DIY – Water Quality
Students can build their own deep water sampler to allow them to capture water samples at depth for subsequent testing. This tool is great for comparing water quality between surface and deep water quality samples.
"Students will have fun analyzing sample water for eight different test factors: pH, dissolved oxygen, biochemical oxygen demand, temperature, turbidity, nitrate, phosphate, and coliform bacteria. This complete kit includes a manual with step-by-step, diagrammed instructions; an easy-to-use laminated color chart, and all the necessary apparatus and non-hazardous TesTabs® to test ten water samples (three samples for coliform)."
