Students determine that delivering clean, fresh water to citizens around the world involves and affects politics, economics, international relations, and technology. They brainstorm a list of factors that might affect their town's...

Students study the benefits of estuaries. They construct a saltwater food web, and complete worksheets and a quiz.

Students visit a local creek or stream. They collect water samples from the creek and observe and sort the "water critters" they find in the sample, observing smaller organisms under a microscope if necessary. They identify each organism...

Students examine the effects of nitrates and phosphates on the dissolved oxygen levels in different water sources. In this series of 3 lessons, they consider the reasons for nitrate and phosphate level increases and their effects on...

Students build a soil erosion model to study the importance of soil conservation. They investigate how land forms from both constructive and destructive forces.

Students describe different types of water pollutants. They complete experiments in which they observe the affects of water pollution on algae. They also brainstorm and list three causes of each water pollutant.

Learners make a clay model and a geographic map of a watershed. They talk about the differences between the two representations and the potential human threats to watersheds.

Students investigate the environmental problems that surround the Chesapeake Bay area. They use an environmental handout as a resource that should be supplemented with research. Also students ask specific questions to report findings and...

Students measure the pH of local rain water. Students map the location of the collected rain water according to pH levels.

Students experiment with a simulated river bed and examine how erosion takes place faster with a young, fast-moving river than with a slow, older river.

Students understnad the importance of keeping our rivers and streams pollution free by remembering the major rivers of northeast Kansas. The see how the rivers contain particles of every substance that drains into them.

Students understand the connections among people, places, and environments in the local school and community, Kansas and its surrounding states, the U.S. and its region, and the world.

Students explore conductivity and productivity in aquatic systems.

Students are led through three activities to explore the effect of temperature fluctuations on the growth and survival of aquatic plants, clams, and shrimp eggs.

Eighth graders examine the components of a watershed. They view overheads, discuss the hydrologic cycle, and observe a demonstration of a soil erosion box.

Learners define the terms estuary and watershed. They conduct an experiment to determine the density differences between fresh and saltwater. They examine the salinity distribution of the Peconic Bay Estuary.

Students examine the pH level of rain water in their local community. They locate each location on a map. They analyze the data and draw conclusions.

Young scholars study the Exxon Valdez Oil Spill while evaluating oil spill clean up activities. They discover the long term impact can have on an ecosystem by completing this experiment.

Young scholars discuss the topic of streamflow and how it occurs. They take measurements and analyze them. They interpret data and create their own charts and graphs.

Students identify at least three common repercussions of developing water front property on water quality. They describe three sources of water pollution. They research the organism striped bass and observe it if striped bass is available.

Young scholars discuss the benefits of water conservation. Given a data sheet, they document their water usage over a specified period. Water usage data is graphed and analyzed. Students discuss ways in which they can conserve water.

Learn about the different stages of the Earth's water cycle, and about processes involving water, including runoff, infiltration, and the differences between hard and soft water.

[Free Registration/Login may be required to access all resource tools.] Discusses how flowing water causes erosion; describes how runoff, streams, and rivers change Earth's surface; and identifies features caused by groundwater erosion.

[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.
