I'm not a parent, but I remember as a kid in the 80s watching PBS specials during the day on science that were packed with interesting content. I stayed out of my parents hair during the summer watching these things. Yes, admittedly I was probably not the typical child. But are there not public service lecture series on Youtube by teachers (funded by foundations, etc) that have produced videos for all kinds of grade levels and subjects?

Why do parents have to make up curricula to teach?
