My students loved this water quality lab. On Day 1, I had four mason jars filled with water samples taken from our community (tap water, river, creek, and public/outdoor fountain). The bulk of the learning came from their interactions during the lab and the class discussion we had after the lab. We discussed clarity, sediments, pollution, and more!
The students learned about the sources of pollution and they realized that every one of us can do our parts to make our Earth cleaner.
