The colorful format attracts attention and the short presentations are appropriate for younger viewers (elementary, middle, and even high school students). The site relies primarily on Flash to present the stories, but viewers can also read and view the stories in HTML.

Each segment provides links to outside resources (about 40 in all) for additional information.
