Calling all Fourth Graders!

What do you know about America’s federal lands and waters? You can find them almost everywhere! From Puerto Rico to Maine and Virginia to the Pacific Islands, some of America’s most spectacular destinations await your discovery. There are more than 400 national parks and millions of acres of federal lands and waters.

Learn about your heritage and connect with nature near you. In Texas, you can visit cool places like the forests of the Big Thicket, find sea turtles at Padre Island, explore the history of the San Antonio Missions, and the home of President Lyndon B. Johnson, along with the canyons of Big Bend, and much more. Listen to howling wolves, check out prehistoric dinosaurs, paddle a river, walk in the footsteps of a President, or look up into a dark night sky and reach for the stars!

In addition to a pass to all federal lands and waters, fourth grade students in the Greater Houston Area can take advantage of the Open OutDoors for Kids (OOK) program. This effort is funded through a grant from the National Park Foundation and strives to eliminate barriers to field trip participation by reimbursing all transportation costs. Teachers can easily book a field trip with one of many national, state and local park partners who provide a variety of curriculum-based natural, cultural, and historical field trips correlated with Texas Essential Knowledge and Skills (TEKS).
