I've heard a few mentions of projects involving students creating timelines- I mentioned in my group a blog post that summarized a few tools that allow you or better your students to create media rich timelines that are on the web:
I think one of the best tools out there is TimelineJS
TimelineJS is an open-source tool that enables anyone to build visually,rich, interactive timelines. Beginners can create a timeline using nothing more than a Google spreadsheet. Experts can use their JSON skills to create custom installations, while keeping TimelineJS's core look and functionality.
It can pull in media from a variety of sources and has built-in support for Twitter, Flickr, Google Maps, YouTube, Vimeo, Vine, Dailymotion, Wikipedia, SoundCloud and more.
If you run your own Wordpress blog (not hosted on Wordpress.com) there is a plugin that incorporates TimelineJS
