Student Objectives Sunday, May 03, 2015 After today’s lesson, you will be able to: Gain an understanding of the ecological importance of the American chestnut tree and; Realize the significance of the loss of the American chestnut tree population.
Warm-Up On average, an American Chestnut tree produced 6,000 nuts. On average, 100 nuts weighed 10 pounds. –What do you predict that the nuts were used for? –If Carroll County had 10,000 trees, how many pounds of nuts were produced annually?
Today’s Activities Charlie Chestnut webquest BCR about the importance of this massive tree

Economic Importance Throughout much of the range chestnut had the most timber volume of any species – Half the standing timber volume of CT Was the major source of tannin for leather production (6-11 % tannin content which conditions the leather) Chestnuts (the actual nuts)
“From cradle to casket…” The Chestnut was widely used for furniture Posts & railroad ties Telephone poles (65 feet) Construction Fuel Fine furniture & musical instruments
