This book is an excellent textbook for teaching anatomy with a Biblical perspective! I am a physical therapist, so I had four semesters of anatomy and physiology in college. While I have always marveled at how God created us, this book has brought even more interesting correlations to me. it has enough depth for fifth and sixth graders, yet it is concise enough to keep my six year old interested. We love the various "Try This" experiments in each chapter.
First the slight downside. I lowered the score on meets expectations because I do not want to have to plan out things like tests and quizzes. I want my children to see how well they are doing and what they can remember by having such things, but that is not to be found in this curriculum anywhere. Now that is probably about the worst I can say about this.
My children loved reading through this book. We were reading through it together, but for some reason that wasn't working. So anyway, I had them read a designated amount on their own and they loved that! They were so excited to share what they had learned. I was using this with a 4th, 5th and 7th grader. We did also use the journals, which I feel was a worthwhile addition.
Simply the cost of the book and the content of the subjects, this is a good read. Lots of details included throughout, not just an exposure to a topic but an in-depth look at the various systems of the body.
