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. Margaret and Elizabeth like to visit the Science Museum of Minnesota. The museum has a mini-golf course that was designed so kids can learn about rivers while putting. As they played, the girls began to wonder how real rivers work and what rivers do to the land. So after their game of golf, they packed up their canoe and headed for a local river. the canoe ride showed the girls how rivers meander; or twist and turn, and how the water deposits rocks and pebbles on the inside of each curve. They also learned how sediment layers develop in water; and how humans change river flow with dams.
