This series of experiments seeks to provide laboratory exercises which demonstrate concepts in Earth Science, particularly oceanology. Materials used in the experiments are easily obtainable. Examples of experiments include: (1) comparison of water hardness; (2) preparation of fresh water from sea water; (3) determination of water pressure; (4)…

This series of experiments seeks to provide laboratory exercises which demonstrate concepts in Earth Science, particularly meteorology. Materials used in the experiments are easily obtainable. Examples of experiments include: (1) making a thermometer; (2) air/space relationship; (3) weight of air; (4) barometers; (5) particulates; (6) evaporation;…

Described is the use of cleavage as an aid to microscopic determination of unknown minerals by immersion methods. Cleavages are examined in relation to fragment shapes, types of extinction, and cleavage-optical relationships. (Author/DS)

Presents a quantitative analysis of the "figure 8" found on the globes of most earth science textbooks, using an exercise of year's eccentric shadow plotting techniques. Indicates that the exercise can serve to change a student's abstract "figure 8" to his real learning experience. (CC)

Described is a project designed to transport a rich fossil-bearing bed of rock to the campus of a community college for analysis by undergraduate students. The arrangements, set-up acquisition of rock, transportation, and costs are discussed. The benefits of this arrangement are highlighted. (CW)

Develops an exercise in which students use magnetic-profile data gathered in the South Pacific to test the Vine-Matthews-Morley hypothesis. Uses the Eltanin 19N and 20N profiles. Relates the exercise to 20 current geology texts. (MVL)

Describes a "tracing the sun" worksheet combining models with computer programs and classroom discussion. Provides the worksheet including the nine steps of the activity and several discussion questions. (YP)

This book, addressed to students for their independent use as well as to teachers as a supplement to the standard texts, contains nearly 100 practical science experiments that cover a wide range of subjects at different grade and ability levels. It is designed to involve students in active scientific experimentation, demonstrations, and projects…

Three activities--"Earth's Orbit and the Four Seasons,""Observing Rabbits," and "Solutes, Solvents, and Solutions"--are described. Included in each are background information, a list of materials, key questions, teacher preparation, teacher introduction, procedure, and follow-up activities. (CW)
