MadSci Network: Chemistry |
I am a former middle school science teacher working on my Ph.D. in science education. I would like to learn more about water quality testing, specifically testing for dissoved oxygen, carbon dioxide, phosphates, nitrates, and coliform bacteria. Most of the lab activities I have seen must be used in conjuction with some type of comprehensive kit that schools must purchase but that doesn't actually describe what chemicals are used in each experiment. I would like to learn how to perform quantitative tests for the above by purchasing my own chemicals rather than spending hundreds of dollars on a commercial kit.Can you tell me what chemical procedures can be conducted to test for the above with middle school students?
