Educational tv/movie suggestions that are not cartoons

I'm looking for tv shows that are educational but do not involve cartoons, for school hours. The plan is to compromise with my kids and give them tv access after their responsibilities are taken care of but still encourage them to lean into play over tv during the school hours. I notice even educational tv shows suck children in and only provide minimal education and a lot of dopamine. I'm needing low dopamine informational videos like documentaries. My kids are still young so tv shows that do not talk about war/sex/drugs are preferred. TIA!

Edited: thank you for the recommendations!! We will be using a lot of these!
