Teaching Tips

About the Science

  • Video makes its points quickly and effectively but lacks the nuance and detail that older audiences would require.
  • Video uses the atmosphere as a blanket analogy (e.g., it shows heat bouncing off the bottom of the atmosphere, suggesting that trapped heat is generated on Earth rather than solar radiation generating the heat and the atmosphere trapping it), which may lead to misconceptions. The instructor should plan to address these mis-representations/misconceptions.
  • Comments from expert scientist: clarity of language and good use of graphics. It is not precise to say that the Sun delivers light and heat. The Sun delivers radiation (short-wave) that is used by the Earth to warm. The Earth emits thermal radiation (long-wave) that is trapped in the atmosphere.

About the Pedagogy

  • Uses an engaging cartoon format. Short and to the point regarding what is causing the Greenhouse Effect. This is a simplified approach that is very suitable for middle school students.
  • No transcript or teacher's guide is available.

Technical Details/Ease of Use

  • The animation style of this video will not suffer if projected in a classroom.
