I highly recommend this book for those interested in marine life and parents who want an easy to understand textbook. The only special items to buy are for later chapters(dissection purposes) but lab materials are mostly household items.
I just received my son's books last week and I love the pictures and experiments. We've already done Apologia Creation Science and Biology. We like how simple, yet detailed, the books are. I know my son will be ready for college (or anything!) by studying these books. He really enjoys Apologia! Thank you so much!
