Objectives:

     Observe the structure of a flower.
     What function does each of these structures serve?
     Observe the variety of flower shapes.
     To identify the parts of a flower reproduction stage: pollination.

Materials needed:
        
     gladiolus flower, forceps, hand lens, dropper, water, microscope slide, 
     scalpel, coverslip and microscope.

Strategy:

     Displayed an illustrative drawing of the structure of a flower on the 
     chalkboard.  Referring to the display; students and teacher labeled each 
     part of the flower. 
     
     Students and teacher reassembled a disassembled artificial flower;
     labeled the parts as we reassembled the flower.

     The class was given live flowers for dissecting.  Some dissected parts 
     were placed on diagrams of flowers. 
                                                            
     Class members were informed that in flowering plants, it is the transfer of 
     pollen from an anther to a stigma.
     Most flowers are pollinated by insects.  Some by animals, wind or birds.
    
Performance Assessment:  
  
     The assessment would give the result of the findings of parts of the 
     flower.  The live flower revealed more parts than did the artificial 
     flowers, with the exception of the pistil.
       
     Presently, students have become familiar with the basics of the flower.
