Conservation is a concern for all cultures, and children are familiar with this concept because of recycling in their homes and home towns. The World Saver Center, an example of the thematic approach to learning, is designed to allow children to experiment with concepts of conservation in a familiar setting. The center, designed to resemble an early childhood classroom, is composed of five thematic areas: (1) art; (2) housekeeping; (3) blocks; (4) craft; and (5) garden (science). The World Saver Center focuses on conservation activities which can be done in a typical classroom, incorporating a multicultural theme into units. For each area, activity plans are given, including purpose, materials needed, teachers' involvement, and reflection statements. (BGC)
