Also, a good topic will be one that has a human element: humanity in conflict with society, science, itself. Do not begin work until you have verified your topic with your teacher. This part of your web may include several pages linked to the opening page.
The purpose of any paper is to explore and learn about a subject and to extend our thinking. You could include a collage, a poster, a book, a CD cover. But beware -- this should not be a haphazard collage of disjointed stuff; you must connect the genres and what they represent with a central, significant theme (a thesis). As you research, you'll need to consider an audience or audiences who would be interested in your topic, and you need to consider what genre/s would be effective for communicating with those audiences.
If you provide your reader with reoccurring images or phrases, or a running commentary or even a narrative or story, you will create unity that will help your reader better understand your central theme.
This can be much like making sure to weave your thesis throughout a traditional essay paper.
In addition, when we publish our writing on the web, we are sharing our ideas, our feelings, our thinking with others, which creates a web of human understanding. You'll need to be fully engaged in your research -- don't approach it as if you were on a scavenger hunt to find information to spit back in an "academic" paper, because you're not. You'll need to introduce the subject and anything you think the reader should know about you and/or your project before they read it.
So are plays and diaries and cartoons and billboards. It's a collection of pieces written in a variety of genres, informed by your research on a particular subject, that presents one or (more likely) more perspectives on a research question or topic. You could write an editorial, a poem, a dialogue between characters, a letter, a debate.
