The creators of the “Did You Know” videos put out new videos every couple of years. I think they are very interesting and when my students have watched them they really enjoyed them. If nothing else, they really show how much technology is infiltrating our world and how important it is to keep our students (and ourselves) on top of technology.
Not to mention, I find it super interesting to see how much we have advanced and how quickly. Sites like http://gcn.com/articles/2007/12/06/25-years–a-technology-timeline.aspx and http://inventors.about.com/od/timelines/a/twentieth.htm give a pretty good list of advancements, but the videos are more appealing to students. This might not be a bad idea to incorporate into an internet scavenger hunt for students or teachers to appreciate the need for forward movement.
