"She asked 'why' about everything now she actually knows!"
She asked 'why' about everything now she actually knows!" We got this for our 8-year-old and she carries it everywhere. The questions are so cleverly designed that she started connecting things she learned in school to real life. Absolute winner.

"Best science book for kids I've ever bought"
Best science book for kids I've ever seen" Bought this as a Christmas gift for my nephew and his parents called me a week later saying he won't put it down. The illustrations are incredible and the questions actually make him think. Way better than screen time.

"Funny, engaging, and actually educational"
Funny, engaging, and actually educational" I expected a typical kids' science book. What I got was something my daughter and I now read together every night. The way it breaks down big concepts into simple "whys" is genuinely brilliant. We're already buying a second copy for her classroom.
