Three creative educators collaborated to produce this guide for classroom and home. Centered around a classroom worm bin, this curriculum uses over 150 worm-related activities to develop problem-solving and critical thinking skills in children grades 4-8. Rich in content in "Wormformation" paragraphs integrates science, mathematics, language arts, biology, solid waste issues, ecology, and the environment in ways that draw children into the learning process. Three sections include "The World of Worms," "Worms at Work," and "Beyond the Bin." Includes 16 appendicies, resource materials, teacher's guidelines, bibliography, glossary, and index.
