The National Wildlife Federation, on its website GreenHour.org, recommends that parents give their kids a “Green Hour” every day—a time for unstructured play and interaction with the natural world. Whether in the backyard, the local park, or a green space farther afield, time spent outdoors is essential to the healthy development of young minds, bodies, and spirits.<br><br>Todd Christopher, the creator of the GreenHour.org, has filled this book with activities designed to encourage discovery, creative play, and a wonder of nature. Here you'll find a range of projects, fun facts, and science lessons meant to engage and invigorate your child, as well as the practical advice for parents that makes getting outdoors easy and worry-free. With creative, science-based ideas for a variety of natural settings, getting your family's daily dose of nature just got easier.<br><br><iframe title="YouTube video player" width="480" height="390" src="http://www.youtube.com/embed/8RigUAwYcVU" frameborder="0" allowfullscreen> </iframe>
