An illustrated encyclopedia built around the questions children actually ask. Why is the sky blue? Where does rain come from? Why do we dream? The 100,000 Whys format has been a staple of children's reference publishing for decades, and this edition keeps the same idea: a short, clear answer to each question, paired with an illustration that does the explaining rather than decorating the page.
What is inside
- Science and physics — light, sound, heat, motion and simple machines.
- Nature and animals — habitats, behaviour, plants and the seasons.
- Space and Earth — planets, stars, weather, volcanoes and oceans.
- The human body — how we breathe, sleep, grow and heal.
- Everyday life — food, machines, transport and the technology children see daily.
Why the question-and-answer format works
A child who is curious about one thing rarely wants a whole chapter. Each entry stands on its own and takes a minute or two to read, so the book can be picked up and put down without losing the thread. Related entries sit near each other, which is what pulls a child from one page to the next.
Who it suits
- Ages 6–8 — read together; the illustrations carry most of the meaning.
- Ages 9–12 — independent reading and homework support.
- Families who want a screen-free option for curious questions at the dinner table.
Good to know
- Text is in English.
- Full-colour illustrations throughout.
- General-interest reference for children. It supplements school material rather than replacing a curriculum.
