Webquest

  1. 1. Where does our water come from? By: Patrick Gardner High school Earth SciencePurpose: This webquest will be done for two reasons. The first is to review what wehave learned about the water cycle before the test, as well as make connections toour own lives. The second objective for this activity is for you to become morefamiliar with resources on the internet and asked to analyze the information, thesesites include the USGS, GoogleEarth, NASA, EPA and others.Part I: The Water Cycle: 1) This first step to understanding where our water comes from is to review the water cycle. Go to the site listed below and explore the water cycle. When you think you have an understanding of the material take the quiz (found on the lower left side of the diagram). Then answer the question below.http://earthguide.ucsd.edu/earthguide/diagrams/watercycle/Taking into account your knowledge of the Salt Lake area, where does water exist orwhat are the reservoirs of water found in the local area?In the following activities we will continues to explore the natural reservoirsof freshwater (ground water, ice/glacial, rivers/lakes, and atmospheric) inmore detail. 2) Freshwater storage: Explore the following website to understand freshwater storage (i.e. rivers, and lakes).http://ga.water.usgs.gov/edu/watercyclefreshstorage.htmlWhat are the inputs or inflows of freshwater sources?How can surface water impact human society and where we choose to live?Do you think the use of surface water a good source of drinking water? Explain.What are the disadvantages and advantages?
  2. 2. 3) In this activity we will explore ground water. Go to the following webpage and take a look around. Pay particular attention to the diagrams. Then answer the following questions.http://pubs.usgs.gov/of/1993/ofr93-643/What is an aquifer?What conditions need to be present in order for rocks make a good aquifer? Whattypes of rocks are these?Do you think the use of ground water a good source of drinking water? Explain.What are the disadvantages and advantages? 4) Now explore the following webpage to learn about glaciers:http://ga.water.usgs.gov/edu/earthglacier.htmlWhat are the major types of glaciers?Explain the effect glaciers can have on the landscape?Do you think the use of glacial water a good source of drinking water? Explain. Whatare the disadvantages and advantages? 5) The next webpage provides information about water found in the atmosphere. http://ga.water.usgs.gov/edu/watercycleatmosphere.htmlWhat is the percentage of freshwater found in the atmosphere?
  3. 3. How does water move from the surface of the earth to the atmosphere. And how isthis water then transferred back to the surface?Do you think the use of atmospheric water a good source of drinking water? Explain.What are the disadvantages and advantages?6) To summarize what we have learned about the water cycle, I would like you tocarefully read the following article. Finally, write a healthy paragraph (4-6 sentences)relating the water cycle to your life.http://earthobservatory.nasa.gov/Features/Water/Part II: Drinking Water 7) The following website gives information about the sources of drinking water.http://cec.vcn.bc.ca/cmp/modules/wat-sou.htmWhat are the three major sources of water?How do these relate to the water cycle?
  4. 4. How is the water captured in each one of these sources?In the next section we are going to learn where the water in salt lake comes from.Before we do that take a guess. Where do you think your drinking water comesfrom? Briefly explain.8) 8) In the next section I want you to find Salt Lake City in GoogleEarth. Once thereensure that you are viewing the aerial photographs. Use the scale tool to zoom in andout. While doing this note the reservoirs of water found in the local area (i.e. riversand lakes). If you do not have GoogleEarth on your computer you can use earth view ingoogle maps.https://maps.google.com/maps?ftr=earth.promo&hl=enList the seven creeks that enter salt lake city?9) In this next activity we are going to determine where your drinking water comesfrom. Open the following link. Under the “Water Program Snapshots” tab on the rightside of the screen click drinking water information. Then look at the surface waterreservoirs. Type in your address in the upper left corner.http://watersgeo.epa.gov/mwm/ Find the water shed that is closes to your home and click on it. What is the name ofthis water shed? How many people does this source serve?What do you think our responsibility is in protecting our local water sources?
  5. 5. 10) Finally, explore the following webpage concerning different issues surroundingaccess to water.http://www.nrdc.org/water/What is something an individual can do to protect our water sources?What can be done on a societal level to better protect our water sources?
