This unit, developed by the Third World Science Project, is designed to add a multicultural element to existing science syllabi (for students aged 11-16) in the United Kingdom. The project seeks to develop an appreciation of the: boundless fascination of the natural world; knowledge, skills, and expertise possessed by men/women everywhere; application of knowledge and skills to solve the practical problems of everyday life; impact of modern technology in the world; and the influence of the cultural background on the perception of knowledge, problems, and solutions. The unit consists of three sections. Section 1 is an account of how traditional clay pots are made in Sokoto (Northern Nigeria). Section 2 consists of: an experiment to discover how to keep water cool in porous pots; information on why water stays cooler in porous pots and on how water passes through the walls of these containers; and a discussion of advantages of using clay pots for cooling water, especially in rural areas of developing countries. Section 3 is a discussion of village pottery production in the Philippines. Suggested activities include constructing a Taku Kiln from a dust-bin or oil-drum, simple glazing experiments, and hand-built pottery using coiling or slab techniques. (JN)
