In this experiment, students will test the quality of a water sample by observing the number of coliform bacteria. Coliform bacteria are found in human intestines and a large amount can indicate water contamination. Lesson plan gives a...

Students measure the effectiveness of water filters in purifying contaminated water. They prepare test water by creating different concentrations of bleach (chlorine-contaminated) water. After passing the contaminated water through...

Use this lesson plan to introduce students to testing water sources for pathogenic microorganisms. Students will learn methods for groundwater sampling to evaluate water quality. Lesson plan includes student worksheets.

In this unit, students will try to improve stream quality and reduce human impacts by taking action.This Advanced Water Quality unit is packaged into three smaller parts: Part 1: Stream Habitat Assessment; Part 2: Macroinvertebrate...

Online children's story that teaches about the importance of keeping water clean. Click on "next" at the bottom of the story to discover why having pure water affects the way we live and learn.

Directions for doing a simple simulation that shows how pollution spreads through groundwater sources.

This is online resource is for teachers of all grades. The Water Sourcebook contains activities grouped according to grade level. Detailed lesson plans are provided along with glossary and fact sheets.

This site reviews the effects of agricultural development, urban and industrial development, drainage of the land surface, modifications to river valleys, and modifications to the atmosphere have on ground water and surface water.

Engineers work in many fields associated with precipitation. Engineers study glaciers to better understand their dates of formation and current demise. They deal with issues of pollution transport and water yield, and they monitor...

Given a water table model, students will observe and record as pollution infiltrates the ground and surface water.

Students visit three sites to investigate the areas where there is very high sensitivity for ground-water pollution. They also test the quality of water, measuring the dissolved oxygen, pH, total phosphate, nitrates, turbidity, and...

During this research project, students will choose either the direct method or the indirect method to monitor and measure pollution while manipulating one variable. They will develop a research question to work on and present their...

Students discover how tiny microscopic plants can remove nutrients from polluted water. They also learn how to engineer a system to remove pollutants faster and faster by changing the environment for the algae.

This activity focuses on getting students to think about bacteria, water quality and water treatment processes. Students develop and test their hypotheses about the "cleanliness" of three water samples prepared by the teacher. Then they...

By looking at the bottom dwelling macroinvertebrates, students will investigate water quality and habitat quality in this field lab. Students will record the number of creatures found at the bottom of a pond, lake, ditch, stream or river...

Students will investigate three aquatic ecosystems (pond, stream, bog) to determine the relative pollution index and the water quality of each ecosystem. They will collect and analyze the benthic organisms found in each system and...

By the end of this lesson, students will understand how we can use macroinvertebrates to determine the quality of water in a river or stream.

Included here is a collection of activities to teach students about watersheds and pollution.

[Free Registration/Login Required] How can you treat the earth with more respect? Check out this resource featuring links to elementary activities to celebrate Earth Day. You will find word searches, crossword puzzles, reading...

Through this EPA resource, explore your environment and discover the animals, plants, air, and water around you. Learn how to protect the world we live in with fun games.

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.

A large collection of lesson plans on environmental topics. The lessons are broken up into the broad categories of air, water, and waste, and look at issues around quality, pollution, conservation, and recycling. There are activities for...

In this field lab, students 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...

Students design and build model landfills using materials similar to those used by engineers for full-scale landfills. Their completed small-size landfills are "rained" on and subjected to other erosion processes. The goal is to create...
