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.
I really like physicist Dr. Angela Collier. Not all of her videos are about science, but at least the plurality are. Her videos are generally pretty casual, and she doesn’t really script.
I also really like Practical Engineering for civil engineering stuff.
I wonder if Collier might not be a bit too advanced for a 12-year-old who, it sounds like, is just starting to develop an interest in science. Might need some curating, maybe?
