What do you think a watershed may be by hearing the name? Lets separate it, water and shed (shed: keeps things) watershed: think of :Land that holds water Watershed: Is anywhere on land, that what happens to the land, ends up in a large body of water. (Lake, reservior,or ocean) Streams from the top of mountains join together and form rivers, rivers run into a larger bodies of water that people rely on for drinking or eating and swimming.

Did you know all of R.I. is considered a watershed area? Anything that happens in R.I. eventually ends up in Narragansett Bay. How? We will explore with the watershed model.


 * Watershed model**

Have students tell you what you would find in RI. As they name things let them place it on the watershed model. Prompt them with questions about what type of pollution you would get as a result from each place? The add in pollution type on the watershed model

Farm animals, droppings pesticides/herbicides (red glitter) roads cars oil-(vegetable oil with black food coloring) houses herbicides on lawns (green glitter) trash (sprinkles) factory pollution, chemicals (silver glitter) sewage treatment plant (brown water)

After everything is placed...

Take the buildings off and objects off of the land sample and leave only the pollution. Spray the squirt bottle over the entire watershed representing rain that is falling on the land. Take note of the direction that the water is flowing. Notice that all of the water eventually ends up in the ocean. What happened to the pollution? Where did that end up as well?
 * // Let it rain! //**

Can anyone think of a way to clean this up and get the clear water back?

What are ways that we can stop pollution? How can we educate others of the effect that pollution has on our water and how it eventually affects us? What course of action much be taken to prevent as well as clean our water?
