Once, a long time ago, a scientist named Leonardo Fibonacci discovered the secret code the universe uses to organize itself!

We learned all about this secret code at San Pedro Elementary this week! Fibonacci discovered that flowers order their leaves according to a sequence of numbers:

**1,1,2,3,5,8,13,21,34,55,89,144…**

These numbers can indicate the number of petals on a flower, or the number of sets of petals on a flower.

But Fibonacci numbers aren’t limited to just flower petals! The Fibonacci sequence can be found in other parts of nature as well, such as the arrangement of leaves on a plant:

or the spirals in a pine cone:

or the spirals of seeds in a sunflower:

But just how, exactly, did Fibonacci break this code? We finally discovered it all came down to simple addition…

1+1=2, 1+2=3, 2+3=5, 3+5=8, etc…

…by adding the last two digits together!

The best part is that this code applies not only to petals and leaves and spirals of sunflower seeds, but to distance as well. We experimented with this concept using simple graph paper:

By connecting the diagonal corners of each square with a curved arch, we discover something similar to a seashell…

or something even more mind-blowing:

Indeed, it seems that everything on our entire planet is controlled by the number discovered by Fibonacci.

Perhaps that is why the Fibonacci Sequence is considered a **Law of Nature**!

In honor of Mister Fibonacci, we planted sunflowers, and had a delicious snack of bananas (arranged in Fibonacci spirals) drizzled with honey (produced by the Fibonacci masters — bees!), lemon juice and snipped oregano from our garden.

Delish!
