Hi Carrie,
Here are the rules for the Autodesk Visualization Design Competition:

You'll need to upload your animation to Autodesk's web site, but post the storyboard on your own.
A Storyboard is just a series of simple sketches showing all the scenes & events of your video. Most of us will sketch out a storyboard on paper, then scan it into the computer. You should create the storyboard first, then use it as a guide to make your animation. That's what "real" TV & film directors do.
Here are a few storyboard examples I found on the Net:
