In this activity, students will measure the circumference of a tree, use a biomass chart to determine the mass of the tree, and then calculate the amount of carbon that the tree has stored.
This activity uses easy-to-follow directions and offers explanations for each step.
Students will have a chance to practice reading a graph and performing calculations for a tree in their own community.
Students should have a basic understanding of photosynthesis.
Teachers will need to provide students with a tape measure and a printout of the graphs on pages 4 and 5 of the PDF.
This video resource pairs with this activity, so students can also watch the video before completing the activity.
After calculating the stored carbon in the tree, students could compare it to annual global carbon emissions data and calculate how many trees it would take to sequester that much carbon.
Students could turn their data into an awareness campaign by making a video explaining how much carbon each tree has stored and placing a QR code on the tree so that people can scan it to find the video.
