Activity 8: Counting Carbon
Overview
This activity helps students understand carbon sequestration in trees and teaches them how to compare carbon sequestration potential for different land uses. Students measure trees near their school and calculate the amount of carbon stored in individual trees. Students then calculate the carbon sequestration potential of a pine forest and compare that to various land-use types in their state. By estimating the amount of carbon emitted by human activities in their state, students can discuss their forest’s ability to sequester atmospheric carbon and potential ethical implications of having excess carbon or untapped sequestration potential.
