Oh yikes...there are TONS.
- Magic School Bus
- Walking With _______ (series, BBC, some titles include: Dinosaurs, Prehistoric Beasts, Allosaurus, Monsters -before the dinosaurs-) - Stunning visuals, and streamable on netflix.
- The Universe (History channel) -stunning visuals
And a HUGE number of titles from each of the following:
- National Geographic Society ... their regular documentaries, although the kids ones are okay, all of the regular ones are the ones the kids I know fall head over heals for. http://shop.nationalgeographic.com/gateway/128/105.html ... or www.netflix.com
- Nova
http://www.pbs.org/wgbh/nova/
- PBS
( we search for these through netflix, because they're better than the PBS site)
- BBC
(the BBC site is great, but you can't stream OR ship to the us, and the usBBC site is not great that great, so again, netflix)
- Imax
(My 7 year old actually hates these...they're MUCH slower paced than any other documentary, and they -quite frankly- don't have as many great special effects as the bbc/pbs/nova specials do).
- Discovery, or Discovery Kids

Gee...I feel like I'm forgetting something. If I remember I'll update. For pure fiction though...check out Avatar, the Last Airbender.
