Take a ride with Pitter on a water cycle! Tumble from the sky, careen off a leaf, plunge into a stream as you travel through a watershed. Then take a ride with Patter—even through an underground cave. Oh, the places you’ll go and the creatures you’ll see. A water drop is a wonderfully adventurous thing to be! Following the main story is a large, attractive schematic showing both the parts of the water cycle and how each drop took different paths through the watershed. An “Explore More” section for teachers and parents offers a clear presentation of states of matter.
