From the creators of the What If ...? Conference comes a quirky book that encourages kids to explore and engage with the world around them by asking more than eighty wild, absurd, and thought provoking questions. What if a book didn't just tell you how to think or what to know, but rather encouraged you to think for yourself? What if there was a book that focused on asking questions instead of just answering them. The Book of What If ...? does just that! What if you lived on a floating city? What if politicians were kids? What if broccoli tasted like chocolate? What if you could explore outer space? By asking these fun, open-ended questions, this book fosters greater critical thinking skills and gives kids a space to interact by breaking out a notebook to draw or write out their personal reactions, or engage in entertaining exercises with family and friends. Plus, sidebars deepen the investigation with peer-to-peer insights, historical and current profiles, real-life examples, and more, making for unlimited learning opportunities! Divided into sections--history, people, stuff, and nature--along with four introductory text to open up a dialogue about why it's important to be inquisitive and to always ask questions.
