This Cold War webquest is quite comprehensive. It walks students through the four decasdes of the Cold War and covers not only the history of the Cold War and the historical events of the timeperiod, but also how these events impacted the culture. The unit was designed to last a full grading period and to be supplemented with mini lectures by the instructor.
The webquest includes individual and group work, covers all levels of Bloom's taxonomy and many of Gardner's multiple intelligences. It links to many YouTube videos, and if these are blocked, it would be recommended that you create a free wiki at www.pbwiki.com and use the YouTube embed codes to add the videos to the wiki. Links can easily be changed in the PowerPoint so students can then access te videos via the wiki so they are not exposed to the additional content on YouTube.
