What am I supposed to do?

The Particle Adventure is divided up into "paths" of information. We suggest that when you return to the home page you click on one of the three paths and explore it fully, taking occasional "side trips" to explore interesting concepts. The paths are:

• The Standard Model of Particles Path: An interactive lesson which introduces you to the known particles, and how they interact.

• The Experimental Evidence Path: This path shows how physicists have obtained the data which supports the standard model.

• And, finally, the Beyond the Standard Model Path explains how much has yet to be discovered.

The Particle Adventure is very large. To prevent you from getting lost, at the top of every page there is a topic heading, navigation buttons, and a link back to the home page. If you truly are lost, and want to get back to a section you left a while ago, click on the "I'm Lost" button that is at the top of every page. Should you come across an unfamiliar term, go to the Glossary of physics terms available through the Complete Menu of Topics.

To stay on a path, click on the back and next buttons.

Test yourself by clicking on the beautiful buttons.

At any time, you can get back to the home page by clicking on the green "Home Page" button. Click on the button now to return to the Particle Adventure Home Page.

• I do not understand the difference between the "Back" and "Next" buttons and the browser's "Back" and "Forward" buttons.
  The "Previous" and "Next" buttons are designed to keep you on one of the several "paths." You may have landed on a page via the home page and wish to see what pages precede or follow it on the "path."
