How Much is That Tree is a series of experiential projects for STEM multidisciplinary learning on the theme of valuing trees and their benefits to the ecosystem. 2nd to 5th graders (and older students) collect simple data from local (or imagined) trees and enter into the iTree calculator to obtain the dollar value of the trees contribution to the ecosystem in terms of stormwater reduction, air quality improvement, CO2 sequestration and potential energy reduction to neighboring buildings. This study is set in context with some short experiential exercises: draw My Favorite Tree, Goods from the Woods, Tree Functions and Tree Identification. Students can then continue the tree theme with STEM extensions such as modelling trees and service-based learning - such as setting up a tree nursery or caring for trees in a schoolyard.
