This book is a combination of two main topics: Science and History. Each main topic is latter broken down into subtopics like Flight and Ancient Egypt, and then even futher like Machines and Power of the Pharaohs. Each topic is given a double page full color spread. Each page is filled with illustrations, photos, detailed drawings, and a written description on the topic. This book doens't cover anything in great detail. It cannot. Because of its size and scope, it can only give the briefest of dicussion. Also, many of the topics are copyed from previous books in the series. This means that many of the topics in the science section have illustrations that are out of date with modern technology, such as using a picture of an Apple computer from the early 1990's for the computer topic in a book published in the 2000's. I would not recomend this for a high school class. If anything, it would be useful for a middle school class, but only a a starting off point. Their is also a lack of refferences that makes further research hard, since students will not know where they obtained the information for this book. Because of the books physical size, it is good to have if you are lacking in space in your classroom. ( )
