OBSERVATIONAL LESSON XVII 



PART I A SEEDLING (continued, 2nd Investigation) 

 PREPARATIONS FOR WORK 



Once more the pots that contain dwarf bean plants which have germinated in 

 sawdust will be needed (see Part I, pages 133 and 137). For purposes of studying 

 the plants in the future, it will be advisable to grow a second series of specimens in 

 pots containing soil. 



DIRECTIONS TO THE PUPIL 



(l) Take out your seedling and shake off as much of the sawdust 

 as possible from it.

SUGGESTIONS FOR FURTHER WORK IN SCHOOL 



During the week, the seedling should be watched and the process 

 by which the first bud frees itself from the se,ed-coats and makes its 

 way into the air should be seen, and if time allows, sketched. 

 Other seeds may with advantage be germinated and their manner 

 of growth compared with that of the dwarf bean.
