Investigate the amazing ability of plants to filter contaminants from water with this series of in-class demonstrations. After placing six small, potted plants in plastic cups, different solutions and mixtures are poured into them that...

Can the class think like the scientists on the International Space Station? Engineers design, test, collect data, and improve a water filtration device similar to a system found on the ISS. Participants use pH strips, optional...

Scholars build a simple filtration system to remove impurities from muddy water and rate the filtered water to a grade of clarity scale. The focus is on teamwork and problem solving. This instructional activity would be effective in your...

Students create an all-natural water filtration system. In this lesson on natural water filtration, students build upon prior knowledge to build a filtration unit made of plants, soils, sand, pebbles and rocks that can purify...

Students build a water filtration system. In this water quality lesson, students work in groups to construct water filtration units that can purify contaminated water. This lesson is part of a larger unit on water quality.

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...

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

Students demonstrate the four of five procedures that municipal water plants use to purify water for drinking. A water filtration system is designed by a student and their partner. A data chart is made to record all observations when the...

As an example of nature's water filtering system, young ecologists conduct an experiment in the lab. They construct a funnel out of a plastic bottle, fill it with specified layers of materials that simulate layers of soil, then run muddy...

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...

Water filtration — that's pure genius! Groups test the ability of a water filter to purify water by running chlorine contaminated water through a filter and measuring the chlorine concentrations as they filter the water. They then graph...

Students design a filtration system using three filtration materials.  In this water filtration lesson, students conduct an experiment with their filtration systems.  Students present their systems to the class. Group results...

Young scholars study the process of water filtration in a three-part STEM lesson. After analyzing samples of dirty water, teams design and build their own filtration systems and measure their efficiency.

Should you trust the water you drink every day? The hands-on activity has scholars test water from different sources for contaminants. Pupils perform chemical testing and make conclusions about pH, hardness, iron, chlorine, lead,...

Young scientists explore nature's water treatment plants in this simple science demonstration. By placing a stalk of celery in a cup of water mixed with food coloring, children are able to observe how plants absorb nutrients and...

Here is a fantastic experiment-based lesson on water conservation, waste, and filtration. The lesson plan is well-developed and provides background information, discussion leads, and six scripted lab activities anyone can do. The class...

Drinking clean water can be taken for granted. Explore the process and high cost of filtering water with a water pollution and filtration activity. Young scientist build a filtration system to filter polluted water, examine the economics...

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...

Learners design water filtration systems. They draw sketches and write paragraphs about their systems. After presenting their systems to the class, each group then builds their system and determines its effectiveness for purifying...

Students construct a water filter. In this engineering lesson, students discover how to construct a water filtration system. Students work in groups to sort tools by their properties. Students analyze and construct a water filtration...

Sixth graders explain how soil and plants effect contaminated water in nature.  In this filtration lesson plan, 6th graders work in groups to test biofiltration units. Students determine which biofiltration units work best and how...

Students examine water samples assess the quality of each sample by examining the color/clarity, smell, pH, etc. of each Then they filter the water samples once and assess water quality a second time. finally they filter the samples a...

Auntie Litter is here to educate young scholars about water pollution and environmental stewardship! Although the 15-minute video clip is cheesy, it's an engaging look at the water cycle and conservation. Learners start by illustrating...
