Wow –fuzzy photos!  But a great day doing math in the great outdoors.  Over 900 people attended Arbor Day on October 21st, 2017

Outside we presented the Fibonacci Tree model that shows how the sequence relates to tree branch growth, rabbit populations and bee genetics

Inside at the specimen and trading room we shared calipers that help show the golden ratio in animals and natural forms, we saw many people enjoy the human sundial and we measured some trees.
