The book "Nature's Playground: Activities, Crafts, and Games to Encourage Children to Get Outdoors" encourages children to venture into the world of the outdoors. Hours of inventive, exciting and safe outdoor activities for children are included, organized by season--or to do all year round.

Teachers can easily adapt the included activities for their use in the classroom, on school grounds, on field trips or for children to do with their families. This article describes a sample activity from "Nature's Playground" for those experiencing winter with freezing temperatures and for those who don't.
