Describes the necking of polymer sheets that occurs when they are stretched. Discusses the effect and the mechanisms of necking. Lists four references. (YP)

Provides background information on polymeric films and membranes including production methods, special industrial and medical applications, laboratory preparation, and an experimental investigation of a porous cellulose acetate membrane. Presents a demonstration to distinguish between high- and low-density polyethylene. (JM)

Describes three plastics projects (which involve making a styrene fishing bobber, an acrylic salad fork and spoon set, and acetate shrink art) designed to provide elementary level students an opportunity to work with plastics and to learn about careers in plastics production and distribution. (TA)

Discusses the product of alkenes, including isopropyl alcohol, ethylene, propylene, thermoplastics, and synthetic rubber. The developments and chemical formulas of the products are described. (YP)

Discusses the diversity of names used for various types of polymeric materials. Concentrates on the naming of linear organic polymers. Delineates these polymers by discussing common names, source-based names, characteristic group names, and structure-based names. Introduces the specifications of tacticity and geometric isomerism. (TW)

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…

This sourcebook, for use with groups of up to 25 young people ages 10 and up, is designed to stimulate a sense of environmental stewardship for the planet through group discussion, role playing, experimentation, demonstration, and simulation. Lessons that stand alone or can be used in sequence require common materials and little preparation,…

Suggests using plastic bags as aquaria and terraria. Describes techniques for converting plastic sheets into aquaria, how to set them up for classroom use, and other uses for plastic bag aquaria. (DS)

Information about the recycling and reuse of plastics, aluminum, steel, glass, and newspapers is presented. The phases of recycling are described. An activity that allows students to separate recyclable materials is included. The objectives, a list of needed materials, and procedure are provided. (KR)

Advocating that Canadian art programs should use and model environmentally safe practices, the articles in this journal focus on issues of safe practices in art education. Articles are: (1) "What is WHMIS?"; (2) "Safety Precautions for Specific Art Processes"; (3) "Toxic Substances"; (4) "Using Clay, Glazes, and…

Discusses the range of benefits resulting from recycling efforts and projects. Presents information and data related to the recycling of metals, cans, paper, fans, and plastics. Suggestions for motivating and involving youth in recycling programs are also offered. (ML)

Described is a series of four graduate level courses in polymer science, offered or currently in preparation, at Stanford University. Course descriptions and a list of required and recommended texts are included. Detailed course outlines for two of the courses are presented. (BT)

Classroom demonstrations of selected mechanical properties of polymers are described that can be used to make quantitative measurements. Stiffness, strength, and extensibility are mechanical properties used to distinguish one polymer from another. (KR)

Presents an overview of the teaching of plastics at various levels of technological education in the Netherlands focusing on mechanical engineering. Highlights the design process and discusses the Dutch perspective of the role of materials engineering in engineering curricula. (ML)

This curriculum guide provides materials for the industrial arts (grades 7-9) subject cluster of manufacturing. This subject cluster has four areas of study: metalwork, plastics, woodwork, and manufacturing. Introductory materials include an overview of the industrial arts curriculum in its entirety, a listing of program objectives for each of the…
