Making a Water Filter

From their sweat to the water vapor in their breath, astronauts recycle every possible drop of water while in space. After watching a short video describing the different ways materials are recycled and reused in space shuttles, young...

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....

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...

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 filtration...

As a follow-up from the previous lesson, 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...

Sixth graders investigate the various types of pollutants found in water and ways to help prevent water pollution. Through a hands-on experiment, students create samples of polluted water by mixing water with vegetable oil, dirt, and...

Curious physical scientists follow a activity on the properties of water with this activity on distillation. They observe a miniature water cycle model that filters dirty water into clean water. These two lessons combined are an...

Fifth graders investigate the process of water treatment. They listen to the book, "The Magic School Bus Visits the Waterworks," design a plan for a water treatment system, construct a water filter using various materials, and test the...

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 in...

Here is a fine activity for fifth graders that will give them an idea of the variety of impacts that human-introduced pollutants have on the environment. After an initial class discussion and teacher-led demonstration, pupils brainstorm...
