NATURE STUDY 



Yes, that is the way that it seems, but really we are 

 travelling round the sun. 



Illustrate this by causing a globe Avith a small portion 

 of it covered with black court plaster to revolve around 

 a lamp until at last the plaster catches the light. 



Recall to their minds the similar phenomena familiar 

 to them in the telegraph poles, fences, houses, which 

 apparently rush by us as we gaze out of the windows of 

 a moving car. 



Phaethon driving Apollo's car. 



"What does the sun give us ? How does it send us 

 light and heat ? Illustrate by throwing a pebble in 

 water, by shaking the room or desk, by the voice. 

 What good does the light do? heat? 



To determine the apparent course of the sun and the 

 consequent daily and seasonal variations in temperature 

 mark each week at same hour the distance which the sun 

 shines into the room. This may be done by driving a 

 tack in the floor. During December the sun will come 

 farther and farther into the room until the twenty-second.
