Materials:
_____ CO2 closure loop diagram for willow
_____
One dollar bill and 10 pennies
_____
16 bingo chips or markers
Directions:
Look at the "CO2 Closure Loop Cycle". The diagram shows
what happens to 100g of CO2 in the cycle of growing and using Willow
as a biomass fuel source. This diagram or model will be used to
explain the closed loop cycle for willow biomass.
Every
penny will equal 1 gram of CO2
What
ratio will be used in this model? 1 penny = _____________
$1.00
= 100 g of CO2
1)
On your diagram place the dollar bill to the left side. This represents
the starting point of 100 g of CO2 taken in by the plants to be
used for their growth.
2)
Place the number of pennies that equals the amount of CO2 released
to the atmosphere through the willow biomass production stage of
the cycle on the tree. How many did you place on the tree? ____________________
