What: A bountiful Earth Day website for teachers and students, brought to you by The Wilderness Society.
Best parts: The site provides creative activities for students in Grades K through 12. Take a virtual tour of the Arctic National Wildlife Refuge through photos and one man's reflections during his three-month trek in the region adventures with grizzlies and philosophies on life included.
Or track the migrations of several bird species from the Arctic refuge to places farther south, using interactive maps and photos that identify the birds.
To follow the development of important conservation and environmental laws, you can view a downloadable timeline. And for the younger set, biographies on "planetary heroes" abound, along with a recent audio message from Sen. Gaylord Nelson, who founded Earth Day in 1970. There's also a downloadable coloring book on the animals of the Arctic refuge.
What you should know: The Wilderness Society, founded in 1935, works to protect America's wilderness through education and advocacy.
