We are currently in Biology from this same publishers. It's easy to understand and best of all it refers to God and the Bible being the only infallible Truth.
It has given me faith and intensive to keep homeschooling my children through high school now that I have good tools to teach science.
Plus, when he's done, we will go to a college for a test in Biology and possibly earn 4 college credits. It has helped that we are doing the lab with two other home school families and keeping to a schedule. It makes lots of work more fun doing it with others.
Thank you for your integrity and His Truth in your curriculum.
We will start the Chemistry after he finishes the Biology.
