i-Tree Unit Lesson 5: Canopy Assessment Lab

In Lesson 4: Carbon Cycle, students explored the ways that carbon is both produced and sequestered, and described how they would reduce carbon in the atmosphere (using text and visuals). As a follow up to calculating their personal carbon footprint in Lesson 3, students will calculate the carbon footprint of their zip code. Next, they will use the i­Tree Canopy online application to assess the area of tree canopy in their defined area and how much carbon is already being captured by the existing trees.

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 Lesson 3: Carbon Footprint

Through the experiment conducted in Lesson 2: Evaporation Lab, students concluded that higher atmospheric temperature causes an increase in evaporation which results in more precipitation. In Lesson 3, students first calculate the carbon footprint of their morning commute to school to realize that different modes of transportation produce varying amounts of carbon dioxide  Next, they conduct an experiment to explore how producing carbon dioxide impacts the ecosystem.

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).
