Synopsis
- This math and science activity about photosynthesis and calculating the biomass of trees includes a video and a linked worksheet for students to complete a similar investigation on their own.
- The video leads students through a fast-paced investigation to determine the mass of a tree, where the mass comes from, and how much carbon dioxide a tree has absorbed in its lifetime.
- Students will learn what percentage of a tree is made up of carbon, how a tree’s biomass can be estimated using only the diameter of the tree’s trunk, and how to calculate the amount of carbon dioxide a tree has absorbed.

Teaching Materials
Positives
- The linked activity contains a written recap of the concepts covered in the video and is located in the description of the video.
- The linked activity provides students with a chance to practice estimating the amount of carbon dioxide sequestered in a tree in their own community.
Prerequisites
- Students should be familiar with basic chemistry to understand the discussion of the mass ratio of carbon dioxide to carbon.
- Students will need to understand the relationship between the circumference and the diameter of a circle.
- The video provides a short description of both photosynthesis and allometry, but students unfamiliar with the topics will need more background knowledge to fully understand the concepts.
Differentiation & Implementation
- Connections can be made with math classes that are learning about geometry, graphing, or data collection and analysis.
- Biology classes can use this video and activity to hook students before a lesson about photosynthesis or as a lab exercise after learning about the carbon cycle.
- After estimating the amount of carbon dioxide sequestered in a tree, students can use a carbon footprint calculator to estimate their own carbon footprint and then determine how many trees it would take to cancel it out.
- Advanced students can research why different tree species have different biomass estimations, even when their diameters are the same.
