In this lesson, students learn about carbon sequestration and measure trees on their campus to assess the amount of carbon they contain.

Step 1 - Inquire: Students use their knowledge of photosynthesis to consider how human activities, specifically land use, have disrupted the carbon cycle.

Step 2 - Investigate: Students take a walk to select a tree on campus or in the neighborhood, measure the DBH of their tree, and enter their data onto a spreadsheet to obtain the biomass and mass of carbon sequestered.

Step 3 - Inspire: Students discuss the cultural value of forests and their ability to act as carbon sinks and take action by choosing to protect trees through non-profit advocacy groups or by educating others.
