Absolutely fantastic. I love when nature inspires science, especially in younger minds. In physiological plant ecology, the arrangement of branches in a spiral pattern allows for the determination of which branches share the same vascular bundles (and in turn, the same products of photosynthesis).
Just as important is that this arrangement maximizes sunlight capture by leaves, preventing them from shading each other.
13 year old copies Nature to Improve Solar Performance:
"Thirteen year old Aidan Dwyer was walking in the woods in Upstate New York in the winter and noticed a spiral pattern to tree branches. He wondered why nature used such a pattern? He concluded trees do so to collect maximum sunlight. So, he constructed two side by side solar arrays - one a typical flat-panel array that was mounted at 45 degrees, and the second, a solar array based on the Fibonacci pattern of an oak tree. He put both outside facing south. To his amazement, during the month of December, the tree design made 50% more electricity, and the collection time of sunlight was up to 50% longer than the flat panel array! "
