Comparative Stream Quality

How does dirty water get clean enough to drink? After viewing a PowerPoint that outlines the process water goes through at a water treatment plant, groups work together to design a chlorination chamber for a treatment plant.

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...

Is the golf course causing issues in the stream? Find out with a resource that has groups perform chemical water tests to analyze the effects of a golf course on a stream. Pupils collect water above and below the course and analyze the...

Learners construct a model of the hydrologic cycle, and observe that water is an element of a cycle in the natural environment. They explain how the hydrologic cycle works and why it is important, and compare the hydrologic cycle to...

Dive into a lesson on the hydrosphere with this Powerpoint presentation. Building on prior knowledge of the water cycle, young scientists learn what happens to water after it falls as precipitation and explore the...

What are the issues surrounding water quality? Viewers of this short presentation gain information about the importance of clean water, the lack of fresh water, water contamination, and ways that engineers treat water. 

The City of Winnipeg water treatment plant is a state-of-the-art, modern facility designed for performance, safety, and environmental sustainability. Take a virtual tour of the plant to see how this amazing technology ensures safe...

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.

Water that leaves the oceans must eventually return. The animations in the final lesson of the four-part NASA series show the complex path water can take across landforms before returning to the ocean. Approximately one-third of the...

Students investigate many of the factors that affect water quality. They take measurements and water samples at a local stream and evaluate the health of their community's watershed. They write a report detailing their findings.
