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)

Reported is a method of producing artificial lightning in an ordinary clear lightbulb. The appearance of sparks produced is that of a miniature stroke of forked lightning seen in natural thunderstorms. The sparks also show the intricate branching patterns often seen in natural lightning. (JT)

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)

Article described an experiment in which students learned to investigate the sound of water particles falling over rocks as well as the change in composition of rocks as they travel along the riverbed. (RK)

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)

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…

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

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

Describes activities by which the porosity and permeability of materials with respect to water can be measured. (CP)

Presents five hands-on activities that allow students to detect, measure, reduce, and eliminate moisture. Students make a humidity detector and a hygrometer, examine the effects of moisture on different substances, calculate the percent of water in a given food, and examine the absorption potential of different desiccants. (MDH)

While rocks and minerals are often regarded as among the most static and solid objects, the body of knowledge of which they are part is always changing. This teachers guide contains activities and experiments designed to enhance students understanding of geology and petrology. By examining actual specimens of the Earth's crust, students learn…

Investigates the nature of catastrophic volcanism and the rifting process. Describes two kinds of evidence: quantitative descriptions of rock melting and a wide range of observations. Discusses examples of continent growth in the North Atlantic, India and the Seychelles islands, and the South Atlantic. (YP)
