Positives

• Students will be able to visualize the number of carbon dioxide atoms in one liter and therefore better understand the rapid rate of warming occurring on Earth.
• The video uses a simple illustration to review the concept of the greenhouse effect.

Additional Prerequisites

• The host speaks quickly, so teachers may want to pause periodically to check for understanding.
• The video is designed for students with high-level math skills.
• Students should be familiar with moles, Avogadro's number, and standard temperature and pressure.

Differentiation

• Math or earth science classes could look up the present carbon dioxide levels and use that to calculate the number of carbon dioxide molecules in a liter of air at this moment. Students could compare the present number with the number from when the video was produced in 2020.
• Teachers could challenge students to use the equations from this video to calculate the concentrations of other greenhouse gases like methane, nitrous oxide, or water vapor.
• Chemistry classes could find out more about Avogadro's number and how it allows scientists to make important measurements and calculations.
• Other resources on this topic include this interactive graph that shows the change in atmospheric carbon dioxide levels, this video that explains how humans disrupted the carbon cycle, and this video on the potential for mass carbon capture.
