Byron and the rest of the team need a great deal of water every day. They use the water to prevent dehydration and reduce the risk of high altitude illnesses. Students might have an opportunity to use the Internet to discuss the importance of water and other nutrients with Dr. Virginia Robinson, the Everest 2000 team doctor. About two-thirds of your body is water.

Many foods have more water in them than you think. For example, an apple is about 80 per cent water. Students will observe the amount of water contained in a variety of foods. In the absence of familiar landmarks, people tend to follow a circular path. In this activity, blindfolded students attempt to follow a straight line to reach a distant landmark.
