Fridays In The Lab: Oct. 6th Pre-Visit Activity
Developed by Kaitlin Friedman

Exercise #1.
  1. Open a web browser and go to http://www.topozone.com/.
  2. In the lower left corner, you'll see "Place Name Search." In this box, type "Bryn Mawr College" and select "PA" for state, then click "Search."
  3. When the next page appears, you'll see a prompt at the top of the page telling you to click on the Place name link. Click on "Bryn Mawr College."
  4. On the next page, you'll see an image of a map that is "zoomed in" on Bryn Mawr College. On the lefthand side, change the map size from "small" to "large" so you can see more of the area surrounding Bryn Mawr.
  5. Locate Mill Creek.
  6. Using the scale selection drop box ("View scale") and the arrows that point left, right, up, and down, trace the path of Mill Creek to the ocean.
    Consider these questions:
  1. How far do you think an organism we find at Bryn Mawr College would go along this path?
  2. What other bodies of water might it encounter along the way?
  3. Would it pass landmarks that you recognize?
  4. Where do you think it would end up?


Exercise #2:
  1. After you have completed this activity, go to http://www.google.com/maps.
  2. On top of the map of the United States, click "Satellite."
  3. Again, search for Bryn Mawr College and click on the first entry.
  4. See if you can repeat the activity above using the satelite images.
           
        Email Questions (Comment on only one):
  1. What differences do you find between using the satelite images and using the topographic maps?

       OR

  2. How do humans impact/interact with watersheds?
