Brainstorming Cognitive Map: (See attached paper) Content Overview: The Ocean is the great body of water that covers 71 per cent of the earth's surface. It is also referred to as the sea. The world is really one huge ocean, broken here and there by islands that we call continents. The ocean is so large that you can sail across it for days without seeing any land. It is also very deep with the bottom lying more than six miles below the surface.
It is important to have an understanding of the ocean because it directly or indirectly affects all life on earth.
Although we in the United States only get a small proportion of our food from the ocean, there are many nations that border the sea and depend highly on it. There are also many nations who are struggling for fresh water supplies. Although only a small amount of freshwater can be obtained from saltwater, scientists are working on new methods that will enable them to do so more efficiently. Other products like seaweed can be used to make many food products such as ice cream, candy, jellies, and salad dressing. More importantly, it is a vital ingredient in many medicinal products. The Sea is also a source of energy. And we someday will be able to use it to light our homes and run factories.
There are five oceans in the world. The three great ones are the Pacific, Atlantic, and the Indian Ocean.
