Teaching Tips | Science | Pedagogy |
- 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.

Disciplinary Core Ideas: 4
HS-ESS1.B2:Cyclical changes in the shape of Earth’s orbit around the sun, together with changes in the tilt of the planet’s axis of rotation, both occurring over hundreds of thousands of years, have altered the intensity and distribution of sunlight falling on the earth. These phenomena cause a cycle of ice ages and other gradual climate changes.
HS-ESS2.A1:Earth’s systems, being dynamic and interacting, cause feedback effects that can increase or decrease the original changes.
HS-ESS2.A3:The geological record shows that changes to global and regional climate can be caused by interactions among changes in the sun’s energy output or Earth’s orbit, tectonic events, ocean circulation, volcanic activity, glaciers, vegetation, and human activities. These changes can occur on a variety of time scales from sudden (e.g., volcanic ash clouds) to intermediate (ice ages) to very long-term tectonic cycles.
HS-ESS2.D1:The foundation for Earth’s global climate systems is the electromagnetic radiation from the sun, as well as its reflection, absorption, storage, and redistribution among the atmosphere, ocean, and land systems, and this energy’s re-radiation into space.
