Today a caterpillar came to school in a jar. Each day the children in the classroom watch in amazement as the caterpillar eats and grows, shedding its skin several times, until it disappears inside a shell that it creates for itself. For a long time nothing seems to be happening. But one day the chrysalis breaks open, and a beautiful Painted Lady butterfly flies out of the jar. Deborah Heiligman and Bari Weissman depict the metamorphosis from caterpillar to butterfly with all the wonder of those seeing the transformation for the first time. 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. This title features colorful illustrations from veteran illustrator Bari Weissman and lively text from National Book Award finalist and Michael L. Printz Honor winner Deborah Heiligman.Now rebranded with a new cover look, this NSTA/CBC Outstanding Science Trade Book includes web research prompts and an 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.This is a Level 1 Let's-Read-and-Find-Out, which means the book explores introductory concepts for children in the primary grades and supports the Common Core Learning Standards and Next Generation Science Standards.
