Introduce your class to the life cycle of the earthworm. Students collect food to feed the worms and learn how recycling leftover food makes soil. They also learn to maintain the worm habitat. Each kit comes with redworms, a 1 1/2-gal terrarium with lid, soil, worm closet (for keeping worms in the dark), rocks, and a fork for stirring food into the soil. Complete with teacher information on habitat and feeding.
