It's easy to forget about something as simple as water, a substance that is easily available to many in the world. However, understanding water management and the importance of a renewable resource system becomes clear in an informative,...

How important is water quality where you live? The first module in a six-unit series includes four lessons on water quality. By applying the concept directly to the lives of pupils, they engage in meaningful learning. They read about...

What are the issues surrounding water quality? Viewers of this short presentation gain information about the importance of clean water, the lack of fresh water, water contamination, and ways that engineers treat water. 

As a follow-up from the previous activity, young environmentalists discuss the benefits of water filtration and whether or not it's the best option. Other alternatives including air stripping, bioremediation, and phytoremediation are...

A wrap-up to the unit, young environmentalists discuss and write about the difference in perspectives of a water keeper and water treatment engineer. 

How much is too much nitrate in the water? Young scientists discuss the question after they run their own nitrate tests. They also consider sources of nitrates and offer explanations for the levels.

Sometimes solving one problem leads to another. Scholars respond to questions about fracking to harvest natural gas and other environmental related topics. The resource provides items released from the 2012 AP® Environmental Science exam...

These small particles have a huge job. A poster shows future engineers an application of nanotechnology. It describes how nano silver particles are embedded into plastic water barrels to help kill E. coli bacteria.

How do you prevent the spread of water-borne illness in large public swimming areas? Scholars discover the challenges to identifying safe water through an inquiry experiment. They then produce posters sharing their understanding of water...

Good things come in small packages. A four-lesson unit plan provides educators with a framework for teaching about nanotechnology. The lesson looks at how nanotechnology relates to water purification, cancer treatment, solar energy, and...

Water is essential for life—and understanding the importance of clean drinking water is essential in understanding sustainability! Show your environmental science class the basics of water testing and treatment through a week-long...

How can we stop the tiny terrors that cause illness? Junior epidemiologists examine the methods used to control the spread of pathogens with a video from from a biology playlist. The narrator describes the benefits of hygiene,...

How safe is the drinking water you have access to? Colors, smells, and other factors may lead you to finding out if your water is safe. Watch a video that explains the ways water becomes filtered and ways to know when water is contaminated.

To flush or not to flush ... that is the question. Is the wastewater treatment program in most towns and cities really the most efficient way to deal with waste? The fourth installment in a series of seven videos about the world's water...

Develop a model of a wastewater treatment center. The last activity of the unit has pupils mix a lake water sample into a tank of water containing fertilizers. Over time, the algae from the lake water grows and removes the nutrient-rich...

Water pollution is everywhere, and pollutants range from oil to fertilizers. Bring the concept to life by demonstrating the difficulties in getting particular pollutants out of water.

What makes a watershed? What are the natural and human features of a watershed? How do human features affect watersheds? Where can I find my local watershed? These questions are thoroughly explained in an informative watershed interactive.

How does the dirt get out of your drinking water? A hands-on activity introduces the use of flocculants to help clear solid particles out of water. The plan walks learners through the process of setting up an experiment that controls the...

Join the tree house detectives in learning about the processes of the water cycle, water conservation, water treatment, and water as a limited resource.

How do we clean up oil spills and other pollutants in the water? Explore water treatment strategies with a set of environmental science experiments. Groups remove oil from water, work with wastewater treatment, and perform a water...

Environmentalists turn into engineers! Your class explores the perspectives of an engineer and water keeper, including the necessary steps that are taken in order to build a water treatment facility.

Explore soil, genetic traits, natural resources, and pollution in a series of lessons that focus on biodiversity. Kids complete experiments to learn more about the importance of varied genes and organisms in an ecosystem.
