Teaching Tips

  • Teachers will need to consider if the students need more information than is provided in this simplified video.

About the Science

  • The animation showing the interaction between solar irradiance and greenhouse gases is not correct. When educators use this animation, they should explain how the actual situation is more complex.
  • The difference between contemporary and fossil fuel sources of carbon dioxide is due to differences in the carbon isotopes involved. This is a physical property and not a chemical one.
  • The link between carbon dioxide concentrations and temperature is not explained. The correlation is left to suggest causation.
  • Comments from expert scientist: The revised video presents a very relevant theme and that causes enormous confusion in the general public. In this sense, it is helpful and can be easily understood by the lay public.

About the Pedagogy

  • The animations are playful and direct; they are quite approachable for young audiences.

Technical Details/Ease of Use

  • Suitable for classroom projection. It can be viewed online or downloaded.
  • The video is on vimeo.com and this could this be a problem in some schools.
