It seems this thread didn't get much traction, but I'd love to get good recommendations for tv shows or documentaries that are educational but also fun for kids around ages 6-8. There are times when we don't mind allowing a bit of screen time but would prefer that it be educational.

Over the years, DS7 and DS5 have loved Dinosaur Train (which teaches a surprising amount about geological periods, climate, etc.), Magic School Bus and Wild Kratts. They've pretty much outgrown those, but are not yet ready for documentaries that are aimed at an adult audience. Is there anything in between?

We found a few great SciQ DVDs at the library but couldn't find more. We tried Bill Nye, but I think they found it too cheesy.
