HES Activity 4.3 Differentiation

  • Identify locations in the room as the two carbon pools, then have students play the role of carbon atoms moving between the two pools.
  • Project the graphs onto a white board and demonstrate how to fill them in after each move.
  • Have students work in pairs and fill out one worksheet for each pair.

Demonstrate how to use one scenario card with the class before dividing them into pairs or groups to discuss their cards. You may also want to draw circles on the board to represent the biomass (organic) and atmosphere (inorganic) pools that students can use to illustrate the results discussion or ask questions.
