Science knows no country, because knowledge belongs to humanity, and is the torch which illuminates the world. Science is the highest personification of the nation because that nation will remain the first which carries the furthest the works of thought and intelligence.
— Louis Pasteur, French chemist
After reading this book, you may find yourself wishing there were more activities to try. Perhaps the questions you were able to address by doing the experiments here only brought up more questions for which you don't have answers. If either is the case for you, then congratulations! You are a scientist!
You see, scientists are never satisfied that they know all there is to know. Each answer brings more questions. They are filled with an insatiable desire to know more about their world. When they can't find the answers in a book, they figure out ways to predict what the answers should be and then test those predictions, according to the Scientific Method. But would you like to know a secret? Scientists aren't the only people who use this method. Lawyers, doctors, bankers, teachers, stockbrokers, and real estate agents do, too. In fact, you'd be hard-pressed to find anyone who doesn't use the principles of the Scientific Method in his or her daily life.
So welcome to the world of science! Ask questions; dig deep to find answers; don't accept “I don't know” for an answer; and, most of all, have fun (and be safe!) doing it. For it is in the search for answers that the true wonder and beauty of this world will be revealed to you.
