SECOND GRADE WINTER WORK 95 



vegetation become more scarce, and the birds go south where 

 their food can be found. Help the pupils to develop 

 this thought from what they have noticed. Do birds of 

 prey migrate? 



The absence of the butterfly may be explained in a similar 

 way. Its food is gone, and it is poorly adapted to stand 

 cold, stormy weather. Can it travel well? Will it follow 

 the birds ? Hunt cocoons and keep them till spring. Also 

 account for the disappearance of the frog, lizard, house 

 fly, mosquito, snakes, etc. 



Occasionally a caterpillar may be found and placed where 

 the children can see it make its cocoon. 



Note where typical kinds of animals go, and how they 

 spend the winter, and why. Discuss their intelligence, 

 ability to travel, and physical structure, and bring out how 

 they are adapted to their respective methods of passing the 

 winter. 



LESSON XIX 

 PREPARATION FOR WINTER PLANTS 



A field lesson, where pupils can examine the conditions of 

 both wild and cultivated plants, should form the basis of 

 this work. Many changes, made necessary by winter con- 

 ditions, can be discovered, and their relations traced. The 

 following are a few that the children may be led to see : 

 The leaves have fallen from most shrubs and trees. Why? 

 New buds are formed near the old leaf scar. What for? 

 Some buds are covered with scales, some with fuzz, and 

 some with gum. Why are they thus protected? Measure 

 the growth the twigs have made this year. How can you 

 tell? What trees are rapid growers? Which grow more
