i-Tree Unit Lesson 4: Carbon Cycle

In Lesson 3, students concluded that carbon dioxide impacts the ecosystem by heating the air, resulting in more evaporation and transpiration. Students also gained an understanding that human activity (i.e., their morning commute to school) produces carbon dioxide. In Lesson 4: Carbon Cycle, students explore the ways that carbon is both produced and sequestered.

i-Tree Unit Intro: Tree Inventory - Map Your Schoolyard

Students walk around their schoolyard to conduct a Tree Inventory that assesses land usage and the existing trees. They note the different ways that the land is being used (i.e, residential, commercial, parks) and draw these on the map in their Lab Journal. They also draw all of the existing trees on their school’s block. In addition, students collect data about each tree (i.e., evergreen or deciduous, condition of tree and the impact on the area it is growing).
