I’m a former HS science teacher myself and I’m going off my sons 6th and 7th grade science texts and how they cover the basics. Biology, geology, ecology, physics, and chemistry. Explanations, diagrams, and summary questions all seem to be well written and cover the topics well. Currently my son is studying cells and cell theory and I challenge you to look at his textbook and any “normal” textbook and tell me his doesnt cover the topic just as well.
BTW, they also get their hands dirty with labs and projects. To me, science cannot be studied any other way.
And why not mention God? We all know religion has played a part in science both good and bad. Also why not examine the possibility of some devine intervention in nature?
