There are today so many good programs that divulge science, one avenue in particular is The Science Channel. The question is how can we best use this documentaries to motivate science students? Through the Wormhole is a series that is worth watching. http://science.discovery.com/tv/through-the-wormhole/
They are bringing to public notice, ideas and research that is way out at the frontier of discovery. One idea is to ask students to watch a particular program and then have a class discussion about it and if there are misconceptions either explicit or implicit then these can be addressed by the professor in class and of course can be used to show the students that science is always evolving and new ideas are constantly being advanced. Not always within the consensus of the established scientific community.
