Papier-mache, plaster, and foam are inexpensive and versatile media for 3-dimensional classroom and studio art experiences. They can be used equally well by elementary, high school, or college students. Each medium has its own characteristic. Papier-mache is pliable but dries into a hard, firm surface that can be waterproofed. Plaster can be carved, draped, or cast from a mold before drying rigid. Foam comes in rigid and pliable forms. Each medium allows for experimentation with sculptural problems. Divided into two parts, part 1: "Materials of the Trade" presents: chapter 1 "Papier-Mache"; chapter 2, "Plaster"; and chapter 3, "Foam." Each medium is introduced by presenting its historic background, the nature of the material and its working characteristics, and methods and processes for working with the material. Chapter 4, "Designing and Planning Sculpture," looks at design concept and use of armatures. In part 2: "Getting to Work," a variety of project lesson plans are given for working with each medium in the creation of the following objects: chapter 5, "The Mask"; chapter 6, "The Headpiece"; chapter 7, "Creatures Real and Imagined"; chapter 8, "Puppets"; chapter 9, "The Human Figure"; chapter 10, "Construction and Assemblages"; and chapter 11, "All the World's a Stage." The book concludes with sources for materials, a glossary, and an index. Contains 13 references. (MM)
