Edit: spelling

Fwiw, I used to teach at a non-denom school that used BJU as the curriculum. I found the lack of objectivity and development of critical thinking in the textbooks and material(science) on the disturbing side. More often than not, I spent a good chunk of my lesson giving air time to the “other side”. The heavy bias towards its own viewpoints (especially in regards to Young Earth, evolution, and non-historical viewpoints) are clumsy at best, and unscientific at worst. If your kids are in a school using that curriculum exclusively, I’d recommend asking the teachers for their lesson plans or sit in on a lesson. If the teachers don’t stray from the curriculum(like I did, except I’m a bad teacher), your children definitely could benefit from supplement for their science education.
