I would love some guidance on how to take advantage of OCW w/ my kids. I don't want to reproduce Ahaan's story. My father was a biology teacher and always had tons of text books we could just kind of grind through growing up. I'm not doing the same for my kids at this time- mostly for lack of resources. Just skimming through the OCM content- I don't see material in physics or science that can be used to introduce kids to the scientific method. It mostly looks like baptism by fire. Any tips?
