4 BULLETIN 305, U. S. DEPARTMENT OP AGRICULTURE. 



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 outlined. 



Review. — Review 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 winter 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.
