Day 11: Make a Watershed!Day 11: Make a Watershed!Make your own model of a watershed.<div class="ExternalClass31C891DB476F49099BC064B6AFD5971D"><div>To learn how to be a wise watershed manager, you must have an understanding of how water travels on a watershed. A watershed is a land area through which water drains to a low point. Follow these directions to create your own watershed.​<br><div><ol><li>Gather materials: a spray bottle with water in it, washable markers (red, blue, black, brown, and purple colors), a roll of tape, and two sheets of blank paper per person.<br></li><li>Take the first sheet of paper and crush it into a ball. </li><li>Gently unroll the ball of paper and place it on the other sheet of paper to form a mountain. Tape the four corners of the "mountain" down on the flat sheet of paper, which is the land.</li><li>Trace the ridges and mountain peaks of your model with your finger. The note the creases in your model - those the low points where water will travel. </li><li>Now, add color to your model. Carefully trace the tallest mountain peaks with black. The black will represent snow that falls on our mountain peaks.</li><li>Carefully outline the creases with a blue washable marker, to represent rivers and streams.</li><li>Now, build on your watershed using the other washable markers by adding cities using w (purple hashtags #) and farms (brown rectangles). Add potential pollutants, such as trash, old mines, pet waste, or an old car leak*. You can add these anywhere you'd like on the model. You are making decisions about how land is used.</li><li><p>Finally, take the spray bottle and make it rain on your model. You may want to place your model in the sink or outside. Watch the flow of the river. Note any movement of potential pollutants. Discuss and write in your Science Notebook if you would change your land use plan based on what you observed.<br></p></li></ol></div></div></div> 7:00:00 AM
