Students compare the effects of water pollution on celery stalks. The class reads a play and then completes a chart that identifies various sources of pollution and their affect on living things. They identify some ways to filter water. Cooperative groups design filters to purify simulated water samples collected from fictitious parts of their community. They determine whether their filters adequately filtered the water samples.
Students identify ways various pollutants can affect living things.
