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 pbskids.org (Approved: begamatt), produced by PBS Kids
 
From DragonflyTV. Tyler and Aditya are roller coaster maniacs! The boys head to the Carnegie Science Center in Pittsburgh, to ride a roller coaster simulator. They took a measuring device called an accelerometer to find out which part of the simulation produced the most g-forces. Unfortunately, the simulator didn't produce the actual g's of a roller coaster. So they then took the accelerometers to a real roller coaster at a local amusement park and measured the number of g's on the accelerometer at different places along the ride. During the investigation, the boys learned that acceleration is speeding up, slowing down, or changing direction. They experienced the greatest g's at the bottom of the steep hill, when the direction changed quickly... almost 5 g's! The video/investigation is a great example of problem solving and the scientific method.

  • 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.
