Why is the sky blue? Why do I have to sleep? Why do the birds sing? Why do I have to go to the bathroom? A walk in the park, taking a bath, helping Mom in the kitchen… with all these activities, a child asks a thousand and one questions. In this first question-and-answer book, many mysteries are unraveled in a clear and simple way. Your child will learn all about the hows and whys of what happens at home, in nature, in the supermarket, or on the farm. Catherine Ripley is an expert at answering children's questions. While working as an editor of a children's magazine, she began collecting questions from young readers. She visited schools and libraries and dedicated herself to making science fun and understandable for children. Catherine has written several successful children's books.
