Scavenger Hunt Through History!
From the Freedom: A History of US. | PBS site. A great little game where you put events in their place on a timeline!

As so often, sound would help so much. You should get to hear at least a little of the material presented when you get a right answer. Also, wrong answers get no feedback at all. And, at this time, some of the segments don't work entirely correctly.

Still, I love the educational approach of this game. Being able to place things in order, and in general time periods, is critical to deeper thinking about the events.
