FANTASTIC FIBONACCI

I am very intrigued by the fact that Fibonacci i sequences can be found everywhere in nature.  I found it very interesting that someone would take the time to find out that objects in nature like pine cones, flowers and plants all have a mathematical sequence imbedded in them.   The Fibonacci number sequence was discovered by Leonardo Pisano who called himself Fibonacci which was short for Filius Bonacci, standing for "son of Bonacci".  The sequence has one rule that every number is sum of the two preceding numbers, ( 1,1,2,3,5,8,13,21,34…).  Here are some examples of the Fibonacci in nature:

                

As I continued to research the Fibonacci sequence I found that it is not only found in plant nature but in animal, humans, music and architecture. It is often known in nature as the golden spiral or the golden ratio represented by a series of rectangles.  

The sequence is in everyone's hands, animal shells, animal horns, sheet music and even in the Parthenon.
             

I also found a great lesson plan for teaching 4 graders about the Fibonacci sequence, the golden rectangle, and the golden sprial.  Check out "Fabulous Fibonacci and His Nifty Numbers":
