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

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)

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

Two instruments are described which were designed to provide beginning students with the tools for determining sun-time and the altitude of the sun. Both can be constructed by the student. A simple-to-construct scale is included. Activities are suggested to use with the instruments. (Author/EB)

Describes an introductory course in geology for nonscience majors that involves students in laboratory exercises related to rock classification. (GS)

In this exercise, students examine Aristotle's weight hypothesis by testing variously shaped marble chips. These chips are weighed and dropped down a water tube. Average fall times and weights are recorded and graphed. Students are asked to apply this information to rock and soil deposition by streams. (MA)

Describes an earth science laboratory approach designed to involve students in an ongoing method of solving problems; student questions and discussion provide the basis for laboratory exercises. (Author/SL)

Describes activities for secondary earth science and biology classes in collecting, preparing, mounting, and manipulating microfossils. (SL)

Describes an eighth grade rock exchange project in which small groups of students researched, then wrote letters to schools throughout the United States requesting samples of local rocks and minerals. Provides experience in use of the atlas and letter writing. (CS)

Uses a vortex device as a model to study low-pressure systems and other related investigations. (LS)

Explains the arrangement of materials in a classroom to simulate land or weather conditions. On each desk in the room pertinent bits of information are placed. Students gather bits of information and synthesize material into an overall map of the area. (CP)

Presents abstracts of innovative activities of students in grades 7 through 12. Projects include community surveys, student or teacher initiated home/school experiments, scientist-supervised research by high school students, community and school service projects. (EB)

Describes procedures that can help students to make model geodes from eggshells, copper sulfate, and other crystalforming substances. (HM)
