Unit Overview 

Keeping the water supply clean is everyone's responsibility for the common good. Learners practice core democratic values, explore literature through the book A River Ran Wild, follow the path of pollution in a river, focus on the concept of one million, and use the scientific method to examine the water cycle. They take action to address the issue of water pollution.

Service Experience 
Students take action to address a pollution issue locally. They may take direct action, such as picking up trash or advocate for a water quality issue. They may do original research and communicate their findings and propose a solution.

Learners will develop a graphic way of visualizing the concept of a million by utilizing what had happened to the Nashua River due to the dumping of raw sewage in 1962. In the first class period, the learners will be introduced to the concept of a million by creating containers that will hold a million small items (i.e. grains of rice). In the second class period the learners will create a model of the Nashua River. Using the concept of a million from the previous class period, they will see what happens to this river by simulating the action of dumping raw sewage (i.e. grains of rice) into our model of the Nashua River.
