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...

Young scholars investigate water pollution. They develop an understanding of the behavior of organisms, of the structure and properties of matter, and of natural and human induced hazards by conducting lab tests. They present their data...

Sixth graders design experiments to compare the amount of bacteria in river water to the amount in purified tap water. They explore how water purification removes bacteria and pollution from the water. Students examine the steps of the...

Divide your chemistry or environmental science class into two groups. Each group tests water samples from a river for the concentration of phosphorus using a different method. With chemists, you can use this activity as they learn to use...

Students identify possible sources of health risks, types of exposures, routes of exposure, and populations that could be affected after discussing water pollution and environmental health hazards. After discussion, students conduct a...

Introduce the topic of water conservation with a little drama. Dressed as snowflakes, hail stones, or rain drops class members dramatize the events in a narration of the water cycle. The series of lessons that follow focus on...

Young scholars 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...

In this water pollution and filtration lesson plan, 5th graders read the story 'Saving Salila's Turtle' and discuss the impact pollution has had on the Ganges river. Students work in groups to brainstorm different types of water...

Learners construct a model of the hydrologic cycle, and observe that water is an element of a cycle in the natural environment. They explain how the hydrologic cycle works and why it is important, and compare the hydrologic cycle to...

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...

Young scholars explore how sewer systems can contribute to water pollution and perform an experiment to see how well a water purification technique can protect against water-born microbial illnesses. They compare the bacterial growth...

Students investigate how pollution affects lung health. In this pollution and lung health lesson, students build lung models from a soda bottle and balloons, and then discuss how the emissions from fossil fuels can adversely affect lung...

Sixth graders are able to explain that there are pollutants in the Anacostia River, what these pollutants can cause, and how to prevent further pollution. They examine the impacts that the pollutants of the Anacostia River could have on...

A professional and comprehensive presentation on Chesapeake Bay water quality is in store for your ecology class. If you live in the Chesapeake Bay region and want to get learners involved in conservation efforts, this slide show will do...

The surge in human population in the last 2,000 years, due in large part to better health care, has brought a surge in the demand for resources and in pollution. The graphics, photographs, and real-life examples in a thought-provoking...

After a whole-class discussion of water reservoirs, ten liters of water are given to each lab group to represent Earth's total amount of water. They divide the water into smaller containers, each representing one of those reservoirs. The...

Written as field trip preparation to Gateway National Recreation Area, this resource is also appropriate for any class that is studying the impact of human activity on the environment. During the first activity, learners identify...

Middle schoolers debate one another. In this pollution lesson, pupils work in teams to debate which is more serious, air or water pollution. They research their topic to come up with valid points to justify their side of the debate.

Fifth graders conduct experiments in simulated water pollution using a box of items to hold "pollutants"and an aquarium, representing a waterway. They observe how "rain" from a watering can poured into the box washes the pollutants into...

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

Students examine potential contamination on the environment due to products and by-products of a new industrial process. Students conduct a lab that explores the economic differences between choices of pollution cleanup and prevention.

Scientists listen to the story of Wadja Egnankou who works to save African mangrove forests. They experiment with refraction and the introduction of particulate matter to water. They conclude with creative writing about the need for a...

A scenario and background information are provided for two different open-ended experiments that experienced chemistry classes can perform toward the end of the school year. In the first, they design a method for testing flakes of paint...

Students investigate the concept of safety in and out of the water. They conduct research using a variety of resources. Students focus upon the role of police officers in the keeping of safety and then discuss the different types of...
