Teaching Tips

  • This may be a good video to introduce how satellite observations complement scientific research and supply valuable information to create a foundation for understanding global climate change. For younger audiences you may find additional online resources here http://climate.nasa.gov/kids/bigQuestions/oceanHappening/.
  • Recommend that educator narrate video and explain false coloration observed from satellite images of different wavelengths.

About the Science

  • As global ocean temperatures increase, the ocean water expands causing sea level rise, which can have disastrous impacts on low-lying coastal regions.
  • The video highlights the type of ocean data that the Modis and Jason satellites can collect, e.g. phytoplankton data and sea surface height.
  • The effect of a warming ocean on sea level rise with subsequent impact on coastal areas is also reviewed.
  • Comments from expert scientist: The site is visually very appealing with clear graphics illustrating the forcing factors (e.g. carbon dioxide concentrations) and consequences. The discussion follows a clear progression from things that are not in dispute to predictions which are less uncertain. Additional resources are particularly strong.

About the Pedagogy

  • Stunning images in high definition.
  • Understanding satellite images can be difficult and should be addressed, as color schemes can be in false colors.
  • Video could be used to help students make connections between certain images and the satellites used to create those images.

Technical Details/Ease of Use

  • Video composed of video clips and accompanying text for students to read. No narration.
  • Quality of video is high definition. It can be downloaded for ease of use.
