What I would wish to instill in a growing mind is that life is not static. Nature is dynamic and always shifting, and the living world is part of that. Evolution is not separate from biology. Evolution is just biology over time.
I have serious reservations about scientific claims made by BioLogos that appear, at least to me, to be false. Hopefully these issues have not extended to their homeschool curriculum.
Last night I emailed @Kathryn_Applegate, asking for a copy of their curriculum so I can assess it for myself and decide if I can recommend it or not. She hasn’t answered me yet, but I expect she will soon.
Most of those arguments are at a much higher level than middle school biology curricula. If nothing else, those disagreements can serve as examples of what healthy scientific discourse looks like. One important lesson that all students should learn is science is open to change, arguments, challenges, and debate. Christian scientists can disagree about science and theology, but still agree on the basics of Christian belief.
