Professor Poppy's Fully Illustrated 100,000 WHY Encyclopedia - Kids General Knowledge Vol. 1

#1 Bestseller in US, UK, Canada. *Updated edition with high quality black and white illustrations/pictures.*

A fully illustrated WHY encyclopedia for curious kids who want to see how the world works.
Do your kids ask endless WHY questions about science, space, animals, history, nature, the human body, technology, and everyday life?

Most children’s WHY books give short answers, tiny pictures, or long walls of text. This one is different.
Professor Poppy’s Fully Illustrated 100,000 WHY Encyclopedia turns big questions into visual answers children can actually see, understand, and remember.

Every page is built around one clear WHY question, one easy to follow explanation, and one museum-grade black and white illustration that brings the answer to life.

This is not a text heavy reference book with a few small pictures added in. It is a fully illustrated learning experience designed for curious readers ages 7+


Open any page and your child will find a big question worth exploring:

Science: Why does a magnet attract metal? Why does a candle flame point upward?
Space: Why does the Moon not fall to Earth? Why can a black hole trap even light?
Animals: Why do elephants never forget? Why do dogs wag their tails?
History: Why did the Egyptians build pyramids? Why did knights wear armor in battles?
Nature: Why do leaves change color in autumn? Why do volcanoes erupt?
Human Body: Why does your heart never get tired? Why do you dream when you sleep?
Planet Earth: Why is the Dead Sea so salty? Why do earthquakes happen?
Technology: Why can a submarine sink and float? Why does food get hot in a microwave so fast?
Food and Plants: Why does bread rise when you bake it? Why do onions make you cry?
Human Mind: Why do optical illusions fool your brain? Why do smells trigger memories?

Each answer is written in clear, age appropriate language and paired with a full visual explanation. Children are not just memorizing facts. They are seeing how ideas work.

I have always loved books that make big ideas feel simple. Growing up, I often wished complex topics were explained in a clearer, more visual, and more interesting way. That is why I write books that help curious readers understand the world without feeling overwhelmed.

Through the 'Young Explorer Series' for children, tweens and teens and the 'Big Book Of' series for adults, I focus on carefully researched nonfiction that is clear, engaging, and meaningful. I spend a great deal of time checking facts, organizing ideas, and presenting information in a way readers can connect with, remember, and enjoy. My goal is simple: to make learning feel useful, interesting, and worth coming back to.
