Why and why?

Modern "why" want to know about everything. But, learning about the world around them, they often ask adults questions that are not at all easy to give a clear answer.

Why are there seven days in a week?

What are clouds made of?

How many bones does a person have?

Why do kings need a crown?

Why don't penguins fly?

Why do trees need leaves?

The answers to these and many other questions are collected in the encyclopedia "Why and why?".

This well-illustrated edition will tell children about the mysteries of nature and ancient civilizations, about historical events and legendary figures, about animals, plants and humans.
