Golden Ratio
Golden Ratio is a special number found in nature when you measure how plant parts like petals and seeds are spaced.
Think of it this way
When you slice a rectangle of cake, the golden ratio shows up in each piece. The short side fits into the long side about 1.618 times. Cut a small square from one end, and the leftover piece has the same shape as the whole slice. This pattern repeats in smaller pieces, just like seeds in a sunflower spread in the same spacing.
Explaining golden ratio by grade level
Count the petals on a daisy or a lily. Some flowers have 3 petals, some have 5, and some have 8. These numbers follow a pattern. Nature uses this pattern to fit the most petals or seeds in a small space.
