Included are instructional materials designed for use with disadvantaged students who have a limited reading ability and poor command of English. The guide is the first volume of a two volume, one year program in earth science, and contains these four units and activities: Earth Materials, 8 activities; Weather, 10 activities; Water, 4 activities;…

Included are instructional materials designed for use with disadvantaged students who have a limited reading ability and poor command of English. The guide is the second volume of a two volume, one year program in earth science, and contains these five units and activities: Rock Cycle, 12 activities; Minerals and Crystals, 6 activities; Weathering…

Provides background material and laboratory procedures for an activity which requires students to compare (in quantitative terms) fossils from 10 localities and to objectively define provinces, regions, and realms. These paleobiogeographic relationships are then used to reconstruct the drift histories of the three continents on which the 10…

Suggests methods of teaching principles of geological inference by observation of sidewalks, parking lots, school grounds, and vacant lots. (AL)

The purpose of this study was to design a beginning course in geology which not only accents the sociological implications inherent in the study of geology, but also presents the learner with the opportunity to solve geological problems by using laboratory techniques. A curriculum rationale was designed in which those environmental problems with…

Describes techniques for studying hand specimens of polished rock slabs. (SL)

Discusses the structure and formation of snow crystals, outlines the history of snow removal, and describes techniques that can be used by students for studying snowflakes and relating their structure to the conditions under which they were formed. (JR)

Describes exercises in which tabs from aluminum beverage cans are used to introduce principles of classification, biostratigraphy, and evolution. Provides diagrams which represent dorsal and ventral views of species and a table which graphs units of time in relation to species duration. (RT)

A gas pressure gauge has been constructed for use in a student experiment involving the law of atmospheres. From pressure data obtained at selected elevations the average mass of air molecules is determined and compared to that calculated from the molecular weights and percentages of constituents to the air. (Author/BB)

Describes student activities with mercuric oxide and mercury that help them to form models of the solar system and its creation. (JR)

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

The design and data management of an activity to study weathering by increasing the rate of mineral dissolution in a microwave oven is described. Data analysis in terms of parabolic and first-order kinetics is discussed. (CW)
