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...

What's in your water? And, why is water quality so important? Enhance your class's level of water appreciation through a instructional activity that demonstrates the necessity of water quality. Environmental enthusiasts explore the EPA's...

Nanoparticles have toxic effects on plant and animal life—even though you can't see them. The second lesson of a two-part series has young scientists conduct an experiment that exposes plant and animals to nanoparticle pollutants. They...

What does it mean to be a good steward? Middle school environmentalists learn to care for their state's waterways through research, a guest speaker, and poster activity. Groups must locate and learn more about a river basin and the human...

Investigate the migration of the nanoparticle from land to water! A lab investigation asks budding scientists to simulate runoff. Testing water samples before and after the simulation leads individuals to make conclusions about pollution...

Healthy invertebrates mean healthy ponds. An outdoor activity has scholars collect samples of invertebrates from local lakes or ponds. They identify and count different species and use the information to estimate the level of pollution...

Just because we can't see it doesn't mean it isn't there! A growing concern for environmental scientists is toxic nanoparticles in our air and water. Young scholars conduct an experiment to demonstrate how these particles can cross our...

Our relationship with toxins is, well, a little toxic. Explore how harmful substances work their way throughout the environment with a video from an expansive biology playlist. Topics include DDT and mercury, trophic levels, and water...

Water, water, everywhere, but not a drop to drink—until we clean it, of course! Scholars design a filtration device that removes pollutants from water. The goal is to have the water come out as clean as possible from the device. How...

What's the best way to learn how watersheds work? Build one! Combining engineering, the water cycle, and ecology concerns, the activity is the perfect fit for an interdisciplinary unit. Teams construct a model watershed with simple...

How do scientists determine the best method for removing pollutants from our water sources? Environmental scholars experiment with pollution clean-up options to discover which are the most cost-effective, fastest, and most thorough....

What is the best way to test water quality? Using plastic bottles, scholars create monitoring sensors to test water quality. Creating three different sensors allows individuals to measure water quality at different water levels.

Chemistry to the rescue! Viewers of an informative video in the ACS Reactions series see how chemistry provided the proof of lead pollution in Flint, Michigan. They learn that there is no actual law that limits the amount of lead in tap...

Explore the process of wastewater treatment. Scholars analyze different samples of water before making conclusions about the types of chemicals in the water that leaves our homes. 

Can a sidewalk increase the amount of pollution in local streams? Scholars learn the answer to this question though research and experimentation in the fifth unit in the six-part series. Pupils study runoff, impervious surfaces, and the...

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...
