Water Quality

Will this water source support life? Small groups test the chemistry of the water drawn from two different sources. They then compare the collected data to acceptable levels to draw conclusions about the health of the source. The...

Environmentalists test stream water for temperature, pH, and turbidity. Each group shares their information and then the class makes an overall evaluation of the water quality. A slide show sets the backdrop for the teaching portion and...

Learners use litmus paper to begin to discover the qualities of acids and bases. They learn about pH by testing clear liquids for acidity with purple cabbage juice as an indicator. The video Streamkeeper, with Bill Nye, and other video...

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...

In this hands-on lesson, students will examine the labels on common household products to determine what hazardess chemicals they contain, then test less toxic alternatives to see their affects on water quality. Students will also gain...

Water is the source of life. It appears in poetry in both peaceful and torrential descriptions; it appears in earth science in its liquid, gaseous, and solid states. Combine these interpretations of our planet's most precious and...

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.

Students recognize whether one wants to drink water, swim in it, or for the health of the organisms living in it. They prepare different water samples to observe and collect samples regarding the water quality.

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.

Sixth graders design experiments to compare the amount of bacteria in river water to the amount in purified tap water. They explore how water purification removes bacteria and pollution from the water. Students examine the steps of the...
