 WHY WE STUDY SCIENCE 



Problems. i. Why is some knowledge of science essen- 

 tial to us? 



2. Why is the " method of science " important? 



3. What is a science project? 



Living in an age of science. Do you ever stop to think 

 you are living at a time when science has done more to make 

 everyday life comfortable than at any other time in the 

 world's history? You sleep at night in a bed, the springs 

 and parts of which were made by machinery, and the covers 

 of which were woven by a complicated process ; you wash 

 with soap made by chemical processes ; you eat prepared 

 breakfast foods, and cook on a gas, coal, or wood stove. 

 You eat in machine-pressed dishes ; ride to school on 

 electric cars, or trains, or automobiles, the parts of which 

 were made by machines. Every part of your waking and 

 sleeping hours you come in contact in some way with de- 

 vices which involve a knowledge of science, and yet how 

 few actually know very much about the science which 

 underlies all these useful and beneficial inventions.
