Evidence That Carbon Dioxide Traps Heat | Decoding the Weather Machine

Notes from our reviewers

• Teaching Tips
  This is an interesting video that clearly presents the facts that the greenhouse effect was studied and understood close to 200 years ago. It could be a valuable piece of a larger lesson on the history of climate science. It does omit one figure deserving of recognition, Eunice Foote. This is a missed opportunity, though it doesn't detract from the elegance of Tyndall's experiment.
• About the Science
  This video explains John Tyndall's experiment that revealed evidence that carbon dioxide traps heat. Tyndall is given credit and deserves accolades, but history should at least acknowledge that Eunice Foote's similar research was presented to AAAS by Joseph Henry four years prior. Consequently, teachers may want to review some of the history of science with students before or after this video. Passed initial science review - expert science review pending.
• About the Pedagogy
  In the supplementary materials, there is a teaching tip page that has questions for engagement during the video, encouraging science practices, and discussion questions for after the video. These are thought-provoking questions that will extend students' thinking past the experiment and to the present day.
• Technical Details/Ease of Use
  Video length is 4:17 minutes.
