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
( we search for these through netflix, because they're better than the PBS site)
(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)
(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.
