i-Tree Unit Lesson 7: Tree Planting Design

In Lesson 6: Tree Adaptations, students identified at least 5 different tree species based on their ability to adapt to the two main climate factors of their project areas: precipitation and temperature. As a control, students also identified tree species outside of the recommended USDA Hardiness Zone to compare results. This tree data was modeled using i­Tree Design to determine which tree species are more likely to survive. Students noted the adaptations of the trees that are best suited for the precipitation and temperature of their area.

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.

Build a Tree

This activity (on pages 13-18) has learners build a model tree and then figure out how to make their tree stand up by itself.  This illustrates how the tall rain forest trees adapt to support a huge trunk and heavy branches, while also sending their roots out instead of down.

Species that Cause Change in the Environment-Beneficial vs. Harmful (Activity #1)

A 30-minute presentation focuses on how some species (native and introduced) are beneficial to the environment, while others (native and introduced) are actually detrimental (harmful) to the environment. 

The presentation is followed by a researching activity where students visit several specified websites and complete a handout and final report on their findings.
