THIRD GRADE WINTER WORK 







LESSON XXI 



CHANGES IN ANIMAL COVERING 



What changes do most of our winter dwellers make in their 

 coverings in the fall? Mention as many as possible that 

 put on a heavier, warmer coat. When does this coat change 

 for a lighter one? Discuss fully these changes in domestic 

 and wild animals; and the necessity for it. If possible, 

 get samples of the summer and winter coats of the same 

 animal. 



Do any animals change the color of their coat? Account 

 for this. Discuss the weasel, which is white in winter and 

 gray in summer. Some rabbits also change color as a means 

 of protection from enemies. Birds often make similar 

 changes. The snake, toad, and other animals shed their 

 skins at certain periods. Account for this. 



The structure, changes, and uses of the various coverings 

 of animals will afford material for many interesting lessons 

 according to the knowledge of the teacher and the oppor- 

 tunities of the pupils to do observation work along this line. 



LESSON XXII 

 MIGRATORY ANIMALS 



Mention animals that leave us for the winter and return 

 in the spring. During the fall months a record of the birds, 

 insects, and other animals seen each day should be kept, 

 and thus the time of their disappearance discovered.
