Frequently Asked Questions
Is this just another encyclopedia full of facts?
No. Most encyclopedias hand kids pages of facts to get through. Every page of 100000 Whys starts with a “why?” question that makes them curious first, so they want to read the answer, and they remember it.
What makes this different from what they learn at school?
At school, kids are told what to learn. With 100000 Whys, they pick the question they’re curious about, find the answer, and turn the page for the next one.
It’s real science that gives them a head start, without feeling like homework.
What age is it best for?
It’s best for curious kids aged 6 to 12. Younger kids love exploring the big pictures with you, and older kids can read it on their own.
My kid already does well at school. Isn’t that enough?
School covers the curriculum. 100000 Whys keeps them curious about everything else: how animals, nature, space and their own bodies work.
A few minutes a day builds a learning habit that goes beyond the classroom, and gets them off screens.
Is this good for multiple kids?
Yes. There’s no order to follow, so each child can open any page and pick the question they want answered. Siblings can read together and quiz each other with the Quick Facts.
What’s included in the book?
Every full-color page includes:
- A “why?” question that hooks their curiosity
- A big labeled picture that shows how it works
- A short answer they can finish in one go
- A Quick Fact they’ll want to tell you about
- An “At a Glance” recap that locks it in
- Common myths, busted
Covering animals, nature, space and the human body.
What if my kid doesn’t like it?
You’re covered by our 30-day money-back guarantee. Give it a month of bedtimes and breakfasts. If your kid isn’t hooked on finding out “why?”, just let us know within 30 days and you’ll get your money back.
