Standard 4.8 - Natural Resources
The student will investigate and understand important Virginia natural resources. Key concepts include
a) watershed and water resources;
b) animals and plants;
c) minerals, rocks, ores, and energy sources; and
d) forests, soil, and land.

The concepts developed in this standard include the following:
· Virginia is rich in a wide variety of natural resources including forests, arable (farmable) land, coal, sand and aggregates (rocks), wildlife and aquatic organisms, clean water and air, and beautiful scenery.
· A watershed is an area over which surface water (and the materials it carries) flows to a single collection place. The Chesapeake Bay watershed covers approximately half of Virginia’s land area. The other two major watershed systems are the Gulf of Mexico
and the North Carolina Sounds.
· Virginia’s water resources include groundwater, lakes, reservoirs, rivers, bays, and the Atlantic Ocean.
· Virginia has a great variety of plant and animal resources.
· Natural and cultivated forests are a widespread resource in Virginia.
· Virginia’s soil and land support a great variety of life, provide space for many economic activities, and offer a variety of recreational opportunities.

In order to meet this standard, the student will need to be able to:
· compare and contrast natural and man-made resources.
· distinguish among rivers, lakes, and bays; describe characteristics of each; and name an example of each in Virginia.
· create and interpret a model of a watershed. Evaluate the statement: “We all live downstream.”
· identify watershed addresses.
· recognize the importance of Virginia’s mineral resources including coal, limestone, granite, and sand and gravel.
· appraise the importance of natural and cultivated forests in Virginia.
· describe a variety of soil and land uses important in Virginia.
