A series of soil and water books for kids has been created by University of Illinois Extension. The series, called the "Secret Agent Worms," features the zany antics of two "spy" earthworms. The Disappearing Earth takes the worms through the soil erosion process, and Beneath the City of Ooze gives readers a worm's-eye view of storm water pollution. Kit contains teacher's packet and replaceable items like different soils, pans for soil run-off, etc.
