The woods are full of puzzles to be solved, clues to be found. Inspired by this book's hints and fun-filled experiments and activities, and using only simple equipment, young readers unlock the closely guarded secrets of the woods - from the strange meetings of lazy butterflies, to the miraculous "walking" of a twig, to the riddle of why the leaves turn color and fall. One small square at a time, these "detectives" plunge deeper and deeper into ancient mysteries - without ever getting lost. Beautifully illustrated, "Woods" offers a picture field guide, a glossary-index, and a resource list.
