A caterpillar comes to school in a jar and the class watches the caterpillar each day as it grows and changes. Soon, it disappears into a hard shell called a chrysalis. Where did it go? This is a perfect beginner’s guide to the mystery of metamorphosis.
 
Named as a NSTA/CBC Outstanding Science Trade Books for Children, this book explains the life cycle from caterpillar to butterfly with easy-to-follow prose from Deborah Heiligman and warm, colorful illustrations from Bari Weissman.
