STORY TEST 



GEORGE WRITES ON THE METHOD OF THE SCIENTIST 



Read carefully and critically. List all the errors and suggest 

 corrections. 



I want to be a scientist when I grow up so I have decided to 

 form the habit of thinking like a scientist. First of all, a scientist 

 always makes his mind up as to whether a thing is so or not and 

 never changes it. That is the way to successfully solve problems. 

 You must try to see the end or reason for doing certain things. It 

 is not wise to have an open mind and listen to everybody's views. 

 It is much better to have a mind of your own and not allow your 

 ideas to be changed by anyone. The scientist may find out the 

 truth by means of evidence, but the easiest way to be sure to have 

 the right evidence is to ask someone rather than to depend upon 

 your own experiments or experience. If the Indians had only 

 made some practical use of their ability to observe accurately, 

 we might credit them with using reason. The scientist always 

 tries experiments and asks questions of nature to see if he is right 

 in his problem. I would never study books in science for you 

 cannot learn anything from books. I would always make experi- 

 ments, and if they came out the way I thought they ought to come 

 out, then I would believe them. In other words, a scientist always 

 believes his senses. 



PROBLEM II. WHAT IS OUR ENVIRONMENT AND HOW 

 DO WE USE IT? 



What Are the Factors of Our Environment ? Just what 

 do living things need in order to live ? Growing boys and 

 girls use air in breathing, drink water, eat food, are com- 

 fortable at a certain temperature, need light, and also 

 need something to live on, the earth. With our present
