These materials are part of a collection of classroom-tested modules and courses developed by InTeGrate. The materials engage students in understanding the earth system as it intertwines with key societal issues. The collection is freely available and ready to be adapted by undergraduate educators across a range of courses including: general education or majors courses in Earth-focused disciplines such as geoscience or environmental science, social science, engineering, and other sciences, as well as courses for interdisciplinary programs.

For the Instructor

These student materials complement the Water Science and Society Instructor Materials. If you would like your students to have access to the student materials, we suggest you either point them at the Student Version which omits the framing pages with information designed for faculty (and this box). Or you can download these pages in several formats that you can include in your course website or local Learning Managment System.

Formative Assessment 1: Watershed

Instructions

For graphical questions, create and print a legible diagram according to the specific guidelines given (Questions 1, 3, and 4). For short answer questions, answer each question in 2-3 complete sentences (Questions 2 and 5). Consider each question carefully and be sure to provide a complete answer.

Questions

  1. You live in a watershed...or more likely multiple watersheds that are nested within one another. Find the location of your home on Google Earth (or a similar mapping program) and determine which watersheds you live in (e.g., Saucon Creek watershed, which is part of the Lehigh River watershed, which is part of the Delaware River watershed). If a drop of rain hits your front yard, which stream would it flow into? Where does it go from there? For the purpose of this exercise, assume the water runs off the surface and ignore the (likely) possibility that it goes into a storm sewer and waste water treatment plant before being discharged into a local stream or river. Use the exaggerated 3D view of Google Earth (Tools>Options>3D View, then set Elevation Exaggeration to 3) to see the local topography. Use the 'Add polygon' tool (in the tool bar along the top of the viewing window) to delineate the watershed boundary of the stream that your property drains into (should look something like Figure 1 below). Note that when you are finished drawing the polygon, you can name it (it will automatically save in My Places in Google Earth) and you can change the color of the watershed boundary and the opacity of the fill (make it 50% so you can see through it). Grab a screen shot of your watershed delineation.
  2. Describe the watershed you live in and which larger watersheds it is nested within (see example below).

  3. Take a look at the cartoon watershed drawn below.
    1. What is the stream order at the mouth/outlet of the watershed?
    2. Draw arrows on the watershed cartoon to illustrate each of the fluxes shown in Figure 5 on the previous page.

    3. Draw a second version of your watershed cartoon and scale the thickness of the arrows to illustrate which flow paths might become more dominant (i.e., pathways conveying more water get thicker arrows) following a clear-cut for timber harvest or urban development.
    4. Explain why certain pathways have become more/less important after clear-cutting the forest. Bring this figure and explanation to class for comparison to the figure you generated for Question 3 above.
