The Delaware Water Gap National Recreation Area encompasses 70,000 acres of ridges, forests, lakes and rivers on both sides of the Delaware River in the states of New Jersey and Pennsylvania. The Delaware River, the only remaining undammed river in the eastern United States, is part of the National Wild and Scenic River system; its exceptional quality waters provide both recreation and drinking water for millions of people in neighboring metropolitan areas. With habitats ranging from rivers and ponds to dry ridge tops, Delaware Water Gap is home to a variety of animals, from black bears weighing up to 800 pounds to ruby-throated hummingbirds, only 3-4 inches long. The Delaware River and its tributaries are home to more than 60 fish species, including both species that make the park their permanent home and migratory species such as eels and American shad that travel between the upper reaches of the river and the Atlantic Ocean. Great blue and green-backed herons wade in shallows looking for fish, frogs, and crustaceans for a meal. Otters glide silently through the water. On the river's floodplain, rich soil supports bountiful farm fields. Visitors can commonly see white-tailed deer and wild turkey searching for food. After nightfall, the park comes alive with a whole new set of animals: foxes, coyotes, bobcats, raccoons, and, in the night sky, owls, and six species of bats.

The North Country National Scenic Trail links scenic, natural, historic, and cultural areas in seven northern states. The approximately four thousand mile long trail incudes a variety of hikes from easy walking to challenging treks.

From the Missouri River in North Dakota to the shores of Lake Champlain in New York, the trail allows hikers to experience a variety of features, from clear-flowing streams, to thick Northern woods, from vast prairies to clean lakes.

The longest free-flowing river in the Northeast, it includes riffles and Class I and II rapids between placid pools and eddies. Public fishing and boating accesses are provided, although most land along the river is privately owned. Wintering bald eagles are among the wildlife that may be seen here. This unit of the National Park Service is also home to John Roebling's Delaware Aqueduct and the Zane Grey Museum in Lackawaxen, PA.

The lower Delaware River region contains immense resource diversity, combining an area of high population density with a wealth of natural, cultural, and historical resources and recreational opportunities.

The river itself provides habitat for American shad, striped bass, and river herring and is an important component of the Atlantic Flyway, one of four major waterfowl routes in North America. From a historic veiwpoint, the river is one of the most significant corridors in the nation, containing buildings used during Washington's famous crossing, historic navigation channels, Native American and colonial archeological sites, and 19th century mills.

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.

Based on Charlotte Mason's method of education, this website offers ideas and resources for incorporation nature study into your homeschool.
