Are you doing a stream study in the spring? Now is the time to buy aquarium test strips. I like to use the test strips to measure pH, nitrate and nitrite levels. Here are the basics for water quality study: pH, nitrates, turbidity, temperature, odor, and conductivity. You could monitor a home well, tap water, or a stream. You do NOT need expensive equipment. Start with a thermometer, test strips, and a white ice cube tray, to sort macroinvertebrates, insect larvae in the water, which are water quality indicators. Here is background information for sampling procedures, water temperature, water transparency, fresh water macroinvertebrates, and making a Secci disk to measure water transparency from GLOBE, sponsored in the U.S. by NASA. You may like to add this cloud chart as part of the science of clouds. Don’t worry if you aren’t exactly expert. You and the kids can learn together.
