XXVI. SPROUTING BEAN 



Material. Some beans that have been soaked in warm water over 

 night, and some sprouted beans. Plant some beans next to the glass in 

 a tumbler of moist sawdust, so that they can be easily seen while they 

 sprout. Wrap thick paper around the glass to keep out the light. Give 

 the lesson when the beans are breaking through the surface of the soil. 



Observation. -- What part of a bean plant first 

 appears above ground ? When the upper end of a 

 bean plant appears, how many leaves has it ? How 

 great a part of the bean that was planted comes up 

 with the new plant ? How large is the stem of the 

 plant ? What becomes of the outer skin of the bean ? 



Split open a fresh bean and find in it the first pair 

 of leaves that will appear above ground. How great 

 a part of the bean do the leaves form ? Find the be- 

 ginnings of a stem and of the second pair of leaves. 

 In what part of the bean are they ? How large are 

 they ? Does the stem point toward the hollow, or 

 toward the back of the bean ? 



Drawing. Draw a picture of the inside of a split 

 bean. Make this picture large enough to show the 

 young plant that is in the bean. Draw also a picture 

 of a bean plant that has just come up. 



Composition. -Write a paragraph describing a 

 young bean plant, and another paragraph about the 

 plant as it appears in an unsprouted bean.
