I Love Dirt!: 52 Activities To Help You And Your Kids Discover The Wonders Of Nature

Jennifer Ward
"This action-packed book encourages your child to love the outdoors by offering an array of activities, such as leaf looking and cloud racing, that can be done as near away as your own back yard."

Note: This book isn't exactly a children's book, but meant for an adult to read and to learn how to take on more activities with children outdoors. Teachers, moms, moms to be, and anyone else would enjoy.
