Greenbelt Park is a retreat from the pressures of city life and a refuge for native plants and animals just twelve miles from Washington, D.C. Long before colonial settlers appeared here, trees and flowers covered these rolling hills and wildlife roamed the woodlands. Algonquin Indians hunted this land in competition with other smaller tribes. A balance existed between the land and its plants, animals, and native people. Then the colonists arrived. Trees fell and forests gave way to farmland. Wildlife retreated to the frontier. For the next 150 years, people cleared the land, plowed the fields, and planted tobacco, corn, and other crops. The rich fertile soil returned high yields. The people did not give back to the land as much as they took. The land wore out, producing less each season and farming ceased. The land was left bare and defenseless. Erosion caused many scars before nature could slow the process with new growth. Since the early 1900's the land has been recovering.. Today the mixed pine and decidious forest testifies to the land's ability to recover.

Storm tossed seas, as well as gentle breezes shape Assateague Island. This barrier island is a tale of constant movement and change. Bands of wild horses freely roam amongst plants and native animals that have adapted to a life of sand, salt and wind. Special thickened leaves and odd shapes reveal the plant world’s successful struggle here. Ghost crabs buried in the cool beach sand and tree swallows plucking bayberries on their southward migration offer glimpses of the animal world’s connection to Assateague.

ExploraVision is a competition for all students in grades K-12 attending a school in the U.S., Canada, U.S. Territory or a Department of Defense school. Homeschooled students are eligible to enter. It is designed to encourage students to combine their imagination with their knowledge of science and technology to explore visions of the future. Teams of students select a technology, research how it works and why it was invented, and then project how that technology may change in the future. They must then identify what breakthroughs are required for their vision to become a reality and describe the positive and negative consequences of their technology on society. Winning ideas have focused on things as simple as ballpoint pens and as complex as satellite communications. The student teams write a paper and draw a series of Web page graphics to describe their idea. Regional winners make a Web site and a prototype of their future vision.
