Carbon Cycle Modeling Activities
Modeling helps students understand the basic concepts of system dynamics while they investigate environmental processes that happen on spatial and temporal scales that are hard to measure directly.
Students begin their modeling experience by engaging in hands-on classroom activities (Paper Clip Analogy and Water Bucket Demonstration) of models and move quickly to STELLA based computer models using the same examples, in order to learn basic modeling principles as well as specific modeling terms and concepts.
All modeling lesson plans only require the downloadable iSee Player and not a full STELLA license, in order to make modeling accessible in all classrooms. To learn more about STELLA or the iSee Player visit, www.iseesystems.com.
Students will then explore the carbon cycle at both a local and global level using a set of computer models that vary in complexity. Two 1-box biomass accumulation models were designed to increase understanding of basic modeling and introduce students to the concept of carbon storage in biomass. Biomass model results interface directly with field measurements.
These models are followed by the global carbon cycle model, which uses more advanced modeling concepts to get students thinking about how carbon moves and interacts at global scales.
All models have accompanying activities and materials to assist student learning about carbon storage and transfer within systems and how this can change under various environmental conditions.
Modeling activities are largely designed to build on each other, but as long as basic modeling principles are understood not ALL models need to be performed in every classroom. Your use of each model should be based on your student’s previous modeling experience and overall classroom goals.
