THIRD GRADE. : 
In this grade the population studies in a general way are continued 
with all plants and animals. More particular studies are made with 
garden crops. Additional work with annual wild flowers and weeds 
is undertaken. Particular attention is given individual plants. The 
bird studies are continued in greater detail, and additional work is 
undertaken with domestic and economic wild mammals. Lessons 
with particular animals are outhned. 
PLANTS. 
Review.—Keview the pupils on recognizing at sight trees, flowers, 
and garden and field crops. This recognition work should be carried 
further than with the preceding grades. Trips to the forests and 
fields should be planned for this purpose. Children are easily inter- 
ested in things that are attractive. Take advantage of this and 
direct their attention to plants that are attractive in foliage, flowers, 
or fruit this month. Have pupils make lists of trees, flowers, and 
garden and field crops they are able to recognize at sight. 
Assigned work.—What garden crops are planted this month? 
Why can they be planted in the fall? Do they continue to grow 
during the wimter months?) What garden plants are blooming this 
month? When were they planted? Why? What garden crops 
are maturing seeds, roots, or tubers this month? When were they 
planted or transplanted? Were the plants started in the open or 
in hotbeds?) Why? Will they grow during the winter months? 
How are their plants reproduced—by seed, roots, or tubers? [If left 
to propagate themselves how would the seed be distributed? Answer 
these questions with regard to okra, tomatoes, sweet potatoes, and 
pole beans. : 
Are there any wild flowers or weeds blooming or ripening seed on the 
school ground, in the garden, on the roadside, in the pastures, or in the 
fields? How do they reproduce—by seeds, roots, or underground 
stems? How are the seeds scattered—attached to clothes of people 
or skins of animals, by bursting pods, by flying appendages, by birds, 
or otherwise? Answer these questions with regard to beggar lice, 
bitterweed, goldenrod, crab grass, milkweed. 
List and copy in the class notebook the names of wild flowers and 
weeds that bloom or mature seed this month. (If you can not learn 
the names of any that you find, mail them to the State agricultural 
college with the request that they be identified for you.) 
Encourage pupils to have fall and winter garden plats either on the 
school yard or at home. While caring for the garden plats have them 
observe seeds in process of germination and learn to name and locate 
the parts of plants—roots, stems, leaves, flowers, seeds.
