How & Why Stories — Martha Hamilton; Mitch Weiss

Did you ever look carefully at a spider's web? If their purpose is strictly to catch flies, why do spiders weave such beautiful, intricate webs? Did you ever wonder what causes thunder? Why is the sea salty? How did tigers get their stripes? In this collection of delightful tales from around the world and through the ages, each story explains why an animal, plant, or natural object looks or acts the way it does.
