Lesson 7: Considering the School-Pond System

How did the pollutants get into the pond in the first place?

Properties of certain types of matter (pollutants) cause them to be problematic in water systems. Pollutants (matter) that are soluble can enter waterways and travel some distance. We can scale up our model to show how pollutants and water travel in the larger system around the school and the pond. We can use our understanding of the particulate nature of matter and properties of matter to predict and explain what pollutant is in water.
