Scrapblog is another in a series of very neat Web 2.0 tools that I could see a teacher using with a class. Students would need their own account, but it allows them to create some stunning visual representations of what they are working on. It's like a slideshow, with extras. Imagine multiple digital scrapbook pages that you can email or embed. You can try it out by clicking on the "Get Started" button, but to save, print or export, you need to be logged in. (You can always take a screen shot of your creation using "shift-apple-4" on a Mac, and then use the pic in other applications.) Let me know if you try it with a class.
