The activities presented in this book encompass a variety of perceptual, social, and technological issues as they relate to the built environment. They are organized to present a coherent, cumulative series. Generalizations become specific as vocabulary is developed and planned techniques explained. Curriculum guide charts indicate subject areas related to each activity. Approximate grade levels and related subject areas also are given at the end of each activity. Chapter content areas are: (1) "Teaching Aids," which contains the vocabulary, an illustrated glossary, and suggestions for the introduction and reinforcement of architectural terminology; (2) "Design" focuses on general design principles essential to the nature of architectural planning; (3) "Materials" looks at the sensory and the structural aspects of building materials as a reference point for further study; (4) "Structures" gives exercises in the essential principles of building construction, many of which can be developed to demonstrate some of the basic laws of physics; (5) "Home" provides student activities with personally relevant built environments; (6) "Interiors" helps articulate responses to aspects of interior design and explains some of the professional architect's working methods. (7) "Exteriors" looks at a variety of facade elements and their functions; (8) In "Neighborhoods and Streets" students use drawings, maps, and photography to study a living community as an integral series of interwoven systems with direct impact upon the residents; and (9) "Cities" has students planning and constructing a model community based on various aspects of public and private life. A special section focuses on Philadelphia as a "Museum of Architecture." A 42-item bibliography concludes the book. (MM)
