Calculate the Carbon Storage of Sanctuary or Schoolyard Trees

Students will learn to measure a tree, calculate how much carbon it holds, and then calculate the carbon storage capacity of Wachusett Meadow's forests or schoolyard trees. Students will determine how many sanctuary or schoolyard trees are needed to offset their carbon footprint, as well as national and international footprints. If time, students can discuss the pros and cons of formal carbon offset programs. This program is very hands-on and involves problem-solving, the acquisition of some real-world forestry skills, a bit of tree identification, and lots of math calculations.

2.5 to 3 hours is the ideal length of time for this program. This program pairs well with the Climate Change Hike program.

*This program can be taught outside in your schoolyard following all COVID-safe guidelines. Or, invite one of our experienced teacher naturalists into your online class.
