Part of the "Eyewitness Explorers" series, this book includes practical information for children aged 7 and above with photographs and illustrations designed to help explain the concepts examined. This particular book is designed to help children watch and understand the changing weather, with projects and instructions including how to make a rain gauge, construct a simple barometer or make a weather diary. Specially built models show how water evaporates or how hot air rises in a vivid three-dimensional way. Amusing illustrations of weather facts and folklore introduce a fun element into this book.
