The Uncover It series combines the best elements of a book with model elements to help readers truly "uncover" the mysteries of what makes things work. A fascinating three-dimensional presentation allows in-depth, hands-on exploration of the subject at hand. This unique "model" is easily build, deconstructed and re-built layer by layer, system by system just by turning a page, until an understanding of the topic is achieved. The complexities of the human body can be daunting, particularly for children. By combining a 3-D model with informative text and pictures, Uncover the Human Body helps children understand how the body works. It covers all the major systems and processes. Children get to look at each system on a different page, then by closing the book, combine them into a whole.
