Poker Chip Model: Global Carbon Pools and Fluxes
This activity helps students visualize and model a commonly published diagram of global carbon pools and fluxes. Students create a scaled 3-D visual of global carbon pools and net fluxes between pools with anthropogenic influences. The relative sizes of the pools can be modeled with stacks of poker chips, rolled columns of printer paper or similar. The fluxes can be represented by bingo chips, pennies or similar. Supplemental discussion questions guide students through considering the forms of carbon in pools, key carbon transforming processes associated with fluxes, and the implications for climate change.
