Global Warming: It's All About Carbon

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
  Can be used with multiple age groups to introduce or reinforce understanding of the properties of carbon as the key to global warming.
• About the Science
  Science concerns properties of carbon and why it is the key element in understanding and dealing with global warning. Video does take some poetic license with some science concepts. For example, it may perpetuate the misconception that the greenhouse effect is caused only by human activities linked to increased CO2. Comments from expert scientist: The scientific strengths are generally excellent because the message relies on well-established scientific understanding. The description of the greenhouse effect is not accurate. Greenhouse effect is a result of CO2 absorbing infrared radiation (heat), not reflected solar radiation, from the earth surface.
• About the Pedagogy
  Animations are appealing to a broad age range but mainly targeted toward middle school audience.
• Technical Details/Ease of Use
  Five videos of about 3-5 min length each.
