Woods: One Small Square

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.
