This detailed-oriented book by David Macaulay could practically serve as a biology-textbook! Moving from cells, atoms and molecules all the way to birth, The Way We Work is a whirlwind tour through the most amazing machine of all--You! Often humorous colored-pencil illustrations provide an uncannily clear portrait of how ATP works, why muscles move, how molecules are formed, the systems of the body, and more. Using the biologically correct terms found in high school or college textbooks, students will receive an understanding of the human body in short, easy to digest segments accentuated by his trademark visual explanations. This book is perfect for keeping around the house as a gradual introduction to biology and anatomy; elementary students may be intrigued by the illustrations (though the text is advanced), while middle school and high school students should be able to gain a fantastic introduction to the subject. 336 pages, hardcover with dust jacket. Recommended for ages 10 and up.
