Properties of Water

There is probably not another substance on earth as incredible and essential, yet so common and so taken for granted (when there is enough of it), as water. You interact with water every day, and probably never really think about how amazing each molecule is. View the clips Water and Mystery of Water from eMediaVASM. As you view the videos, consider the following questions:

• How did Earth get water?
• How much water is usable by humans?
• Why is it important to conserve water?
