This resource is an interactive model showing the role of soil in the carbon cycle. Using arrows to represent the cycling of the carbon through the soil under a variety of conditions, it gives a visual depiction of the process. Students can use the interactive model to determine how carbon moves more in certain climates or conditions. The variables are easy to manipulate and the data is visual, including more qualitative data rather than quantitative data. The questions that are provided give the teacher a good starting point to engage students in an in-depth study of the carbon cycle. As an alternative to using this as an introduction, the resource could be used toward the end of an instructional sequence to review the concept of the carbon cycle in entirety.
