EXERCISE 24 

 WHAT AKE THE PARTS OF A FLAME? 



Materials. A wax, tallow, or paraffin candle ; matches. 



Directions. Light the candle. Find and describe three layers, or zones, in the candle flame. The 

 inner zone is dark ; the middle zone is bright ; and the outer zone is pale blue and forms only a thin 

 layer over the surface of the flame. 



Make a diagram of a flame showing the principal facts. This should be of natural size or larger, 

 and may be colored with crayons or water colors. Label the parts. 



Additional problem. Does an illuminating gas flame show the same parts as the candle flame ? Does the 

 Bunsen flame ? Does the kerosene flame ?
