When I was growing up, we had discovery channel. That sparked my intrinsic curiousity. My daughter has that intrinsic motivation as well, but only for k-pop now. She likes youtube videos and she likes when I tell her about science stuff. Maybe I can combine that by recommending her some good youtube channels.
Dr Becky (aka Dr Rebecca Smethurst) for Astrophysics / Space news.
Any of the channels run by Brady Haran like Numberphile and Periodic Videos.
Most of my other picks have been mentioned already or else lean into spectacle which might not be appreciated by a 12-year-old girl. (Quite a few of the chemistry channels I watch are like this. In order of decreasing silliness: Nile Blue / Nile Red, Labcoatz, Amateur Chemistry, Chemical Force… Actually CF is pretty good by comparison.)
But I’m not you or your daughter. Check them out anyway and see if either of you likes what you see.
