  • Summarize why not all the earth's water is drinkable
  • Discuss the different types of water on earth
  • Examine and calculate personal water use
  • Formulate a personal water conservation plan
  • Evaluate the effectiveness of water conservation plan

Only about three percent of the world's water is available for drinking. As the world's population increases, more and more people need this natural resource. However, like all natural resources, there is not an infinite supply of water. In this investigation, students learn what it means to conserve water. Using an H2O diary, students will monitor their family's water use and propose methods for home water conservation.
