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 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.
