GERMINATION OF SEEDS 2jr 



gather the corn from a carefully measured area (at least ^ acre). 

 First weigh the ear corn and then compare your estimates with the 

 actual yields. Be sure to record your estimates in your notebook, where 

 you can later write the actual yields. 



NOTE TO THE TEACHER. Have the pupils make a home-made 

 seed tester by following the directions in the text or by dampening, 

 many folds of old newspapers kept in a small tight box. In it let them 

 place fifty or one hundred seeds of as many kinds as they can find near' 

 home. Let them pick out the largest and smallest seeds of wheat, 

 radish, or peas. Place both sizes in different parts of the germinating; 

 box or plate and notice which produces the largest shoots. The in- 

 terest of parents may be enlisted by having the pupils make tests to- 

 determine the percentage of germination of the seeds of vegetables or 

 field crops that their parents expect to plant.
