What Causes Autumn Colors? 



The autumn colors are due to the breaking up of the chlorophyll 

 which gives different species of trees their peculiar colors. The 

 brightest colors are produced in swamps where it is cool • and 

 moist before the frost occurs. A frost turns leaves brown and 

 not into bright colors.

In thinking of chemicals we are too apt to have a vision of 

 laboratories, bottles, and labels. If our perspective stops there 

 we do not have the broad outlook that chemistry should give us. 

 We see symbols and not ideas. The symbol is only a means to an 

 end. Our educational courses should not stop with the means 

 of seeing, these tools should be made to reproduce ideas.
