What is a forest? This engaging teacher's guide explores forest diversity, from learning about different kinds of trees, to understanding how the "layers" in a forest provide habitat for all kinds of animals and insects. How do sun and shade, wind, water, and soil affect the forest? What do trees need to grow straight and strong, and how are they turned into boards or paper or other forest products? How do you read signs of wildlife in the woods, and what kinds of animals live where? Each chapter offers useful introductory material and clear objectives, followed by fun activities that encourage exploration while teaching important skills-perfect for a classroom unit on the forest, but also a wonderful teaching tool at nature centers or for homeschoolers.
