Teacher Notes: Describe the characteristics of water and demonstrate where water is found on the earth. When we discuss the hydrosphere we include all the water on the earth. Though both fresh and salt water represent a tremendous resource and cover about 75 percent of the earth's surface, students sometimes fail to think about the water vapor in the air, the snow and ice of the arctic and mountain tops or the ground water stored in the porous rocks and sediment beneath the earth's surface. Elementary students should recognize water in its various states. Young children seem to have little trouble understanding the solid and liquid states of water yet frequently assume that when water evaporates it disappears. Even though it may be more difficult to understand how liquid water evaporates and then can condense into a liquid again, this concept is essential to understanding the hydrosphere as a resource.
