Describes a geology laboratory exercise involving weathering and topographic maps which allows students to put knowledge to practical application. (SL)

Describes a demonstration experiment illustrating rotation of grains process of metamorphic rock formation utilizing clear gelatin blocks. (SL)

Describes an activity which incorporates topographic map interpretation, soils analysis, hydrogeology, and local geology in a five-week series of exercises for an introductory college earth science class. (CP)

Describes a college level introductory oceanography course that incorporates a hands-on laboratory component. The activities include the determination of density and buoyancy, light transmission in sea water, and wave refraction. (MA)

Describes laboratory exercises which demonstrate a new simplified technique for deforming thin samples of crystalline materials on the stage of a petrographic microscope. Discusses how this process allows students to see the development of microstructures resulting from cracking, slipping, thinning, and recrystallization. References and sources of…

Describes how mylonite samples can be used to determine the sense of shear. Several sample collection techniques are presented. Criteria for shear sense determination are outlined and discussed so that they can be recognized and interpreted by students familiar with the use of a compass and a petrographic microscope. (TW)

Describes the use of analysis of rotational faults in undergraduate structural geology laboratories to provide students with applications of both orthographic and stereographic techniques. A demonstration problem is described, and an orthographic/stereographic solution and a reproducible black model demonstration pattern are provided. (TW)
