Environmentalists test stream water for temperature, pH, and turbidity. Each group shares their information and then the class makes an overall evaluation of the water quality. A slide show sets the backdrop for the teaching portion and the wrap-up discussion. It even links to a six-minute video containing general information about water. A simple and traditional activity is supported by plenty of additional resources, and saves you a bucket of time! Consider some of the other water lessons by the same publisher.
