Description

You are one of the very luckiest of people-to be growing up in the Age of Science. For a long while, boys and girls used to say, "I wish I were a pioneer," or "I wish there were something left to discover." Nowadays, it is perfectly clear that science offers a great variety of new things to discover and that many of the new pioneers will be scientists.

Physical science is the study of matter and energy. Chemistry is one of the physical sciences.' It teaches us much about the different kinds of matter and how they behave. It teaches how different chemicals react with each other, so that you can tell in advance what will happen when you mix certain chemicals together. This knowledge has helped chemists decide what fuels to use to propel rockets and push satellites into space. But you cannot work with nuclear reactors or rocket fuels until you first learn the fundamental facts of chemistry. This book will help you to do just that.

Remember that you didn't learn to roller-skate, or to ride a bicycle, until you could balance yourself on your feet. You cannot devise new chemical reactions until you can balance chemical equations. It's fun to mix things in a laboratory and to guess or predict the results. You may not always be correct in your predictions, nor will you always be correct in your mixing, but it will always be fun to account for every single atom involved in a chemical reaction. You will learn how to do this gradually, as you do the experiments in this book. You must remember to follow the safety rules, to be neat and careful, to avoid contaminating your chemicals, and to be especially conscientious about reporting observations accurately. A true scientist would never put away a dirty test tube or falsify a report.
