It's an incredible little book! It demonstrates the science history as well as basic science concept and methodology in a well-organized way. Science begins with curiosity, what drives scientists to observe, gather evidence and use logical thinking to prove or generate an idea. Scientists use not only their heads, but also their hands. Scientists do a lot of experiments and sometimes conclude them mathematically, etc....
This book is very inspiring and encouraging, my 4 year old even found that he and scientists have something in common.
