What question are we trying to answer in this lesson?
A. Why is there so much peat?
B. What produces oxygen?
C. How does temperature affect decomposition?
D. What is the history of halloween?
What did the banana peel help us remember about what happens to plants when they die?
A. When plants die, they magically disappear
B. When plants die, they decompose and nutrients are recycled
C. When plants die, they are converted into oxygen gas
What evidence did we collect from BANANA and YEAST systems that can help us understand how decomposition works in the peat/permafrost system
A. Decomposition occurs faster in
colder
temperatures
B. Decomposition occurs faster in
warmer
temperatures
C. Temperature does not affect the rate of decomposition
Where is the energy and matter in the peat/permafrost system?
trapped in the frozen ice
trapped in the peat
trapped in the soil
trapped in the rock

Why do zombie fires tend to occur more often when the Arctic experiences warmer than normal summers?
increased lighting strikes
thawing of permafrost
human interference
enhanced fire prevention measures
What significant environmental concern is associated with zombie fires?
rapid soil cooling
mass migration of animals
release of carbon dioxide into the atmosphere
decline in global temperatures
The hypothesis of this lab was decomposition happens faster in warmer conditions. Was the hypothesis supported?
yes
no
In warmer conditions, the yeast broke down more sugar and produced more
A. oxygen gas
B. carbon dioxide gas
Yeast is breaking down sugar by performing what process?
A. photosynthesis
B. mitosis
C. cellular respiration
D. DNA replication
How does this experiment relate to the peat/permafrost system?
A. The temperature in the Arctic is getting
warmer
so more peat is decomposing which is releasing more CO2 into the air.
B. The temperature in the Arctic is getting
colder
so more peat is decomposing which is releasing more CO2 into the air
C. The temperature in the Arctic does not change the rate at which peat is decomposing
