Encyclopedia for the Curious. How and Why?

Modern-day "little curious ones" want to know about everything. But as they explore the world around them, they often ask adults questions that are not at all easy to answer clearly.
Why are there seven days in a week?
What are clouds made of?
How many bones does a human have?
Why do kings wear crowns?
Why don't penguins fly?
What are leaves for trees for?
The answers to these and many other questions are collected in the "Why and How?" encyclopedia. This well-illustrated edition will tell children about the mysteries of nature and ancient civilizations, historical events and legendary figures, animals, plants, and humans. Written with humor, in a lively and engaging way, the encyclopedia will become a go-to book for any inquisitive child interested in learning about the world they live in.
