Water 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...

How do you prevent the spread of water-borne illness in large public swimming areas? Scholars discover the challenges to identifying safe water through an inquiry experiment. They then produce posters sharing their understanding of water...

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...

Divide your chemistry or environmental science class into two groups. Each group tests water samples from a river for the concentration of phosphorus using a different method. With chemists, you can use this activity as they learn to use...

As the title implies, this is a list of vocabulary terms relating to water monitoring. If your ecology class is learning about how to test water quality, this will be an appropriate reference sheet for them. As a bonus, if you live in...

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 do we know when water is safe to drink? Part seven of a 10-part videos series uses water quality as a platform to explore the behavior of halide ions in solution, Further tests help learners differentiate between precipitates that...

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.

In this science worksheet, high schoolers use the diatoms present in water in order to test water quality and perform data collection and interpretation.
