Here’s our spiral model in NetLogo (the most flexible model) and also in Python. Here’s one of our spiral models in Scratch. Below are screenshots of the code in Scratch.




Here’s our movie that applies this model of golden angle spirals to a craft with pinecones based on our computer model of spirals in NetLogo and a similar spiraling model in Python. We see such golden spirals in sunflowers, daises, dandelions, pine cones, pineapples and more.
There is another way to make golden angle spirals which we show here. This version of the model helps show how the golden angle, approximately 137.5 degrees, fills space.


With the model you can connect the dots with lines, forming triangles, to help show how each golden angle turn (137.5 degrees) creates a point that fits in between previous points.


















This is also true of daisies and dandelions, the number of spirals are Fibonacci numbers.
