192 NATUKE STUDY 



Earthworms may be kept in a pot in the schoolroom, 

 fed on cabbage leaves and other vegetables, of which 

 they are very fond. The pot should be kept fairly 

 moist. Cover it with a piece of glass and black paper ; 

 then when the latter is suddenly removed, they may be 

 seen at work. 



Strangely enough, children do not seem to object 

 to touching earthworms, but bring in willingly many 

 specimens. They should not be allowed to handle 

 them, however, on the earthworm's account, not on 

 theirs. 



If the teacher shall deem it advisable, each child may 

 have a specimen to study, keeping it in a small box 

 partly filled with moist earth. 



About how long is the earthworm? Where is it 

 largest round ? What difference between the head and 

 tail end ? How does it move ? What does the saddle 

 look like ? What color is the skin ? What difference 

 in color between the upper and lower sides ? Between 

 the head end and the tail end ? Why ? 



Notice the blood-vessel in the back. Which way does 

 the blood travel ? How many beats per minute ? 



In the study of the birds procure nests and stuffed 

 birds if possible. If not, colored pictures will answer. 



In each case let the children determine the habit 

 and the food of the animal by the study of its beak and 

 feet. 



Get from them their own experience and observation 

 of the particular bird under consideration, and add to 

 these your own.
