I haven’t done any strict fact checking but as far as I know science.tv‘s new blog, called simply Science.tv Blog is the first web log launched by a science video sharing site in order to communicate and explore. (Usually I am accustomed to the other way in the world of online video: blog first, vlog or tv second, think about BoingBoing or Make.)
Matt Thurling, science.tv founder has some valuable considerations on how to catch (video) school kids conducting genuine experiments attempting to answer their very own hypotheses be it on Nintendo or ants.
PS: In my opinion a WordPress or Movable Type blog would be a better choice for science.tv than Blogger.
Deep, healthy lifespan extension 
I’ve had to move the location of the blog to http://www.science.tv/blog/blog.html
What are the main advantages of WordPress or Movable type over Blogger?
