How Carbon Affects Nearly Everything on Earth – Including Our Future

|
Ask a Question

Synopsis
  • This illustrated video describes the carbon cycle, demonstrating how climate change affects everything and everyone due to carbon's ubiquity on Earth.
  • The video features excellent visuals showing carbon atoms pumping through the atmosphere into living organisms and the ocean in a cycle of carbon sources and sinks.
  • Next, the video highlights the imbalance in the carbon cycle caused by humans burning fossil fuels and by farming and deforestation.
Teaching Tips

Positives

  • This video uses observed data on a graph to show evidence of a changing climate due to excess greenhouse gases from human activities.
  • By showing carbon in different locations at the molecular level (represented by a C in a bubble), students gain an introduction to a bit of the chemistry of climate change.
  • This is a great introductory video about the carbon cycle for many age groups.

Additional Prerequisites

  • Students should know that the element carbon is represented by the letter C.
  • Students should be familiar with different types of fossil fuels and their use.

Differentiation

  • Younger learners may benefit from stopping the video periodically to check for understanding, as well as slowing the video playback speed to allow adequate time to read the text and view the animations.
  • Before watching the video, ask students if they know of different places that carbon is stored on Earth.
  • A graphic organizer may be helpful for students to take notes on different processes in the carbon cycle, such as photosynthesis, decomposition, erosion, ocean acidification, and volcanism.
  • Consider having students investigate alternative energy sources and discuss if they impact the carbon cycle.
Scientist Notes
This video resource from the Smithsonian’s National Museum of Natural History uses clever animation to describe the carbon cycle. The natural climate cycle, as it has operated for tens of millions of years, connects plants, soil, oceans, and volcanoes to the atmosphere, which is depicted as a large gas tank. The whole tone of the video changes with the industrial revolution as fossil fuels begin to be mined and burned, deforestation and farming increase, and atmospheric carbon grows by 42% over the last 150 years. A warming climate and ocean acidification are listed as results of the growth in atmospheric carbon, and the video closes with a call to action to reduce carbon emissions to improve our quality of life. This video very clearly illustrates the carbon cycle and how human activity has thrown it out of whack. This resource is recommended for teaching.
