#8 - The Science of Soil
Mar/Apr 2007
It's spring and we're playing in the mud. In this issue of KNOW, we're exploring the world of soil. How do we depend on soil every day? And how do animals use dirt and mud? You'll meet animals that build and bathe with soil! You'll also meet a man that plays with the mud for a living. As usual, KNOW includes poems, puzzles, activities, and experiments. And when you've finished playing the dirt, you can read up on soap to see how this great substance washes away grit and grime. So dig on in!
