It soon became clear that human made objects very often follow straight line and right angle patterns, while growing things very seldom do.
We discussed straight lines and right angles where
We discussed straight lines and right angles as they occur in nature and in our own bodies -- arms held out at 90 degrees from the body, gravitational force perpendicular to the surface of the earth, cubic salt crystals, straight-grained linear conifer trees, the east-west turning of the earth and the orthogonal north-south axis -- and talked about alternative geometries to think and act with, as seen in the growth patterns of plants. As a follow-up, the students read this article, Ancestral genres of mathematical graphs, and continued the discussion through class blogs.
Some of the students have come back to the Orchard Garden as volunteers or simply as a quiet place for study since our field trip.
