Description and Teaching Materials
Student Handout for Surf Your Watershed Lab (Microsoft Word 2007 (.docx) 31kB May4 12)
Students should begin this activity with a basic understanding of what a watershed is and how/why surface water and/or groundwater becomes polluted. The instructor should review the activity with students and show them how to access and begin using the EPA Surf Your Watershed website. It takes students 45-75 minutes to complete the activity.
The activity itself requires each student to have access to the Internet.
Teaching Notes and Tips
Some students have difficulty getting started on the activity because they are not comfortable following a set of directions and/or interpreting a watershed map that covers where they live. I choose to send students out of class to work on the activity at a location of their choice, but am on hand to answer questions. I find that if I am not nearby they often solve problems on their own.
Student responses related to explaining a specific impairment and hypothesizing its source are sometimes incomplete. Remind students to name, describe, and explain the general origin of the impairment they have chosen to investigate. Urge students to add a map of the area and to identify the contamination source in their hypothesis.
