    You can adjust the size of most of the text on our site using your web browser.

    • Microsoft Internet Explorer
      Go to the View menu and choose Text Size.
    • Mozilla and Netscape Navigator
      Go to the View menu and choose Text Zoom.

  • Printing

    You should set your printer for "Landscape" mode. This setting varies from printer to printer. In Microsoft Windows it is usually located by clicking the "Preferences" button on the print panel.


  • Plug Ins

    Some of the content on our site requires "plug in" software to view the material. You'll need Adobe Acrobat Reader to view "PDF" files. You'll also need the latest Macromedia Flash Player to view the interactive and animated activities. (You probably already have the Flash player, but it may not be the latest version.)
