Your child asks a hundred questions a day. This answers them.
Why do we get goosebumps? What did the Egyptians do with a pharaoh's brain? Why does bread rise? Every page of 100,000 Whys takes one question a curious kid actually asks and answers it in a minute. in plain language, with full-colour illustrations on every spread.
No homework feel. No lecture. They open it anywhere, learn something strange and true, and come find you to explain it.
That's the part (grand)parents write to us about. Not the facts the fact that their kid put the tablet down without being asked, then spent the car ride to school explaining mummies.
Curiosity is a habit, and habits are built early.
Perfect for ages 5–12 · Full-colour paperback · Reads aloud beautifully at 6, reads alone by 9

Loved by Curious Kids. Trusted by Parents.
See why parents, grandparents, and teachers say this is the book that gets kids asking questions, discovering new things, and actually excited to learn.
My 8-year-old has started carrying this book around the house and reading random facts out loud to whoever will listen. Yesterday at breakfast he spent ten minutes explaining something to me that I genuinely didn’t know. He was so proud of himself. I love seeing him this excited about learning without it feeling like schoolwork.
My son is usually much more interested in his iPad than books, so I honestly didn’t expect much. I left this on the coffee table and a few days later found him reading it by himself. Now he’ll randomly come over and tell me some crazy fact he learned. Anything that gets him choosing a book over a screen is a win for me.
I originally bought one for my oldest, but all three kids ended up fighting over it. What I really like is that they don’t have to read it from beginning to end. They just open to whatever looks interesting and start reading. It’s become one of those books that’s always lying somewhere around the house.
I bought this for my grandson’s birthday because I wanted to give him something besides another toy. He started looking through it while everyone was still opening presents! His mom later told me he keeps it next to his bed and reads a few pages at night. I think I know what I’m getting the other grandchildren now.
I keep a copy in my classroom and my students absolutely love it. Even some of the kids who normally avoid reading will pick it up during free time because they can jump straight to a question that interests them. It gets them asking questions, discussing the answers, and wanting to know more which is exactly what I want as a teacher.
My son is constantly asking questions I don’t know the answer to. Why do we dream? How big is space? Why do we have fingerprints? Now half the time I just tell him, ‘Go see if it’s in your book.’ He loves looking things up himself, and usually comes back to tell me three other things he discovered along the way.
