One of the aims of the curriculum reformers of the past two decades has been to make science courses more relevant to the learners. Attempts have heen made to accomplish this by relating- art to chemistry in interdisciplinary, individualized, and consumer-oriented curricula. The two descriptions which follow provide examples of some successful approaches which could be utilized, in whole or in part, to supplement any programs in use in the secondary schools.

The Unigraph learning activity packages (LAPS)attempt to relate chemistry to the "real world" of students while teachina fundamental chemical principles. The general organization comprises a packet forthe teacher which includes a teacher's auide and ditto masters for all of the student materials. The student packet follows this schema: a rationale; an overview; stated behavioral objectives; a pre-test; three segments of instruction, laboratories, and quizzes; a glossary; answers to the pre-test and quizzes; and a comprehensive post-test. The teacher's materials include, in addition to a n annotated version of the student's materials, suggestions for laboratories and instruction, as well as suu~lementary references to peri.odicals and films. The instructional segments include the following con. tents The Story of Color Part One: A. Six major colors B. Prism refraction C. Chromatography The Exotic Moleeules-Natural and Synthetic Part Two: A. Dyes: fast, direct, coal tar B. Function of a mordant C. Synthetic versus natural dyes

The first of these units is "The Preparation of Paint." In it, the students produce naint and perform a quality test on their product. The chemistry needed f& the understanding of these processes and products, and consequently, the chemistry content of this unit includes Title:

Related terminology, and some history of the development of paints as well as chemistry, supplements the lahoratory work. The student text is interestina- and not overlv technical or difficult reading for the average high school chemistry student. In addition to this, there is a student laboratory manual. CHEMS films, U.S. Bureau of Mines films, supplementary worksheets, and outside reading on the history of specific processes are recommended as supplements. The editor invites teachers who have developed novel materials, or who have found some commercial product useful, to send i t directly to the editor of this feature.
