Learners find ways to decrease soil runoff for an African Village as a part of a Peace Corps project. For this soil runoff lesson, students play a soil runoff challenge online. Learners complete online activities and view a slide show to...

Young scholars examine the causes and effects of soil runoff. In this environment lesson, students look at ways in which soil runoff is controlled. Young scholars then play a game  and discuss how the Peace Corps deals with soil...

Thirsty plants soak up every bit of a rainfall, but what happens to the rain that hits the roof? Calculate the amount of rainwater from your school's roof with an Earth science activity, which brings measurement skills, observation...

Students map and calculate the area of the school parking lot and then the volume of water falling on the school parking lot. They map the route surface runoff will take to the nearest water body and describe the roles that human...

Collaborative earth science groups create a working model of a watershed. Once it has been developed, you come along and introduce a change in land use, impacting the quality of water throughout their watershed. Model making is an...

Students define surface water, drainage basin or watershed. They investigate what affects runoff in a drainage basin. They complete lab sheets and worksheets.

Students explore the components of a watershed and the factors that affect it. They read a topographical map and use geometry to determine the area of a watershed. Students estimate the volume of a body of water and perform runoff...

Learners recognize that all of the water on earth cannot be used for drinking and that the percentage of ground and surface water is a small percentage.  In this water lesson students identify ways to conserve water. 

Students investigate some of the factors that determine the amount of runoff. They are reminded that infiltration and runoff tend to work oppositely. When conditions are bad for infiltration they usually lead to runoff.

Students identify the watershed where they live and how it is related to their own water consumption. In this watershed instructional activity students locate their watershed on their town map. The students find the source of their water...

Learners model a watershed and delineate one using topographic maps. In this hydrology lesson, students use aluminum foil to model a landscape and observe how water moves on it. They also observe the features of a topographic map and use...

Students conduct a study of the school grounds in order to find information about how water moves during the rainy season. They estimate the area of the school grounds and determine the route that water would take as storm runoff.

Which materials are best for groundwater runoff, and which are best for percolation? Discuss the water table with several experiments about different types of soil, pollution, precipitation, and filtration. The experiments assign...

Students use satellite images to analyze development patterns within Baltimore City. They prepare a land cover map for Baltimore indicating the prevalence of impervious surfaces and explore how these patterns affect water pollution.

Students study groundwater movement beneath the surface of the Earth. In this agriculture lesson, students experiment with how water moves through rock materials such as sand, gravel, and clay.

Students examine, through demonstration and experimentation, how water moves through watershed, identify pollutants that can enter water system from different land use activities, and discuss ways people can help prevent water pollution.

Students examine the major paths of water on the Earth's surface, and to investigate the many factors that contribute to those paths. Students demonstrate their understanding of a watershed by identifying the defining features of a...

Students examine urban runoff and identify peak flows. They examine causes for different flow rates, and complete worksheets and a graph.

Young scholars study urban runoff. They identify the urban runoff in a simulated area and determine peak flows using charted data. Finally, they discuss possible causes of the differences in flow rates.

Students examine human impacts on the water cycle. They compare/contrast the permeability of various materials for the purpose of engineering landscape drainage systems, and answer discussion questions.

Students list and describe three types of surface water pollutants. They observe the effects of various water pollutants on algae growth. Three causes of each surface water pollutant is listed.

Students examine the relationship between land development and the environment. In this environmental stewardship lesson, students explore how population density, land development, transportation, and impervious surfaces take their toll...

Students define watersheds, ground water and nonpoint source pollution. They describe how rainwater moves on the surface, as well as underground, as part of the water cycle. They recognize what flooding is as well as its causes.

Young scholars construct a water table elevation contour map and consider the direction and rate of groundwater flow to predict the actual runoff pattern. They discuss their findings and evaluate a hypothetical landfill site based on...
