blubbr is a site I learned about earlier in the year from Danny Nicholson's blog The Whiteboard Blog.  At blubbr, you can play quizzes or create your own where a YouTube clip is played, and then a question is asked.    These quizzes are called trivs, and many of them are broken into categories, including Education.  Creating my own triv was quite simple.  Try your hand at the triv I created about the 1960's.
