Procure several ears of corn and note the following 



points: shape of the 

 ears, whether cylindrical,

 color of the grains, size

 of the cob, etc.

 grains to each row. Do 

 all ears agree in this? 

 How many rows to the 

 ear? Are all ears alike

 will not often be found. They are known as sports.
