After creating a model, students will investigate factors that affect water runoff both positively and negatively, and the impact this has on the quality of groundwater.

Rainforests at the Crossroads: Examine the relationship between rainfall and runoff on Barro Colorado Island (BCI) over a period of one year. Then examine the data and use the TI-73 Explorer to graph and analyze the values.

A demonstration that shows students how water systems are connected and the concept of non-point source pollution. Also it allows students to see how pollution on their playground could affect larger water supplies.

This lesson teaches the concept of a watershed and why it is important in the context of engineering hydrology. Learners learn about runoff and how we visualize runoff in the form of hydrographs.

This website focuses on water quality issues in relation to urbanization. There are helpful links to brief articles on topics like storm runoff, wastewater, and the underground water table. Click "Water Science School HOME" to access the...

Rainforests at the Crossroads: Collect runoff from two simulated sites: 1) a tray with soil, 2) a tray with soil and vegetation, to see how vegetation affects erosion and to compare and examine the runoff from the sites.

This lesson helps young scholars discover the relationship between precipitation, evaporation, and surface runoff data. Using FieldScope, an online GIS created at the National Geographic Society, students will explore data layers, create...

The most common problem on the Catawba River and its lakes is sedimentation. Sediment carried by stormwater runoff from construction sites in North Carolina has been documented as the leading source of non-point source pollution to...

A simple experiment that demonstrates how water is absorbed into soil and filtered through it, showing how water changes things in the environment. After a class demonstration, they will themselves investigate the effects of water...

A collection of video lectures from a course on water resources engineering. Webpage includes twenty-eight lectures from a professor at the National Programme on Technology Enhanced Learning. Lectures vary in length and cover topics like...

Solve the crossword puzzle and learn more about stormwater and runoff pollution.

Students learn about the Earth's water cycle, especially about evaporation. Once a dam is constructed, its reservoir becomes a part of the region's natural hydrologic cycle by receiving precipitation, storing runoff water and evaporating...

[Free Registration/Login may be required to access all resource tools.] An introduction to the biogeochemical cycle, the water cycle. Recognize evaporation, sublimation, and condensation. Identify groundwater and runoff water supplies.

This U.S. Geological Survey website offers a short article then lists topics that are linked to brief articles that describe that particular topic's effect on water quality in urban areas. Click Home to access the site in Spanish.

Water is the source of life on earth. It exists in many forms and is constantly changing. The circulation and conservation of earth's water is called the hydrologic (or water) cycle. Find out how water evaporates, condensates,...

In this field lab, learners investigate the differences in three city ponds. Students will compare pond life, temperature, pH, Ammonia, dissolved oxygen, and Nitrate. The student use the pond sheets (Flinn Scientific Catalog 2007) to...

This interactive tutorial discusses the flow of water on the surface and below the surface. You will learn about the causes and actions of wind, and how water and wind move sediment.

Overview and maps of the Gulkana Glacier along the south flank of the eastern Alaska Range.

Students apply their understanding of the natural water cycle and the urban stormwater water cycle, as well as the processes involved in both cycles to hypothesize how the flow of water is affected by altering precipitation.

Student groups create personal rain gardens planted with native species to provide a green infrastructure and low-impact development technology solution for areas with poor drainage that often flood during storm events.

Through an overview of the components of the hydrologic cycle and the important roles they play in the design of engineered systems, students' awareness of the world's limited fresh water resources is heightened. The instructional...

A collection of resources--pictures, maps, data, glossary--about water and the water cycle.

This virtual field trip for middle school students looks at aquifers and their place in the hydrologic cycle. Students learn why and how it is important to protect the source of your drinking water and some unique details about the...

Check out this simple overview of the water cycle and learn how to build a model of the water cycle.
