For kids who never stop asking “why?”
But WHY?! — 100,000 Whys for Brilliant Kids — A Full-Color Illustrated Encyclopedia
Curiosity is one of a child’s greatest learning tools, and every “why?” is a chance to learn something new. This is an illustrated encyclopedia that answers the questions children actually ask — properly, with a picture for every one.

illustrated answers
Explanations that keep going until the reason clicks — no "you’ll understand when you’re older", and no stopping at what happens. Every question gets its own picture.

Your body, your home, animals, the sky and the planet, space, and how things are made.
16
unsolved mini mysteries
Questions science has not finished answering, so children can see where the edge of knowledge actually is.
19
two-minute experiments
Things to try with items already around the house. No special kit to buy.

175
full-colour pages
Short, self-contained pages and a topic index, so they can open the book anywhere and keep going.
Not a science person? You don’t need to be.
Every answer is written so that any grown-up can read it aloud and follow it. Pages are short and self-contained, and there is a topic index, so a child can open the book anywhere, find the question they want, and keep going on their own. Every page is based on science checked against space agencies, museums and current research — written clearly for children without being simplified until it stops being true.

Questions parents ask
Does it really contain 100,000 questions?
No — 162 fully illustrated answers. "100,000 Whys" is the name of this kind of children's encyclopedia, not a count. We would rather explain 162 questions properly than list thousands of one-line facts.
What age is it for?
Ages 7–12. Younger children enjoy it read aloud, and confident readers from about 8 can follow the explanations on their own. Each page stands alone, so nobody has to start at the beginning.
Do I need to know science to read it with my child?
No. Every answer is written to be understood by an adult who has never studied science. Read it aloud together, or hand it over and let your child follow their next "why" on their own.
What kinds of questions does it answer?
The ones children actually ask at the dinner table — for example, why a coat keeps you warm when there is nothing hot about it, and why a spider does not get stuck in its own web. The questions are grouped into six worlds: the body, the home, animals, the sky and the planet, space, and how things are made.
Is it accurate?
Every page is based on science checked against space agencies, museums and current research. The explanations are written clearly for children without being simplified until they stop being true. Where science does not yet have a complete answer, the book says so — that is what the 16 unsolved mini mysteries are for.
Is there anything to do, or is it only reading?
There are 19 two-minute things to try using items already around the house, with no special kit to buy, and 15 quick quizzes so children can check what they understood.
Where can I buy it?
On Amazon, in paperback. It is 175 pages, 6 x 9 inches, and printed in full colour.
