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...

Using the polluted water that was made in the prior lesson, your young environmentalists will mix pollutants together in an experiment. Then, they will design a water filter that will clean the polluted water to use in the next lesson....

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....

Teach young environmentalists to protect their planet's resources with a set of interactive experiments. Kindergartners and other youngsters learn about watersheds and the water cycle, while older elementary learners focus on fertilizer...

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...

How is it that water that falls as rain ends up coming out of the tap on our sinks? Learners trace water's journey and examine how along the way pollutants make their way into the water supply. They conduct experiments, use the Internet...

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...

Give young scientists a new appreciation of fresh, clean drinking water. After learning about the ways astronauts recycle their air and water, your class will work in small groups creating and testing their very own water...

See the water filtration system up close with a fun science experiment. Young scientists work for several class periods to design a water filter using household objects, and then decide which filter material would be most effective...

Whether you are teaching environmental science in junior high or studying recycling in kindergarten, there is something for all in this set of lessons designed for environmental education. The 110-page packet comes with tips for...

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...

You've heard of farm to table ... but what about farm in classroom? Junior agriculturalists embark upon a two-week journey into the science of growing things. Based upon the classic terrarium in a two-liter experiment, the instructional...

Demonstrate to your middle school science learners how chalk breaks down in a weak acid. Discuss what affects acidic rain might have on ecosystems. Lab groups then choose one of two questions: "How does acid precipitation affect an...

The lessons in this learning guide are designed to increase youngsters' awareness of the impacts of marine debris and to teach them about pollution prevention techniques. This fabulous, 30-page packet is chock full of important...

Intended as a follow up to the Protecting Your Drinking Water activity, young environmentalists use their assessment of the a hypothetical town's water supply to debate the installation of underground chemical storage tanks. With...

That is living in the water? Groups of two to three view pond water with microscopes in order to find microorganisms. They draw pictures of the ones they find in their slides.  The groups compare their drawings to pictures of common...

Model an oil spill cleanup. An engaging engineering lesson has groups using aerogels to simulate an oil spill cleanup (vegetable oil in water). Along the way, they learn about nanotechnology and hydrophilia/hydrophobia.

How does carbon dioxide affect the world's oceans? The final installment in a series of six lessons has pupils research ocean acidification, then conduct an experiment to witness the delicate balance that exists in our seas. Materials...

Now is the time to educate tomorrow's citizens to care for the planet, and here is a lesson plan to help facilitate the process. Collect some marine debris and bring it into class. Have your class separate it into types and then test...

Which materials are best for groundwater runoff, and which are best for percolation? Discuss the water table with several experiments about different types of soil, pollution, precipitation, and filtration. The experiments assign...

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.

Young scientists roll up their sleeves and get a little dirty in this three-day earth science investigation. Following the scientific method, children monitor the growth of algae in pond water samples in order to determine...

Nanofibers can be made through electrospinning or force spinning in order to reduce the negative impact on the environment. Pupils study the role of fibers and dye on the environment through a series of five hands-on activities. Then,...

Robert Hass's article "Rivers and Stories" underscores the importance of rivers in the development of civilization and the importance of reclaiming supposedly dead rivers and implementing policies that protect river health. Groups...
