Not Right For WatchKnowLearn
WatchKnowLearn ratings are intentionally harsher than what you might find on YouTube, for example. Most of our videos have been imported by people who want to use them with kids, not by the creators of the videos. We take a hard-nosed attitude toward quality. Four and five stars should be reserved for really excellent quality. Three stars isn't bad. Two is often watchable and shouldn't be ruled out.

  • 5 stars = Exemplary.
    Unusually helpful and well produced. Do not overuse this, please; it is not the standard rating for decent work, as it is elsewhere.
  • 4 stars = Very Good.
    Very helpful but not among the very best; adequately produced, at least.
  • 3 stars = Usable.
    Reasonably helpful, perhaps a bit amateurish in production or has some other problem; there is nothing wrong with a 3-star rating for amateur work!
  • 2 stars = Some Merit.
    Minimally helpful; not completely worthless or inappropriate; you can see how it might be useful to some people.
  • 1 star = Not Right for WatchKnowLearn.
    Not at all helpful, not educational, poorest quality, etc.; you can't see it being useful to anyone.

From worldsciencefestival.com (Approved: Rockefellerteacher), produced by World Science Festival 2011
 
Despite being one of the oldest senses, our sense of smell is easily one of the least understood. It’s also the only one with a direct
connection to our brain. With each breath we create a detailed picture
of our environment. It can warn us of danger, or lead us to food. Some
smells may even trigger behaviors without our knowing it. In Scents and Sensibilities, we’ll explore how our sense of smell works, how other
organisms utilize it, and how it has such a hold on our emotions and
memories.  (02:05)

  • Unless changed, the Finder is the person who uploaded the video to WatchKnowLearn.
  • The Finder is allowed to "lock" information about the Owner and Producer (so other accounts cannot edit this information). The Finder field should match the Owner field when a video is entered in a contest.
  • As owner of a video, you can have finder rights transferred to you.
Simply click "Request Finder Rights" and an e-mail will be sent to the current Finder of the video. The Finder may then transfer rights to you. If he or she does not, bear in mind that an Administrator will see the refusal of your request and will be able to review it.
