What do flower petals, pinecones, and rivers have in common? Math! That's right - math reveals itself in the most unexpected places. Consider this: Although well-known in the field of mathematics, the numbers of the "Fibonacci sequence" are also frequently found in the natural world, such as in the number of petals on a flower and the number of spirals of a pinecone. Similarly, "pi"  appears in many other phenomena. Did you know that pi can be used to calculate the length of a meandering river?

This video from “NOVA: The Great Math Mystery,” gives students a chance to peel back the layers and see how math reveals itself across the natural world.
