I have a younger sibling who watches YouTube all day, and I have just installed (among other things, including Fedora KDE!) FreeTube on their laptop, and it has a convenient profiles feature to separate, for instance, educational and not so educational content.
What are some good sciencey channels that are easy to follow and are run be nice people (rather than bots or similar)? I’ve got SciShow, Clint’s Reptiles, and a few others already, but what are some good ones that you all know? They are currently interested in animals, particularly sea creatures and reptiles, but other topics are fun too (history, chemistry, CS, whatever are all good!)
No specific recommendations, but make sure it’s something they enjoy. Bad content will turn them off from science as a whole. If they lose interest in a creator, don’t press them. Just find something else and move on.
