Young scientists explore nature's water treatment plants in this simple science demonstration. By placing a stalk of celery in a cup of water mixed with food coloring, children are able to observe how plants absorb nutrients and...

Students examine runoff for the causes, the impact, and the solution.  For this investigative lesson students construct a three dimensional model of a watershed and provide information of contaminated runoff to their audience. 

Young scholars conduct an experiment to show how water gets contaminated through neighborhood runoffs.

Students examine how a sanitary landfill is constructed, how it functions, and how waste and leachate affects the areas around the landfill. After a discussion about landfills and leachates, students construct a Sanitary Landfill Model...

Students examine how mining and other industry operations can lead to acid runoff.  In this mining lesson students study weathering and complete a lab on it. 

High schoolers write out sources of pollution and identify contaminants are most likely found in urban runoff.  In this pollution lesson students compare toxicity tests and chemical analysis of potential contaminants. 

Students 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 data...

Young scholars investigate the San Francisco Bay Estuarine Research Reserve and watershed. In this estuary and watershed lesson plan, students complete 4 activities to better understand estuarine systems. They include studying the San...

In a series of lessons, examine the impact on humans by microcosms in the biosphere. Among the plans structured for students with different abilities and learning styles, are activities describing the symbiotic relationship, drawing the...

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...

Learners 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 build a model that depicts how water is stored in an aquifer. They examine ways in which groundwater can become contaminated.

Pupils explore sources of  pollution runoff and actions that can be taken to reduce runoff.  In this pollution lesson students complete a worksheet and see why bio-essays may provide a more realistic picture of toxicity.

Students develop an awareness of what happens to water contaminated through neighborhood runoffs. Students perform an experiment that shows what happens to runoff when it's diverted to different places.

Pupils discover how wetlands filter out contaminants before they can reach other bodies of water. In groups, they design and build a model of a stormwater wetland. They test the water quality and inform their classmates about the...

Pupils explain the basic properties of a watershed including how water flows from higher to lower elevations and how watersheds are interconnected. They comprehend how the placement of buildings, roads, and parking lots can be important...

Eighth graders examine how humans affect various ecosystems. In this ecology activity, 8th graders discuss different ways that contaminants enter the stream. They explain the consequences of eutrophication in lakes.

Sixth graders investigate the various types of pollutants found in water and ways to help prevent water pollution. Through a hands-on experiment, learners create samples of polluted water by mixing water with vegetable oil, dirt,...

Students study non-point source pollution. They research the concept of bio-degradation and/or Nutrients/Fertilizers and discuss how non-point source pollution impacts the environment. Afterwards, they participate in an interactive...

Livestock managers reinforce math and science skills while learning about the nutrients found in manure. They predict which animal produces the largest amount and which animal's manure contains the most nitrogen. Finally, they compare...

Students list causes of water pollution, discuss how people contribute to water pollution, and explain concept of watershed.

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.

Discuss the availability of clean, plentiful water and the causes of water pollution. In groups, sixth graders discuss problem-solving methods for keeping water clean. They explore the function of water treatment plants and perform...
