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.

The power of glaciers is explored. Go inside a glacier to see its spectacular beauty and raw power.  Video takes place in Norway.  Scientists are starting to understand the power of ice.   Scientist use hot water, spraying for two days, to get inside and see the inside.  They go inside and see the ice, there is about 200 meters of ice around them, and if they would stay there for approximately 48 hours the ice would close in on them.  The glacier is not really a solid mass of ice, it has water pockets.  In three days the ice cave disappears.   Video is very interesting and is very good quality.   Good for elementary grade and middle school students.

  • 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.
