Notes From Our Reviewers The CLEAN collection is hand-picked and rigorously reviewed for scientific accuracy and classroom effectiveness. Read what our review team had to say about this resource below or learn more about how CLEAN reviews teaching materials
Teaching Tips | Science | Pedagogy | Technical Details

Teaching Tips

  • Use as a resource after teaching about the carbon cycle and greenhouse effect.
  • Run video through once, and then restart it to eliminate commercial for classroom use.
  • Educator may want to use accompanying visual examples of ocean acidification, ice albedo, and water vapor as a greenhouse gas.

About the Science

  • A British scientist, who has been involved with IPCC AR4, explains amplifying feedback. The primary focus is on how water vapor functions as a greenhouse gas, but he also cites other examples of climate feedbacks - ice albedo and ocean acidification.
  • Passed initial science review - expert science review pending.

About the Pedagogy

  • Good and accessible explanation of what a feedback mechanism is/does and the difference between positive and negative feedback.
  • This is strictly an interview with a scientist - no visuals to illustrate.

Technical Details/Ease of Use

  • Brief commercial at beginning of video.
