So this book has great modern graphics with categories such as Senses, Reproduction, Brain etc. An adult can learn from this yet spot on for ages 6-9 as recommended. If you want to explain conception, childbirth, stool, the Coccyx (remnants of tail bone), how a fart is created, 80% of people dream in color, how quick thinking happens and how many times a heart beats in a seventy-year lifetime then you will enjoy this book!This was a useful tool for my classroom and my students enjoyed the engaging way of presenting information.Colorful and fun to look at.bought for our road trip hope it keeps them busy.Checked this book out from a local library a few months ago for my 4 year old who's interested in skeletons/human body. She loved it! It was easy enough for her to understand, and the illustrated tabs made it simple for her to find and navigate to different subjects of interest. She said she wanted a book about skeletons for Christmas, so I just ordered this book for her :)This book uses a novel way to learn more about the human body and how it works. Bright colors, cool graphics and simple figures are used to convey all sorts of information about everything from the senses, the brain, the heart and the human skeleton to digestion, reproduction and the types of substances the body produces (mucus, hair, poop, etc.).The author's tone is light and playful but the information here is all right on the mark. Humor and interesting trivia are also used to make this a more entertaining read and even adults will probably learn something they didn't know.Book provided by publisher.This is an excellent, informative book that my 10 year old daughter has enjoyed reading and learning new facts from. The layout is simple and easy to follow and the information and facts are clear and concise. I recommend this book to any young aspiring Scientist and any parent who wants to help their child with their Science homework about the Human Body. The book is divided into tabbed sections so you can browse through it in any order to find what you are looking for or you can just read it from start to finish. The illustrations are fun and quirky. My daughter loves this book and I know she will continue to use it for a long time to come.
