Even though the Earth is a water planet, humans are faced with the issue of a lack of clean water. This unit centers on access to clean water and is driven by the major question: “What can we do to ensure that we have continuous and sufficient access to clean water?”

Students will learn about the water crisis from a global and local perspective, including uses, trends, and predictions concerning water health and access, current events and issues affecting water use and availability, and potential emerging solutions for the water crisis. Students will analyze public data, develop and articulate positions on the various facets of the water crisis, create and use scientific models to understand the scientific and social aspects of the issue, reflect on personal stewardship, and work toward potential solutions.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    • Water continually cycles among land, ocean, and atmosphere via transpiration, evaporation, condensation and crystallization, and precipitation, as well as downhill flows on land.

      <\/li>
    • Global movements of water and its changes in form are propelled by sunlight and gravity.

      <\/li>
    • Variations in density due to variations in temperature and salinity drive a global pattern of interconnected ocean currents.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

      1.1 Where Does The Problem Exist<\/a><\/td>Introduce global scarcity of water.<\/td>1 hour<\/td><\/tr>
      1.2 How can I be affected?<\/a><\/td>

      Water goes from a source to taps through a series of steps.<\/p>

      Students will explore their local watershed and the possible impairments to it.<\/p><\/td>

      		45 minutes<\/td><\/tr>
      2.1 Where is water found?<\/a><\/td>

      Water is stored underground, on the surface and in the atmosphere.<\/p>

      There is very little accessible freshwater on Earth.<\/p>

      Water moves through Earth by the water cycle.<\/p><\/td>

      		3 hours<\/td><\/tr>
      2.2 How much water do we use?<\/a><\/td>We use more water than we think in visible and invisible ways.<\/td>1 hour<\/td><\/tr>
      3.1 What do we use water for?<\/a><\/td>Globally, water use is divided into three categories. From greatest use to least, it is (1) agriculture, (2) industry, and (3) municipal or household purposes. A country\u2019s water use distribution is somewhat determined by how developed it is.<\/td>1 hour<\/td><\/tr>
      3.2 What happens after water is used?<\/a><\/td>

      After water is used, it is either treated in a water treatment plant (sewage) or it will runoff into the ocean.<\/p>

      Pollutants are collected during the runoff process, which can have harmful consequences on the health of a water system.<\/p>

      Urbanization and an increased need for agricultural areas can affect the water cycle.<\/p><\/td>

      		3 hours<\/td><\/tr>
      3.3 Is the problem changing?<\/a><\/td>

      Climate change and population growth play a significant role in the growing water crisis.<\/p>

      Policies, economics, and cultural habits contribute to the complex nature of the water crisis.<\/p><\/td>

      4.1 What can society do?<\/a><\/td>The water crisis is a complex problem with complex solutions, there are often many options, but not all of them are good choices for governments to make.\u00a0<\/td>1.5 hours<\/td><\/tr>
      4.2 How can we \u201ccreate\u201d freshwater<\/a><\/td>The solutions to the water crisis will also involve technological innovations. These innovations come with affordances and constraints that must be considered when making decisions.\u00a0<\/td>1.5 hours<\/td><\/tr>
