Who Polluted the River?

Lesson Description:

This activity, written by educators from population connection, a nonprofit education group based in washington DC, is designed to engage students in an interactive story to learn how, as human populations have increased and land uses have changed, many of our rivers have become polluted. This example demonstrates that, just as we each contribute to the problem, we can also each be part of the solution. The concept of stewardship could be the focus of a wonderful follow-up discussion from this activity. A list of potential discussion questions is included on the website.

  • list three ways to prevent and clean up water pollution
