This book provides clear answers to many questions that children ask, but also invites them to explore further and to ask many more questions. These clear and concise answers to 150 questions about the natural world, the human body, urban life, everyday life and human history are accompanied by more than 250 detailed and lifelike illustrations that help children visualize and contextualize the answers. Many of the larger illustrations are labeled, enabling children to build their vocabulary, and there is a quiz at the end of the book.
