In a series of five activities, students will explore the question, "Will there be enough freshwater?" Students explore how water moves above and below Earth's surface by using interactive computational models. Students use NOAA data through a series of interactive modules to answer questions. Students are instructed to answer questions in boxes embedded in the website. Teachers will need to set up a free account with High-Adventure science in order to print out student responses. Additional information for teachers on how to use this activity can be accessed at: http://education.nationalgeographic.org/lesson/will-there-be-enough-fresh-water/.
In the first activity, Availability of Freshwater, students are introduced to computational models and begin to use them through the availability of freshwater interactive to answer the question of distribution of water and how water cycles. In the second activity, Using Freshwater, students examine maps to determine distribution of freshwater sources and how humans use them. The third activity, Groundwater Movement, has students learning how water moves through sediments and then using interactive models, determine the best ways of extracting groundwater with the fewest environmental impacts. With the fourth activity, Groundwater and Surface Water, students explore how the introduction of wells affects the water table using a computer simulation. In the final activity, Using Groundwater Wisely, students use interactive models to explore the relationships between infiltration and recharge in both natural and urbanized areas. They also explore how humans have altered the natural flow of water.
