Synopsis
- In this lesson, students will measure trees in their community to determine how much carbon they sequester.
- Students will use various tools and calculators to understand how tree type, circumference, density, and age contribute to the tree's ability to sequester carbon.
Subjects: Earth and Space Sciences, Mathematics
Authors: Amy Block
Region: Global
Languages: English
Teaching Materials
Positives
- Students will love getting outdoors and will develop a deeper relationship with the trees in their community.
- Learning about this important nature-based solution will help students see how impactful nature can be.
Prerequisites
- Students should be familiar with measuring circumferences and angles and should understand basic trigonometry principles.
- Students will need devices to measure the trees. They will also need to download the GLOBE Observer app before going out to measure.
Differentiation & Implementation
- If there are no trees or few trees near the school, and commuting to an area with trees is not an option, teachers can prepare tree cards with local trees, their address, distance from a building, species, height, and circumference. Students can use these cards to enter the information to find tree density and sequestration ability.
- The online Tree Identifier can help students determine what trees they are measuring out in their community.
- To learn more about how scientists determine the carbon sequestration of trees from afar, students may enjoy the article and video, Why Does This Scientist Shoot Lasers at Trees?. This can help them get a better picture of similar methods to those described in the article.
- To make creative connections, students can make data art or write poetry to demonstrate and celebrate the sequestering power of the tree they measured.
This resource presents the basic science of carbon sequestration through an engaging geometry project. Clear directions and numerous linked sources guide students in understanding how to couple field measurements with trigonometry to calculate the carbon sequestration of a schoolyard tree. This resource skillfully integrates climate science into mathematics and is recommended for teaching.
