Carbon Changing Costumes The goal of this lab is to have you model how carbon moves in nature After EACH station you need to add the appropriate arrows to your diagram in your lab notebook!

Station 1 This experiment shows that carbon in CO2 moves more rapidly to the atmosphere from _____ water than from ______ water This means that carbon dioxide is more soluble in ______ water than _______ water.

Station 1 This experiment shows that carbon in CO2 moves more rapidly to the atmosphere from _warm_ water than from __cold_ water This means that carbon dioxide is more soluble in _cold_ water than __warm__ water.

Station 1 4. How does solubility change with temperature? CO2 Solubility Temperature

Station 1 4. How does solubility change with temperature? CO2 Solubility Temperature

Station 2 In the natural world, this experiment represents the movement of carbon from ________ to ________.

Station 2 (add part in blue to packet) In the natural world, this experiment represents the movement of carbon from _soil__ to _rivers/water BY PERCOLATION! *this is what makes creeks and rivers dirtier in the spring (more water causes more soil to percolate)

2 by percolation

Station 3 In the natural world, this experiment represents the movement of carbon from ________ to ________.

Station 3 (add part in blue to packet) In the natural world, this experiment represents the movement of carbon from _rocks/land__ to _water by erosion (rock weathering) *even though there was CO2 in the gas, you are looking at what was happening in the water (step 5)

River or the Ocean (Water) Station 3 Rock Weathering: CaCO3 + H2O + CO2  Ca2+ + HCO31- Limestone (Rock) River or the Ocean (Water)

2 by percolation

2 by percolation 3 by erosion (rock weathering)

STATION #4 Basically, you would find that the NaHCO3 turned to NaOH plus something that disappeared. What else was made? Carbon Dioxide! This is what happens when magma melts rocks and then the volcano explodes.

Station 4 In the natural world, this experiment represents the movement of carbon from ________ to ________.

Station 4 In the natural world, this experiment represents the movement of carbon from _inside the Earth__ to _atmosphere__.

Station 5 In the natural world, this experiment represents the movement of carbon from ________ to ________.

Station 5 In the natural world, this experiment represents the movement of carbon from _ocean water__ to _seafloor__.

Station 5 Making Limestone: Ocean Water Seafloor Ca2+ + 2Cl1- + 2HCO31- + 2Na1+  2Na1+ + 2Cl1- +CaCO3 + H2O + CO2 Ocean Water Seafloor

Station 7 In the natural world, this experiment represents the movement of carbon from ________ to ________.

Station 7 (add part in blue to packet) In the natural world, this experiment represents the movement of carbon from _soil__ to _atmosphere by microbial respiration

Station 7 Microbial Respiration: C6H12O6 2C2H5OH + 2CO2 + energy C6H12O6 3CH4 + 3CO2 + energy Soil Atmosphere Animals Atmosphere

HOMEWORK! Carbon Cycle diagram: I want you to transfer the diagram of your carbon cycle to a piece of paper to be turned in on Thursday. Make it pretty! The nice ones will be displayed in the classroom Your quiz on Thursday will be asking you to describe the path that a carbon atom could take. The more you work beforehand to understand where carbon goes and how it gets there, the easier the quiz will be.

MISCONCEPTIONS! Answer in notebook (you will be sharing these shortly so you need to not be a lazy-bones) Where do plants get the carbon to make sugar (glucose)? How do animals (like humans) get their Carbon? What are the options for CO2 in the ocean to do? Do fish absorb carbon from their environment? Does CO2 evaporate, condense, and precipitate?

Find your twin! When I say, find someone that shares a certain trait with you. When you find them, discuss the answer for the question we’re on and if they contribute a different idea, jot it down quickly. So you’ll need notebook and writing utensil

Where do plants get the carbon to make sugar (glucose)? Atmosphere (CO2) - NOT from soil Chemical process of Photosynthesis The soil provides other things like nitrogen, phosphorus, and potassium.

How do animals (like humans) get their Carbon? Food-not just by magical absorption

What are the options for CO2 in the ocean to do? React with water to make carbonic acid Taken in by an ocean plant Outgassing/exosolution (eventually)

Do fish absorb carbon from their environment? NO they eat food just like all animals to get their carbon. Stuff in the ocean works just like on land, plants take in CO2 and put out O2, Animals use O2 and eat to get Carbon and put out CO2

Does CO2 evaporate, condense, and precipitate? NO: but it can combine with water droplets What happens when CO2 goes into a water droplet?
