The Curious Kid's Big Book of Why answers 300 questions across ten journeys: space, animals, the human body, everyday science, the oceans, dinosaurs, weather and the restless Earth, food and cooking, the mind and the senses, and machines. Every question has its own drawing.
Each answer is about a hundred words: long enough to explain properly, short enough to read aloud in under a minute. Open it anywhere. No order, no homework, no tests.
What makes this one different is that the answers are checked. Each one was written against published sources from museums, universities, national science agencies and peer-reviewed journals, then checked a second time against those same sources. Where scientists genuinely do not agree yet, the book says so.
