1. Station #1– CO2 Solubility
Carbon Forms:
Exsolution: CO2 (aq) CO2(g)
Dissolution: CO2(g) CO2 (aq)
Substances with HIGH solubility tend to stay in the liquid
CO2 is MORE soluble in COLD water when compared to WARMER water
Shows carbon in the form of CO2 moves more rapidly to hot water than from cold water. Carbon dioxide is more soluble in cold water than hot water.
BIG ideas for each station – Have copy on station notes IF no room okay on back

2. Station #2 – Soil Leaching
Soil is a mixture of random plants and animals in various stages of decay
DOC is the main form of carbon– okay if you stated, dirt, soil or glucose
Carbon from soil (land, terrestrial environments) to rivers or lakes (water)

3. Station #4 – Limestone Metamorphism
Represents Carbon moving from inside the earth to the atmosphere
Limestone that has undergone metamorphosis = Marble
CO2 and CaCO3 are the major forms of carbon represented at this station

4. Station #5 – Making Limestone
CaCO3 sinks to the bottom of the beaker – deeper water
2NaHCO Na + 2HCO3
CaCl Ca + 2Cl
Carbon ENDED in the form of CaCO3 and CO2
CaCl2 was more alkaline (base) compared to the NaHCO3
Mixing the 2 made a stronger acid -- Precipitate of “limestone” at the bottom of beaker
Carbon moving from the ocean water to the seafloor.

5. Station #6 -- Photosynthesis
Carbon Forms:
CO2, C6H12O6
6H2O + 6CO2 + energy C6H12O O2
Carbon moving from atmosphere (air) to vegetation (plants).

6. Station #7 – Microbial Respiration
Carbon Forms:
C6H12O6, CO2 , C2H5OH, CH4
C6H12O CO CH4
Demonstrating that Carbon decaying in soil can release as more that just CO2.
Carbon movement from soils to atmosphere.

7. Station #8 – Respiration Station
Carbon Forms:
C6H12O6, CO2
C6H12O6 + 6O H2O + 6CO2 + energy
Carbon movement from food to the atmosphere.
