Book excerpt:

Why do we have eyebrows? What's a black hole and what happens if you fall into one? What's the fastest a human is capable of running? Why do wet fingers stick to metal in the freezer? Where is the deepest point on Earth?

Divided by subject area - humans, animals, environment/nature, technology, and space - and 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 by dipping into the science or history to further explain the answer in an easy-to-follow, straightforward manner. This is a must -have book to satisfy the most curious of kids and provokes a great way to encourage interest and knowledge about a wide range of subjects, as well as to stimulate reading. Kids will be desperate to share what they've learned with their parents, teachers, and friends...and anyone else who will listen.
