for a secondary level introduction to geochemistry. (SL)

Reports on the geology of a 60 square kilometer area located within the central Mt. Lofty Ranges with special references to teaching activities. (CP)

Advocates taking students on field trips to highway roadcuts to illustrate various geological principles. Photographs of three roadcuts (with sample objectives and questions/answers for students to answer) are included. Also included are suggestions for preparation, safety, and activities during such field trips. (DH)

This educator's guide discusses planetary geology. Exercises are grouped into five units: (1) introduction to geologic processes; (2) impact cratering activities; (3) planetary atmospheres; (4) planetary surfaces; and (5) geologic mapping. Suggested introductory exercises are noted at the beginning of each exercise. Each activity includes an…

Mount Jefferson State Natural Area is located in the southern Blue Ridge highlands of North Carolina and covers 489 acres, which includes peaks and upper slopes to the Mount Jefferson mountain. This document introduces students to the geology of Mount Jefferson State Park and focuses on the geologic processes and rocks and minerals of Mount…

Describes classroom science demonstrations and experiments that simulate the process of fossil formation. Lists materials, procedures and suggestions for successful activities. Includes ten student activities (coral fossils, leaf fossils, leaf scars, carbonization, etc.). Describes a fossil game in which students work in pairs. (CS)
