Activity 4.2: Carbon Pools and Constant Flux Simulation (30 min)
Target Student Performance
Students describe the relationship between pools and fluxes in an online computer model: changes in pool sizes depend on balance among fluxes.
Resources You Provide
- Computer (1 per student or pair of students)
- 4.2 Carbon Pools and Constant Flux Simulation PPT
- Constant Flux Simulation
- 4.2 Computer Model for Constant Flux Worksheet (1 per student)
- 4.2 Grading the Computer Model for Constant Flux Worksheet
Print one copy of 4.2 Computer Model for Constant Flux Worksheet for each student. Prepare computers for each student or pair of students to run the Constant Flux Simulation.
During the discussion after the simulation, be sure that students recognize that the patterns are the same as in Activity 4.1 even though there is a larger number of atoms in the system. Use 4.2 Grading the Computer Model for Constant Flux Worksheet to grade students' work.
