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 Dragonfly TV. Vanessa and Chris are crazy about astronomy! They've even made our own telescopes. While looking at the moon one night they noticed just how many craters there are on the moon and could even see differences in the various craters.  The question that have to investigate: How do craters form? They began their investigation by putting a deep layer of flour into a cake pan and sprinkling a thin layer of cocoa over that. They found some marbles to act as meteors and got ready to drop the marbles into the cake pan from four different heights: 50 cm, 100 cm, 150 cm and 200 cm. They measured the diameter of each crater and compared their homemade craters to the ones they could see on the moon, using the telescope at the Yale Observatory.

  • 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.
