UNDER YOUR FEET: Soil, Sand, and Everything Underground

Delve beneath the Earth's surface and explores the diverse wonders hidden there. Encounter creatures of the deep and marvel at the size of the humongous fungus--the biggest organism in the world. Learn how one handful of ordinary soil contains more organisms than there are people on Earth, and carry out experiments using dirt from your own back garden. Ages 5-8. Fully illustrated in color.
