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.
