The articles in this book are arranged in five main thematic sections to give the reader quick and easy access to the subjects. The entries are drawn from Space, Our World, Nature, History, and Science and Technology. Articles are color coded to show which category they belong. Each entry has two parts: an information spread, giving a clear and concise introduction to the subject, and a Q&A spread that lets children explore what they have discovered. Cross references at the end of each article guide the reader to more information about a particular subject. There is also a comprehensive index.
