The author scratched his head and searched for the answers, many of which are included in this book. A child's curiosity to nature and things around is his/her desire to learn. To keep him/her interested in learning more and more, one may encourage him/her asking more "why is " and provide as many clues as possible. This is what this book is intended to help.
