Looks at how spirals form in nature when cells reproduce in a flower, for example. An interactive lets students try entering different values to see if they can make a spiral pattern with no gaps. The correct figure would be the Golden Ratio. Its relevance is explained next and how it relates to Fibonacci Numbers. Other examples of the Golden Ratio in nature are described, as well as the Golden Angle. Includes an activity for recording observations of spirals in nature.
