Carbon Sequestration: Tree Measurements Lab

Encourage your students in environmental science with this hands-on lab! This Carbon Sequestration: Tree Measurements Lab guides middle and high school students through real-world data collection and calculations to estimate carbon sequestration in trees. The downloadable resource includes step-by-step instructions, data sheets, diagrams, and engaging lab activities, making scientific concepts accessible and fun. Perfect for STEM classrooms.

In this lab, students will explore the concept of carbon sequestration by measuring the size of trees and estimating the amount of carbon they store. Using tools like a clinometer and measuring tape, students will measure tree height and diameter at breast height (DBH) in a designated outdoor area.

They will then apply basic trigonometry to calculate tree height, and use a carbon sequestration formula to estimate the amount of carbon each tree is sequestering based on its size. By recording data from multiple trees of different species and sizes, students will have the opportunity to observe patterns in carbon storage and assess how tree size, species and environmental factors influence carbon sequestration.

After collecting data, students will analyze their results by creating a scatter plot graph to represent the relationship between tree size and carbon sequestration. The lab not only reinforces concepts in measurement and data analysis but also helps students understand the important role forests play in mitigating climate change. In addition to the practical skills gained, students will reflect on the environmental implications of deforestation and the benefits of preserving and planting trees as part of global efforts to combat climate change.
