The USGS Water Science School
This is the interactive section of our site where you can answer challenge questions, participate in opinion surveys about water issues, and take true/false quizzes. For most of the activities, your answers will be entered into a data base and, after answering, you'll be shown a table of how those in other states and areas of the world responded. You can hit Submit and view the responses even if you don't take the surveys.
