2.04 Nature's Way: Recycling

We've made it! What a view! Don't you feel accomplished? Using all that energy climbing was worth it; wasn't it?

Look at all the water below us! Did you know that roughly 70 percent of the Earth is covered in water?

As you might guess, water is very important to all living things, even humans. We drink water. The foods we eat contain water. We use water to grow food, to bathe, and it is necessary to keep our bodies running properly. A few days (3-4) without water and humans will die.

In this activity you will: identify and learn the basic parts and functions of the water cycle. evaluate the importance of water in living things and identify reasons it must be conserved. identify and learn the basic parts and functions of the carbon cycle. identify the major sources of carbon in the earth's crust, oceans, and atmosphere and its importance to living things in the environment. explore the effects of human activities (fossil-fuel burning, deforestation) on the movement of carbon. The Honors student will: explain the importance of nitrogen in living things

Think about this:

If all living things need and use so much water, why doesn't the Earth ever run out of water?

Now, while you're thinking about that, get up and go to your kitchen, find an empty, clear glass, and put it in the freezer. It can't be plastic. Go on, walk away from the computer, and complete this task! When you finish, come back and we'll continue the trek.

You'll find out what to do with the glass later.
