CARBON SOURCES - Climate Change Videos
With Lesson Plans and Links
Episode 1 - Carbon Dioxide Is a Greenhouse Gas [8:32]
​
This visual dictionary explains the basic vocabulary words viewers need to understand the video series. It's a good way to make sure everyone is on the same page, including definitions of greenhouse gases, weather vs climate, etc.

​
Episode 2 - Carbon from Gas Exchange (Cellular Respiration) [8:43]
​
We exhale 100 x more CO2 than we inhale. That doesn't create climate change but discovering the source of that carbon gives us insight into the carbon cycle and burning questions like, "Where does fat go when we lose it?" and "What are carbs anyway?"

Episode 3 - Carbon from Campfires [7:06]
​
Wood fires produce carbon dioxide because cellulose (and other big molecules that make up wood) are carbon based. Those molecules can produce carbon dioxide in three different ways: digestion, decomposition, and combustion.

Episode 4 - Carbon from Coal-Fired Power Plants [8:07]
​
After a quick look at coal formation and a zip through the Industrial Revolution, viewers learn how burning coal can generate electricity that lights up the night. I make a very simple DIY generator.

Episode 5 - Carbon from Crude Oil Fuels [9:01]
​
Crude oil started out as plankton in ancient oceans. After refining it, we use the gasoline to fuel our cars, ships, and airplanes. Thanks to Joe Kaufman for a great model of how internal combustion engines work in his book, What Makes It Go?

​
Episode 6 - Carbon from Natural Gas (Methane) [10:14]
​
Natural gas is mostly made of methane, CH4. I discuss fracking to collect natural gas from shale. We burn gas for heat in homes, industry and electricity generation. Methane in our atmosphere is a powerful greenhouse gas that we must control.

Episode 7 - Carbon from Volcanoes [8:37]
​
Volcanoes can change the weather, globally and for several years. But how much carbon dioxide do they emit compared to our anthropogenic (man-made) carbon dioxide output?

Carbon Sinks - Photosynthesis and Trees (9:38)
​
@STEMwithCog explores where trees get their mass and why we say it comes from thin air. Cog explores photosynthesis and how makes sugars for the cell. Those sugars are used as an energy source or broken down with oxygen to make the tree

CARBON SINKS VIDEOS (where carbon is stored)
with Lesson Plans and Links
​
@STEMwithCog explores oceans, how they absorb excess carbon and move it up the marine food pyramid until it decomposes or is buried. Limiting factors like iron control populations. Watch demos of CO2 absorption and heat absorption. Learn about ocean currents, weather, and climate.

Carbon Sinks - The Slow Carbon Cycle (9:45)
​
@STEMwithCog explores how some marine organisms can extract calcium and carbonate from ocean water, forming calcium carbonate shells. These shells can become rock that is chemically weathered to release CO2, which can be absorbed by oceans, starting the cycle again.
