"Shift Happens",  by Karl Fisch and Scott McLeod, is an interesting take on paradigm shifts, globalization and change.  You can view this video at http://www.glumbert.com/media/shift . 

 

The website http://shifthappens.wikispaces.com/, provides additional insite to the video and suggestions for using it in the classroom.

 

Obviously, there are ideas in the video/presentation that can be challenged, but that is the fun part of showing it.  You will effectively encourage students to think!
