EXERCISE 35 

 WEEDS 



Object. To become familiar with the weeds in vicinity of the school, 

 and their control. 



Material. Each member of the class should be required to collect ten 

 weeds before this exercise is given (Fig. 42) . Each specimen should include 

 the root, stem, leaves and either the flower or seeds or both. By mounting 

 the best of these specimens the school may obtain a valuable collection. 

 This collection may be supplemented by conducting a field trip for the pur- 

 pose of identifying and collecting weeds. Save the weed seeds for later use. 



Directions Each student should describe each of his ten weeds accord- 

 ing to the following outline. After describing his own he should describe 

 weeds collected by other students. Thus each student may make a fairly 

 complete inventory of the weeds in the locality of the school.

The Weed Club. A weed club has been successful in some schools. 

 The object of such a club is to rid a locality of weeds. Each member of the 

 club chooses an important weed and agrees to destroy a certain number each 

 day of the growing season. The club may also spread control information 

 and may add to the school weed collection. 



Weed Contest. The object of a weed contest is to determine how many 

 students can identify unlabeled seed mounts in the school collection.
