Place the game cards onto the proper storage area.
Choose a game piece and place it on Plants.
Decide who goes first by rolling the dice.
Pick a Plant card and find out your next destination. Roll the
dice to see how many spaces you move toward your
destination. Return the card to the bottom of the Plant pile.
• Keep rolling until you get to your destination. When you arrive,
stop there. You’ve been stored!
• On your next turn, pick a new card from your new storage area
then roll to see how far you go.
• You get a point each time you get back to Plants. The person
with the most points by the time the instructor says to stop
playing wins!
Questions to consider
• What is the importance of plants in the carbon cycle?
• How many possible paths are there for a carbon
atom to move through the environment?
• What happens to the carbon atom as it moves from 1
pool to another? Give an example.
• Name some places where carbon appears to “get
stuck” in a pool and not move for some time. Why
might this be?
• Humans have a big influence on the carbon cycle.
What would the carbon cycle be like without
humans? What is our impact on the carbon cycle?
The carbon cycle
with and without humans
•
In 1750, WITHOUT industry &
vehicles, there was around 280 CO2
molecules in every million air
molecules
•
In 2007, WITH industry &
vehicles, there is now 380 CO2
molecules in every million air
molecules (35% increase)
