The Worm Guide: A Vermicomposting Guide for Teachers

This guide explores vermicomposting--the practice of using worms to transform food waste into a nutrient-rich finished product called vermicompost. In a school setting, vermicomposting can set the stage for a variety of fun, interdisciplinary activities.

Vermicomposting can utilize school cafeteria waste for the worm bin, provide a variety of interesting experiments while maintaining the bin in the classroom, and can culminate in a school or classroom garden using the finished product.

To receive a free hard copy of The Worm Guide, call (916) 341-6769, or you can download it here (PDF, 3.5 MB). This new Worm Guide replaces our previous publication--Worms, Worms, and Even More Worms. Classroom activities from our previous publication (PDF, 401 KB) are still available.
