TIME for Kids The BIG Book of Why: Awesome Animal Kingdom answers the why, what, when, where, who and how questions about humans and animals that kids commonly ask, but adults can rarely answer. Why do we have eyebrows? What’s the difference between a crocodile and an alligator? How does aspirin know where to go in the body to take care of pain? What’s the fastest a human is capable of running? Why do animals’ eyes glow in the dark?

Written in an upbeat manner, each answer is accompanied by either a photo or an illustration to show the reasons why. Of course, TIME For Kids goes beyond answering the question, and dips into the science or history to further explain the answer in an easy-to-follow, straightforward manner.
