Teaching Tips

  • This visualization was created as part of "Lesson 2" in a climate change module that can be seen at http://www.explainingclimatechange.ca/Climate%20Change/Lessons/Lesson%202/lesson2.html and also in the CLEAN collection.
  • Could be used as an introduction to how we know how global temperatures have changed over time to set up a comparison to how global temperatures have changed in recent years.
  • Teachers will have to provide questions students have to explore when reading through the webpages.

About the Science

  • Excellent step-by-step explanation of how ice core samples are used to determine historic temperature trends, including a breakdown of the biochemical processes that drive the process, the chemical equations and calculations used, and how the sampling process works in practice.

About the Pedagogy

  • The explanations are clear and straightforward and do an excellent job of communicating a complex process in simple terms.
  • Animation includes 5 nicely-designed webpages with a good explanation of the oxygen isotope dating method.

Technical Details/Ease of Use

  • The animations and text are displayed very clearly. Can only be viewed online (need internet access).
  • Well-designed pages with little ability to interact with the content.
