Day Night Sunrise. 9 



1 6. I shall now show on the blackboard how 

 day and night are caused. The lamp represents 

 the sun, and the apple stands for the earth. The 

 sun gives light to that side of the earth which 

 is opposite it, as is shown by the bright side of 

 the apple, which represents day. The side turned 

 away from the sun is dark there it is night 

 If the earth did not turn on its axis (or rotate) 

 we would not have night and day as we now 

 have them. 



To oe drawn on the blackboard to explain the succession of 

 Day and Night. The lamp represents the Sun ; the apple, 

 the Earth; the needle .on which the apple turns represents 

 the Axis of the Earth. 



(The teacher should now and then tell the children a 

 story touching any of the points in the lessons.) 



1 7. When you say the sun rises in the east in 

 the morning, it only appears to rise. It is not 

 the sun which moves from the east upward and 

 nearly over your head, and then down in the 

 west in the evening. It only appears to do so.
