2 GENERAL SCIENCE 



not live in modern conditions without his knowledge of 

 disease germs and how to eradicate them. 



The investigations and experiments in agriculture 

 have improved the farming and stock-raising industries 

 so that a sufficient quantity of food can be produced. 

 Experiments in animal feeding have led to the con- 

 sideration of human feeding and the analysis of human 

 foods. 



To live without some knowledge of the general princi- 

 ples of science is like feeling one's way in the dark. To 

 study science is to learn how to understand the environ- 

 ment in which we live and how to adjust ourselves to 

 it and how to improve our physical and social condi- 

 tion. To study science is to learn the basic principles of 

 morality. 



The important thing for boys and girls of high school 

 age is to learn how to take proper care of their physical 

 bodies so they may grow to maturity with good health 

 and with a well-developed brain and nervous system. 

 Boys and girls cannot accomplish very much even in 

 high school unless they learn how to take proper care of 

 themselves and how to adjust themselves to their envi- 

 ronment. 1 Pupils know that they accomplish their work 

 with difficulty when they have a cold, headache, or 

 indigestion. The pleasantness of school work depends 

 upon continuous effort and a knowledge of how to keep 

 free from disease. If in the first part of this course an 

 effort is made to apply the general principles to your 

 daily life, your school work will not become a burden 

 but a pleasure. 



Then why study science? 



The answer is: To learn how to live.
