ANIMALS. 



Earthworm food, manner of moving, value to mankind. Relate 

 earthworm to preparation of soil for plants. Compare earthworm 

 and squirrel and rabbit, as to appearance, senses, movements, manner 

 of gettmg food. 



MINERALS. 



Power of different soils to absorb and retain heat. Kelate to plant 

 life. 



ELEMENTARY GEOGRAPHY. 



Wind that accompanies wet, dry, clear, cloudy or foggy weather. 

 Difference between April and winter rains. 



Compare course of sun with December, reason for shortening of 

 shadow; relation of length of shadow to temperature. 



NOTE. Measure a gill of corn, wheat, beans and peas; soak twenty-four 

 hours. Measure. Which absorb water? Let each pupil examine a dry and 

 soaked seed. Plant seed in different kinds of soil clay, sand and loam. Place 

 in light, shade, and dark to detect influence of light upon plant. Record time of 

 planting, first appearance above ground, dropping of exhausted cotyledons.

To compare gradual development of plant, pull up, press, and mount specimens 

 on alternate days, showing development of different parts from seed to seed. 

 Development may also be observed by being placed in bottles of alcohol. Care- 

 fully date each specimen. Plant acorns in yard. 



Fill a large sponge with flaxseed and place in a shallow dish filled with water 

 Keep moist. 



Mark off a yard square and observe the work of earthworms. Each morning, 

 carefully collect castings and measure. Some idea of amount of work being 

 done in renewing and fertilizing soil. Study structure, food, habits, senses; 

 adaptation of structure to environment. Pupils should be led tor see that each 

 plant and animal is adapted to perform its function in the economy of nature. 



Relate April showers to increasing temperature greater heat, greater evapora- 

 tion, consequently greater condensation. 



MAY. 



PLANTS. 



Reason for early appearance of wild flowers; food; protection and 

 color of spring flowers; advantage of color; unfolding of buds. Vena- 

 tion.
