The students can watch the video (several times, or in the computer lab) and they answer 14 questions about the history of Wikipedia. You can use this as an introduction to a class devoted to Wikipedia.
With my classes, we compare the English and French versions, looking up various topics, and we also work on an article entitled "Wikipedia, Trust but verify", published on MSNBC.com that explains that many colleges in the US banned its use as a primary source of information.
We then have a debate on how they use Wikipedia, what for etc. The students are usually pretty interested.
