    The students will learn about surface water and groundwater and their role in the water cycle, the development of cities, and the impacts of human intervention. Using examples of the Hoover Dam and High Plains aquifer, the students will work closely with real-world data to draw their own conclusions about the future of water.\u00a0<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

      1. Water disappears: Some students may think that water simply disappears when it evaporates or falls as precipitation. They may not realize that water is continually cycling through the different stages of the water cycle.<\/li>
      2. Water comes only from rain: Students may believe that rain is the sole source of water, overlooking other forms of precipitation such as snow, sleet, or hail. They may not fully understand that water can be present in different states and can transition between them.<\/li>
      3. Water only exists on the Earth’s surface: Some students may not realize that water also exists in the atmosphere as water vapor. They may think that water is only found in oceans, lakes, and rivers.<\/li>
      4. Water always evaporates from the same place it condenses: Students may have difficulty grasping that water vapor can travel long distances before condensing to form clouds and eventually precipitating as rain or snow. They may think that the water evaporated from the same area it falls as precipitation.<\/li>
      5. The water cycle is a one-time process: Some students may not recognize that the water cycle is an ongoing, continuous process. They may believe that once water falls as precipitation, it never returns to the atmosphere.<\/li><\/ol>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

                Teacher Simulation: What if all of Earth\u2019s water was only 1 gallon? (Slides 5-10)<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

                Hold up the gallon of water. If you want, emphasize how heavy a gallon of water is. You can have different students come up to the front to feel it as well.<\/p>

                State to the class:<\/p>

                This is all the water of planet Earth.<\/p>

                This is the water that is seen from space in the oceans that make people call this the blue planet.<\/p>

                This is the glaciers that make up the northern and southern poles and rest atop mountain ranges. This is the rivers, the lakes, the tiny ditches along a rural road filled with water. This is the precipitation from every single rainy day for which you have ever been alive. This is the water in your afterschool sports drink, the water in your faucet used to brush your teeth, the water used by farmers to irrigate their crops, the water required to complete nearly every single task on this planet. Pour the gallon of water into the glass or clear container.<\/p>

                Allow students to predict how much water is available for our use<\/p>

                Measure out 8 tablespoons from the clear container, pour the back into the gallon jug, counting aloud as you go. Hold up the still nearly empty jug and state to the class: this is all the water NOT in the ocean, which is about 3% of all the water on planet Earth. All the rest of this water is what makes our Earth blue, the salty waters of the oceans that separate our continents and communities.<\/p>

                Measure out 1 1\u20442 tablespoons out of the 8 tablespoons from the gallon jug and pour back into the clear container and state to the class:<\/p>

                Unfortunately, about .5% of the Earth\u2019s water is still salt water even though it\u2019s NOT in the ocean, so it\u2019s also not usable by humans. This includes landlocked bodies of water like the Great Salt Lake and the Dead Sea, which can have an even higher salt concentration than the ocean.<\/p>

                We also have something called brackish water, which is a mix of salt and freshwater.\u00a0<\/p>

                Hold up the even more empty jug, now with just 6 1\u20442 tablespoons, and state to the class:<\/p>

                This means only 2.5% of the Earth\u2019s water is truly fresh water.<\/p>

                Measure out 4 1\u20442 tablespoons out of the 6 1\u20442 tablespoons in the gallon jug, pour back into the clear container, and state to the class:<\/p>

                However, 1.7% of the Earth\u2019s water, although it\u2019s fresh, it ISN\u2019T accessible because it\u2019s frozen as glaciers, trapped underground, or otherwise unavailable to humans.<\/p>

                Hold up the gallon just with only 2 tablespoons left and state to the class:<\/p>

                This is all the water, less than 1% on planet Earth that is fresh AND available to sustain all the human, animal, and plant life that has existed, currently exists and will exist in the future.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

                Have students draw what they know of the water cycle. Ask them to think about the ways we know water is stored on Earth.\u00a0<\/p>

                This can be done on a piece of paper or on a whiteboard as a group.<\/p>

                As a class, build a model of the water cycle. It should be simplistic at this point. The model should be available for the class to refer back to throughout the remainder of the unit.<\/p>

                Build it together so that students have a starting point to work from as they develop the models into more sophisticated representations of the water cycle.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

                We think it can be useful for learners to first build a model as a group on a whiteboard.
