Exploring the Golden Ratio in Nature




Investigate the presence of the golden ratio in natural objects.


  • Calipers or ruler
  • Notebook for recording data
  • Natural objects (e.g., flowers, shells, pinecones)


  1. Select various natural objects that are likely to exhibit the golden ratio.
  2. Measure relevant dimensions of each object, such as the length and width of a leaf or petal.
  3. Calculate the ratio of the dimensions and record the values in your notebook.
  4. Compare each ratio to the golden ratio (approximately 1.618).
  5. Analyze your findings to determine how closely the objects adhere to the golden ratio.
  6. Present your results in a report, discussing the significance of the golden ratio in nature.
