Ecology candidates culture pond water organisms over a few days time, then they experiment to find out how increasing nutrients affects the population. As part of a unit on water, this exploration gives your class an understanding of how...

Students become aware of pollution in Richfield Minnesota's Wood Lake, identify sources of pollution in Wood Lake, learn to use variables, equations, spreadsheets and modeling software, and generate solutions for the problem.

Students observe the effects of pollution on living organisms. In this pollution lesson plan, students observe fresh water Hydra and look at their structures and movement. They place samples of pond and lake water on the Hydra and...

Students examine how to conserve water. They also discover how to prevent water pollution. They examine the Earth's water distribution as well.

Students explore techniques used to filter water and different pollutants. In this prevention of water pollution lesson plan, students define water pollution and list ways water is polluted. They explore water purification and complete a...

Students use determination of dissolved oxygen and water temperature changes to determine the environmental impact from thermal pollution.

Young scholars take samples from local freshwater sources and examine them for macroinvertebrate life. They take samples from both shallow and deep freshwater environments, measure temperatures, and classify organisms found in their...

Fifth graders investigate how humans pollute the water supply with a number of different contaminates. While working in small groups they examine screening, sedimentation, filtration, and chemical treatments as methods of water treatment.

The introduction to the lesson mentions a sailor's limited capacity to store drinking water on his ship. Pupils then set up an overnight experiment to remove freshwater from salt water by distillation. There is a math and map activity to...

Students complete a unit on the effects of pollution on our water supply. They create a graph to examine the density of earth's land surface, round the population to the nearest hundred million place, participate in a...

Students create a model of a salt marsh to discover the impact of pollution and human activities on water-based habitats including bays and the ocean. They recognize the relationship between natural and developed areas. Students impact...

Students explore the concept of water pollution. In this environmental stewardship lesson, students discover what watersheds are and consider how to protect them.

Students explore how pollution and invasive plants disrupt the ecosystem.  In this restoration lesson plan students list materials that pollute wetlands, how people can keep them clean and ways in which invasive plants establish. 

Fourth graders construct their own aquifer. They discover how water travels underwater and identifies sources of underground pollution. They record their observations and discuss the results.

Fifth graders explore how the tow islands receive and use fresh water. They also address some of the threats to the fresh water supply on each island. Students explore the lesson objectives through water cycle models and experiments.

Students explore what a food web is. In this science lesson, students examine how nutrients and other pollutants enter a lake and play a food web game whereby students pretend they are either zooplankton, planktivore,...

Students examine effects of an oil spill on birds and animals that inhabit marine or freshwater ecosystems, and simulate procedures used by rescue workers who rescue and rehabilitate birds and other animals coated with oil.

Students investigate the amount of fresh water on earth and which water can be used for consumption. For this fresh water lesson plan, students calculate the amount of fresh water that can be used for consumption on earth. They use a 5...

Fourth and fifth graders explore soil by taking a simulated field trip under the earth. They go to an Internet site that runs a simulation which charges them with finding a source of pollution that could destroy all of Earth's soil, and...

Students become familiar with the water cycle and water issues.  In this water lesson students examine what they can do to protect their water.

Students use a light microscope to observe the organisms living in a sample of ocean or fresh water. Students create a drawing of the organisms that they observe. Students then discuss the different body plans of the organisms and the...

Learners study the structure and habitat of the hydra in this lab lesson. Students determine if the hydra can be used as an indicator to detect pollution from automobile exhaust.

Students collect water samples from local freshwater sources and test for pH, dissolved oxygen, nitrates, macroinvertebrates, phosphates, and coliform bacteria in order to determine water quality for each source.

Field study groups collect samples of stream water and identify the macroinvertebrates found. Using their data, they calculate a water quality index to rate the health of the stream. They graph their data and discuss the value of a water...
