38 NATURE STUDY ,BY GRADES 



at night? Point to where the sun rises; to where it sets. 

 The first direction we call what ? The latter we call what ? 

 Which is north ? and which is south ? Recall work already 

 done, and impress these directions upon the minds of the 

 pupils as may be needed. 



Notice each day for a week or two if the sun rises in exactly 

 the same place. Likewise notice the place of sunset. In- 

 struct the pupils to make their observations from the same 

 window or point of view each time, and notice what moun- 

 tain peak or natural object is near the place where the sun 

 rises or sets. In a week or two they should be able to dis- 

 cover that the sun is moving south. 



By using a shadow-stick, the. pupils may find if the sun ? s 

 position at noon is changing. How ? Trace through the sky 

 with the finger the daily path of the sun. 



A SHADOW-STICK 



A shadow-stick may be made by fastening to a horizontal strip of lumber fifteen inches long, 

 an upright four inches high at right angles with it. Graduate the horizontal outward from 

 the angle, indicating inches, halves, and quarters. In using the shadow-stick, place it in 

 a horizontal position with the upright to the south at noon. The length of the shadow is 

 seen at a glance. 



The sunbeams, entering a south window, may be used 

 for the same purpose. Each Monday noon, just before 

 school is dismissed, call attention to the length of the sun- 

 beam which falls upon the floor from the south window. 

 Drive into the floor a brass-headed tack, marking its length.
