" Nature's Miracles " titles encourage children to explore the natural world for themselves by observing nature's activities. The books also encourage kids to take part in activities of their own that promote a sense of responsibility toward the Earth's plants, animals, and natural resources. Each book presents a cheerfully illustrated story about children who explore nature's wonders. Notes for parents and teachers that follow each story suggest activities, further reading, and Web sites related to the book's theme. Color illustrations on every page. In this book, children discover a caterpillar in their Mom's backyard garden. Over a period of many days they watch as the caterpillar changes into a chrysalis that hangs from a tree branch, and then emerges at last as a beautiful butterfly.
