With a hands-on approach, this book is all about asking questions and getting answers. How many teeth do you have? What happens to the food you eat? A little girl named Koko asks questions to make children think about the body, while three intrepid explorers go on adventures inside the body to find out what makes it work. Children investigate each topic by playing and learning. The book is packed with things to do--on and off the page--including games, recipes, and craft activities. The bold illustrations give the book a contemporary feel, and its large format is friendly to children.
