After a caterpillar comes to school in a jar, the children are captivated as it eats, grows, and eventually becomes a beautiful Painted Lady butterfly. National Book Award finalist Deborah Heiligman and veteran illustrator Bari Weissman depict metamorphosis with all the wonder of those seeing the transformation for the first time.Now rebranded with a new look, this NSTA/CBC Outstanding Science Trade Book includes web research prompts and an additional activity encouraging kids to identify the different types of butterflies all around them! Both text and artwork were vetted for accuracy by Dr. Louis Sorkin, Senior Scientific Assistant at the American Museum of Natural History.
