Activity

Determining Carbon Storage in Garcelon Bog part of Integrate:Workshops:Systems, Society, Sustainability and the Geosciences:Activities
This is a three-week lab investigating the mass of carbon stored in trees, shrubs, and peat in a local bog. The collaborative lab includes field collections of material from trees, shrubs, and peat and then analysis of organic content and calculation of the mass of the carbon pool. Laboratory work includes getting dried weights and loss-on-ignition for organic content. The groups of students who collect material in the field undertake calculations in Excel, examination of scientific literature on carbon content and root-to-shoot ratios, and area delineation in ArcGIS. Initial groups focused on one pool (i.e., shrub, tree, or peat) are disassembled and then reconfigured to bring expertise from a student's original group to a synthesis group which is responsible for the final calculation of the total amount of carbon in the bog and the write-up for the lab. The lab is designed to teach skills in collaboration and group problem solving in addition to environmental science content.
