Straining out the Dirt

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...

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...

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...

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...

Before your learners excuse themselves to get a drink at the water fountain, prompt them to think about where that water comes from. A middle school science instructional activity encourages groups to research their community's source of...

Open learners' eyes to the challenge of finding safe drinking water – something we often take for granted in our country. The PowerPoint presentation includes images, graphs, diagrams, and even a video to stimulate discussion on how we...

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...

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.

Take a field trip with water as it moves on and below Earth's surface. Investigators discover the link between water and land in the water cycle and the importance of watersheds while viewing an animated video. Scholars test their...

Examine water as a scarce natural resource instead of taking it for granted. Middle schoolers identify the traits of potable water, and research local water sources to determine if they are impaired or not.
