How This Web Site is Organized

The Science Odyssey Web site is divided into three distinct levels:


Home Page

The home page contains an image map with 12 selections. Text equivalents for these graphic links can be found directly below the image map.


Level 1 Pages

There are eight Level 1 pages: "Then and Now," "That's My Theory," "On the Edge," "You Try It," "People and Discoveries," "About the Television Series," "Resources for Educators" and "What's Happening in Your Area." Each Level 1 page contains a list of options. Choosing one of these options will lead you to a Level 2 page. General site navigational links may be found at the bottom of each page.


Level 2 Pages

Level 2 pages contain activities, games or information relating to a particular category. Where necessary, some Level 2 pages contain text-only versions to make navigation easier when using a screen reader. General site navigational links may be found at the bottom of each page.
