Boyer, Robert E. – 1971
Highlighted are the effects of weathering through field investigations of the environment, both natural rocks, and the urban environment's pavements, buildings, and cemeteries. Both physical weathering and chemical weathering are discussed. Questions are presented for post-field trip discussion. References and a glossary are provided. (Author/RE)

Rapp, George, Jr. – 1971
The causes for many of the colors exhibited by minerals are presented to students. Several theories of modern physics are introduced. The nature of light, the manner in which light interacts with matter, atomic theory, and crystal structure are all discussed in relation to the origin of color in minerals. Included are color pictures of many…

Verduin, Jacob – 1971
Attention is directed to processes going on in lakes which are not apparent to the observer of their scenic beauty. Explored are the lifetime of lakes, how lakes are formed, elements of a field trip to a lake, and influence of human activities on lakes. Sample post-field trip questions, references, and a glossary of terms are also included. (RE)

Foth, Henry; Jacobs, Hyde S. – 1971
Discussed are the importance of soil to plant and animal life, the evolution of a soil profile, and the major kinds of soil in the United States. On a suggested field trip, students examine different kinds of soil profiles; they also measure soil acidity and water-holding capacity. Suggestions for further study are provided along with references…

Beerbower, James R. – 1971
This guide introduces the study of fossils and means through which this study may provide clues to ancient environments and geology. Presented are discussions about the origin of many types of organisms, origin of organic communities, evolution, and extinction of species. Suggestions are provided for likely collection sites, methods of collection,…

Hoyt, John H. – 1971
The study of beaches and their capacity as an interface between land, air, and water is presented. Students investigate shore phenomena to better understand the beach's history and possible future. Also discussed is the interaction between man and the beach, from weather effects to pollution. Laboratory investigations of samples collected from the…
