THE DIRECTION OF SUNRISE 



11 



Tile position of the sun varies from day to day, the 

 sun being farther to the south in winter than in sum- 

 mer. The sun rises in the east and sets in the west on 

 two (Jays only. What are those days? How can you 

 find out? 



Experiment 6. *To Record the Direction of Sunset. 



a. Use the apparatus of Experiment 5. and arrange 

 your results in the form of a table. Direction should al- 

 ways be measured from the North-South line whenever 

 we wish to be exact. If the direction is just east or just 

 west, we say so. All other directions are given as the 

 number of degrees they are from the north toward the 

 east or west, and from the south toward the east or west. 

 If the direction of sunset is 80 degrees from the north, 

 the record should be : N. 80 W. If it is 70 degrees from 

 the South, the record should be : S. 70 W. What is the 

 difference between N. 90* W. and S.90 W? 



b. The table for the record should be as follows : 



Once a week is often enough to take the observations. 

 Try it at home and see how your results compare with 

 those of the other pupils. 



Review Questions. 3. 



1. Begin with the direction north, and name the 

 four principal directions, and the half-way directions, 

 all the way around the circle, starting toward the east 

 Now repeat starting toward the west. 



2. Where did the sun rise this morning? 



* This experiment e'art be performed only at home.
