The Vitruvian Man was first drawn in 1492 by Leonardo Da Vinci, based on the work of a Roman architect, Vitruvius. The two man-superimposed drawing states that 9 body ratios are true, such as a person's arm span being equal to their height. In this lab activity, students are on a mission to see if that is true! They will measure their own height and their own arm span and see how well they fit Leonardo's Theory. Students will collect data on themselves for each of the 9 ratios. Great for Anatomy and Physiology classes!
