1. Open your Internet browser. (i.e.; Netscape, Internet Explorer, etc.)

   Be sure your browser is showing the url address you are visiting (called the "address bar" in some versions of Internet Explorer, or "location toolbar" in some versions of Netscape).

   Also make sure your browser is showing the basic navigation buttons (called the "standard buttons" in some versions of Internet Explorer, or "navigation toolbar" in some versions of Netscape).

   If either of these toolbars do not show up on your computer, ask your neighbor or lab assistant if you need help.

2. Type in the address: http://wow.nrri.umn.edu . (Type the address in carefully. Some people type in the first three letters incorrectly out of habit. It is "wow".) This url address will take you to the home page for Water on the Web (WOW).

   The major heading on the WOW home page are:

   Overview, Understanding, Data, Teacher, and Student. Notice what happens when you simply move the cursor over those terms. (Don’t click the mouse yet.)

3. Now move the cursor over the phrases "What’s new" and "Search" on the left hand side of the home page. Notice the cursor changes form when you move over these phrases. Click on "What’s new". It’s useful to check this link every couple of weeks. This is where you will be alerted to changes in the website.

4. Now click on the "Back" button (on the top left part of your browser toolbar) to return to the home page.

   Here’s a summary of the purposes of the buttons on the home page:

   Overview — provides an introduction to WOW, the technology involved, and the people who are making it happen.

   Understanding — provides extensive resource information. It includes: a primer that summarizes key concepts of lake ecology, GIS information related to the lakes studied, background information about the lakes, details on the RUSS (Remote Underwater Sampling Station) and the water quality parameters it measures, and a glossary of lake ecology terms.

   Data — provides water quality data for the lakes studied in both numerical and graphical forms. It also provides environmental data related to the WOW lakes.

   Teacher — provides teacher lesson plans that guide teachers in using the resources and student lessons available through WOW.

   Student — provides student lesson plans in two formats: concise, directed study lessons and extended, inquiry investigations.

   What’s New — provides updates on WOW technologies, people, data and changes to the website.

   Search — allows you to search the web site for specific topics.

   Site Map — provides a graphical image of how the website is organized and where you are in that structure.

   NSF — identifies one of the major sponsors for this project and links you to their website.
