Rubric for evaluating students’ watershed drawings Watershed concept 2 1 0 flow on the surface The image shows that elevation divides bodies of water and water flows downhill. Image shows that water flows downhill or elevation divides bodies of water. Model does not show water moving on elevation. Watershed boundaries The image shows that elevation serves as a boundary for watersheds. The images show that watersheds have a boundary, but no relationship to elevation is shown. The image does not include a boundary. Nested systems The image describes and shows that watersheds are nested within other watersheds. The image shows or describes that watersheds are nested within other watersheds. The does not show nested watershed systems. Inputs The image shows multiple sources of water within the watershed. The image shows one source of water within the watershed. The image shows no sources of water. Outputs The image shows water flowing into a body of water (stream, river, or lake) from the land surrounding that body of water. The image shows water flowing from part of the land surrounding a body of water, or part of the body of water with water flowing from all of the land that serves as its source. The image does not show a relationship between land and a body of water. Energy/gravity The images describe and show that gravity is a force that moves water from high to low elevation. The image describes or shows that gravity moves water from high to low elevation. The image does not include reference to the role of gravity in the movement of water.
