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 1: Water Cycle and Weather

This lesson emphasizes how evaporation affects precipitation which contributes to heavy rain and storms. It lays the foundation for thinking about the ways that trees can mitigate increased weather effects in urban environments like Washington, D.C. First, students discuss their past observations of evaporation and write a hypothesis to describe this phenomenon. Next, students make entries to their lab journals based on classroom instruction of the water cycle using visuals and a NASA weather video. As a class, they label a diagram that models the stages of the water cycle.

TreEAB Week 1, Lesson 3: How trees grow

At the end of this mini-unit, students will understand all the ecosystems services and value trees provide to humans every day. Students will know the biological processes of trees and the importance of native trees for providing habitat. Finally, they will acknowledge the significance trees add to our surroundings and be able to share everything they learn with others.

TreEAB Week 1, Lesson 2: The air we breathe and the water we drink

At the end of this mini-unit, students will understand all the ecosystems services and value trees provide to humans every day. Students will know the biological processes of trees and the importance of native trees for providing habitat. Finally, they will acknowledge the significance trees add to our surroundings and be able to share everything they learn with others.

Nature Works Everywhere: Urban Trees

Students will learn about how trees are an essential part of our lives with a focus on the role they play in urban areas, including energy considerations.  They then consider threats posed to trees, including non-native insects, domestic animal waste, and erosion.  Students then evaluate the potential impact of local tree conservation efforts and design a plan for their community.
