ChronoZoom by Microsoft
Finally, an online timeline resource that is worth posting about. ChronoZoom is free, easy-to-use, and open source. While it looks a lot like Windows 8 (and a lot like Prezi) it is really much easier to use. After creating an account or just logging in with your Google account, you can start creating or adding to timelines that already exist. Below is a screenshot of a timeline in progress on the Earth and Solar System.
Additionally, the help guides that come with the site are actually…helpful. Thank you, Microsoft. And because the project is open-source, users have the options of adding their own timelines or modifying existing ones. If you are super hardcore, you can get into development.
This is a great resource for class projects in all subjects – small group or individual. Start creating today!
