The Mystery of Matter: Search for the Elements video series
If your not familiar with the video series "The Mystery of Matter, Search for the Elements" then I highly recommend their use as part of your curriculum. The Mystery of Matter: Search for the Elements is a PBS series about the amazing human story behind the Periodic Table. The videos, most of them 4-12 minutes long, draw on the interviews, re-enactments, animations and photographs that were shot and collected for the PBS series, with supplementary animations and images as needed. In all, the videos make up about three hours of programming. I shared several of the video clips with my high school students and they really seemed to enjoy them mentioning the reason was because the videos were done using actors to tell the stories and it was similar to watching a movie.
