Thing #21 Diving into Podcasts

I love the Podcast.com directory! Without even searching, I found 4 sites on the "Top 25" that would be helpful to me as a science teacher. NOVA, Discovery News, BBC and "Stuff you Should Know"... yea! One of my daughter's math teachers started off many classes with a brief clip from YouTube. It was an entertaining way to get the kids engaged right off the bat, and motivated them to get to class on time, so that they wouldn't miss the show. Why not use the same technique, but with an educational video or audio podcast about a current event, or pertaining to the topic of the day?
