This is one of a series of units for environmental education developed by the Highline Public Schools. The unit is designed for use by art classes at the secondary school level; it illustrates the availability of natural clay and provides the student with experiences such as digging the clay, locating desirable clays, preparing it for production, and the use of the material as a means for creating pottery. Seven lessons are included in the unit. The field trip portion of the unit requires location of a site to obtain clay. The materials were tried and evaluated; evaluation data may be obtained from the Highline Public Schools. (RH)
