As a homeschool mother, this book has been an excellent tool in introducing my 6 year old and 3 year old to the animal kingdom. As my 6 yr old has said, "it has everything." As an adult I may have choosen to include more, but for my daughter, it is like front row seats to the zoo. It has large pictures, simple descriptions, and kindergarten age experiments as well. We have already made a bug habitat, a frog habitat, crafted a paper fish with scales, and made a mobile food chain, and that was in the first two weeks. I find myself wanting to teach science all the time. It really is a great book to enjoy with my daughters.
