Just south of Atlantas busy Hartsfield-Jackson International Airport, Clayton County seems like an obvious place for metropolitan growth. But more homes and businesses mean a higher demand on the countys limited water supplies.

This activity is a 3 part lab activity where students create a model of an area in a community. The students test how dirty water flows through their models observing where water is filtered or not. Using what was learned by the models, students will draw a community scene that has man made areas alongside areas that benefit groundwater filtration.

This virtual field trip takes students to the site of a local groundwater controversy in Gallatin Valley, Montana. Students virtually travel through seven stops which highlight the groundwater hydrology, local geology, geologic history of the valley and local groundwater policy. During the virtual field trip, students are asked to role-play as geologists hired to evaluate the area. Ultimately, they are asked to formulate an argument for or against the development of a nearby subdivision and to support that argument with evidence they gathered on the virtual field trip. Evidence may include observational field notes, hypotheses and questions regarding the geology and geohydrology of the area as well as limited hydrological data. Students must produce a final report discussing the decision they made as a consulting geologist. Reports should include a well-supported argument using the data and information collected during the virtual field trip. This virtual field trip gives students an opportunity to explore a local dispute regarding groundwater and learn how geology, geohydrology and scientific data are involved in policy issues.

This is a short NASA video on the water cycle. The video shows the importance of the water cycle to nearly every natural process on Earth and illustrates how tightly coupled the water cycle is to climate.

Students learn about floods, discovering that different types of floods occur from different water sources, but primarily from heavy rainfall. While floods occur naturally and have benefits such as creating fertile farmland, students learn that with the increase in human population in flood-prone areas, floods are become increasingly problematic. Both natural and manmade factors contribute to floods. Students learn what makes floods dangerous and what engineers design to predict, control and survive floods.

This exercise demonstrates the role of groundwater in Earth's surface processes and natural hazards through a simple sensitivity analysis using Excel and a case study of a landslide in glacial sediments. In the first part of the exercise, students use a spreadsheet to model the infinite slope equation to determine which variables are sensitive to change. In this part of the exercise students discover the relationship and importance between hydrogeology and Earth's surface processes. In the second part of the exercise students use a case study, of a landslide that occurred in glacial sediments, to calculate the lag time between precipitation events and slope failure. This exercise highlights the relationship between groundwater and natural hazards. Finally, students combine their knowledge of both exercises and use the infinite slope equation to predict the percent of ground saturation for the landslide case study.

Students conduct a regional watershed analysis of an area of their choosing. Using on-line data and their personal knowledge of the area, they determine the annual hydrologic budget and teach the class about "their" watershed.

Students learn about the water cycle and its key components. First, they learn about the concept of a watershed and why it is important in the context of engineering hydrology. Then they learn how we can use the theory of conservation of mass to estimate the amount of water that enters a watershed (precipitation, groundwater flowing in) and exits a watershed (evaporation, runoff, groundwater out). Finally, students learn about runoff and how we visualize runoff in the form of hydrographs.

This activity is a classroom based inquiry activity where students will observe how water changes when it is moved through a variety of different mediums. Eventually, the students will take this model to the larger ideas of watershed in the community.

Students use USGS WaterData website to find data on area, average annual discharge and response to high-precip events in small watersheds in southern New England. Data for the class are compiled to generate graphs showing the regional relationships between (1) area and discharge, and (2) area and time-lag between precip and maximum discharge.
terms: discharge, watershed, flood

This activity is a class activity where students gather information of the water cycle, weather and seasons by doing a lab and game that enforces the concepts of the water cycle.

Students read one of two articles (the "cases") from High Country News, a bi-weekly periodical that covers environmental issues in the western North America. Both articles are about situations in which the use of ground water by irrigators has decreased the amount of surface water available for users with senior water rights. I divide the class into groups representing 1) surface water users, 2) ground water users, and 3) a regulatory board. The groups read and discuss each article and prepare a case to present to the regulatory board. After each group has prepared their case, we gather for a hearing, where groups of consultants present their cases and are questioned by the regulatory board. At the end, the regulatory board makes "decisions" on each "case". The decision isn't the focus of the exercise. The most valuable part is the subsequent discussion about the cases and the common issues in them that get the students to recognize the connection between surface and ground water and how humans have come up with confusing and sometimes scientifically conflicting sets of laws to regulate each.
