At our first workshop the comment was made that "it has been said that our wingspan is the same as our height. Is this true?" A few had heard about this relationship, however, no one could really present any compelling evidence aside from Leonardo Da Vinci's "Vitruvian Man". We decided to start a collaborative project to answer this question.
The most effective method for data collection would seem to use a Google Doc spreadsheet and a form to allow teachers and students to submit their data and view the complete dataset easily and quickly.
We expanded the data to allow for submitting data regarding foot and forearm length to see if a relationship existed there as well. The data shoudl be analyzed to see what the ratio is between the wingspan and height as well as the forearm and foot length to see how close that ratio is to one and to see what precision exists in the data.
