In 1872, Congress passed legislation to create the Yellowstone National Park, intending the land to be preserved as "a public park or pleasuring-ground for the benefit and enjoyment of the people." That was the first of many steps at the federal level to create and preserve national land, forests, coastal regions, wildlife refuges, and historic sites for future generations. In 1916, the National Park Service was created to oversee and protect the growing number of parks.

Today, there are more than 400 areas, including 59 fully designated national parks, across the nation under the domain of the National Park Service. They range from the tiny Thaddeus Kosciuszko National Memorial in Pennsylvania, which comprises only .02 acres, to Alaska's massive Wrangell-St. Elias National Park and Preserve, spanning a vast 13.2 million acres.

Celebrate them all during National Park Week, April 21–29. The National Park Service is celebrating by waiving entrance fees to all parks April 21 and by sponsoring a variety of events around the country (including Junior Ranger Day on April 21 and Military & Veteran Recognition Day on April 28).

These Science NetLinks resources provide a variety of rich media learning experiences to help students find out more about our national parks and conservation.
