Adding on to my original answer, there are a bunch of shows on PBS Kids that will meet your criteria. Here are a few off the top of my head:
Cat in the Hat Knows a Lot About That. Covers nature and science topics. More about learning and interacting than experimenting. Also available on Tubi.
Work it Out Wombats. This one didn’t appeal to my kids so I’ve seen just a couple of episodes, but it’s about solving problems in a systematic manner.
Mega Wow. Live action. Only like 10 episodes but my kids are crazy about it right now. Hands on exploring of scientific topics.
Elenor Wonders Why on PBS Kids. Each episode is ~ 20 minutes, broken into two ~ 10 minute stories. Cute animal kids explore nature and/or experiment in an inquiry-based manner. Many episodes have a song covering a history of science topic at the end of a segment. Animated with a calm, quiet aesthetic.
I come with my wife in a big bed.
Hahahaha! This contest is over! Give that man the First Annual Montgomery Burns… uh… Award for Outstanding Achievement in the Field of… uh… Excellence.
