Teaching Tips

  • Would best be used in conjunction with a diagram that explains the chemical reactions behind ocean acidification since the video does not provide information about the chemistry of ocean acidification.
  • Could be used to introduce a discussion of ocean acidification.
  • Educators may wish to use the longer version of the film, available at http://www.nrdc.org/oceans/acidification/aboutthefilm.asp

About the Science

  • Video links the change in ocean chemistry to impacts on coral reefs and fish populations and to other pressures on marine environments.
  • Citations for the longer version of this video are at http://www.nrdc.org/oceans/acidification/science.asp
  • While National Resources Defense Council (NRDC) is an advocacy group, the science in the video is correct, not exaggerated, and uncertainty stated appropriately.
  • Science Expert comment: Dissolving CO2 in water does not result in a pink cloud.
  • Comments from expert scientist: This video takes a complicated topic and simplifies it so that it should be generally understandable to most people. The animation of CO2 dissolving in the ocean is nice - I know that this is a concept students of mine have struggled with. The interviews with prominent and respected researchers adds to the merit of the video.
