cost of these, and find, approximately, what our daily

LESSON XLIV 

 HOW OUR BODIES GROW 



Why do we get hungry ? About how often do we get hun- 

 gry? What good does the food that we eat do us? Com- 

 pare human food and plant food as illustrated in the study 

 of germination. When are we most hungry, after going on 

 an excursion or long walk, or when we have been in the house 

 all day? Which will eat more, the man who works hard, 

 or the one who exercises little? What, then, does exercise 

 use up which it requires food to restore ? 



Do we eat more in cold weather or in warm ? What kinds 

 of food do we like best in winter ? in summer ? Food builds 

 up our bodies and keeps us warm. Discuss wholesome and 

 unwholesome foods; the danger of eating too fast and too 

 much ; and the necessity of chewing well our food, and there- 

 fore, of having good teeth. 



In this connection some lessons may be given on table eti- 

 quette : the proper use of knife and fork, spoon, napkin, etc. 



Why do we prefer certain foods ? When things taste good 

 to us, what are we likely to do that will injure us? If 

 things did not taste good to us at all, how might our bodies 

 be injured? Name something that is sweet, sour, bitter, 

 pungent, saline, etc. Let the pupils taste things having 

 these flavors. Some things impair our sense of taste. We 

 should avoid using much pepper, spices, and condiments.
