+ Meograph (http://www.meograph.com/)
Meograph offers a nice way to create narrated map-based and timeline-based stories. Much of what Meograph offers can be accomplished in Google Earth. However, Meograph is browser-based so that students can create stories even if they cannot install Google Earth on their computers.
+ Dipity (http://www.dipity.com/)
Dipity is a great timeline creation tool that allows users to incorporate text, images, and videos into each entry on their timeline. Like most good web tools, Dipity has a collaboration option and has multiple options for sharing your timelines publicly or privately. Each entry to a Dipity timeline can include multiple types of media which allows users to add more detail and information than can be included in a traditional timeline. If you want to import Tweets and other social media messages, you can do that too on Dipity.
+ myHistro (http://www.myhistro.com/)
myHistro is a timeline builder and map creation tool rolled into one nice package. On myHistro you can build a personal timeline or build a timeline about a theme or event in history. Each event that you place on your timeline can be geolocated using Google Maps.
+ XTimeline (http://xtimeline.com/)
I like XTimeline because I find it to be a great service that is very accessible to high school students. Using XTimeline students can collaborate, just as they would when making a wiki, to build a multimedia timeline. Timelines built using XTimeline can include text, images, and videom
+ TimeGlider (http://timeglider.com/)
TimeGlider offers some nicer layout features compared to XTimeline, but is not quite as intuitive to use as XTimeline. The layout features that I like about TimeGlider is the ability to stagger or indent events below each other in a sequence.
+ Time Toast (http://www.timetoast.com/)
Time Toast is easy to learn to use. To add events to a timeline simply click on the inconspicuous "add an event" button and a simple event box pops up in which you can enter enter text, place a link, or add a picture. Time Toast does not have the more advanced editing options that XTimeline and TimeGlider offer.
