Why do I have to wash? Why don't aeroplanes fall down? Where do mountains come from? Why is the sea blue? Why do I dream? This book invites young people to discover more about the world around them by asking and answering questions for themselves. The book is structured around twentytwo questions, each one tackled over two spreads. The first spread explores the question and answer, supported by a detailed illustration, photograph or diagram. The second spread asks further questions on a similar theme to help build an understanding of how science underlies everything from the ingredients in our fridge to reaching the moon. The tone of the text is fresh and informal without being flippant.
