Teaching Tips | Science | Pedagogy |
- Visualization can be used to introduce the value of long-term data sets.
- If educator prefers to have students take data and draw the graph themselves, see http://nsidc.org/data/seaice_index/archives/image_select.html.
- Educator can show students the visualization of the sea ice first, and then engage class to hypothesize whether it is increasing or decreasing. Graph can be shown on a separate overlay and students can hypothesize how the change is affecting the ecosystem.
- It may be helpful to narrow students in on a particular location on the visualization - to help them see the differences over time.
About the Science
- The continued significant reduction in the extent of the summer sea ice cover is a dramatic illustration of the pronounced impact increased global temperatures are having on the Arctic regions. There has also been a significant reduction in the relative amount of older, thicker ice. Satellite-based passive microwave images of the sea ice cover have provided a reliable tool for continuously monitoring changes in the extent of the Arctic ice cover since 1979. The ice parameters derived from satellite ice concentration data that are most relevant to climate change studies are sea ice extent and ice area.
- This visualization shows ice extent in the background and ice area in the foreground.
About the Pedagogy
- Animation can be downloaded in a variety of forms allowing an educator to infuse this into a lesson on Arctic climate changes.
- The video could be used in a class presentation or images can be presented on a worksheet.
- Students should have an understanding of concepts of area vs. volume and concentration, what sea ice is and its importance.
Technical Details/Ease of Use
- Easy to use.
- A number of different sizes and file formats are available for download. However, some of the files are large and take a long time to download, so the educator should download prior to the class. Simple and complex animation files are available and the variety of image types makes this a very customizable tool.
- Difficult to see difference in color coding; might be useful to watch multiple times to better visualize and differentiate.

Disciplinary Core Ideas: 3
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.
HS-ESS2.E1:The many dynamic and delicate feedbacks between the biosphere and other Earth systems cause a continual co-evolution of Earth’s surface and the life that exists on it.
HS-ESS2.D4:Current models predict that, although future regional climate changes will be complex and varied, average global temperatures will continue to rise. The outcomes predicted by global climate models strongly depend on the amounts of human-generated greenhouse gases added to the atmosphere each year and by the ways in which these gases are absorbed by the ocean and biosphere.
Cross Cutting Concepts: 4
HS-C1.5:Empirical evidence is needed to identify patterns.
HS-C2.1:Empirical evidence is required to differentiate between cause and correlation and make claims about specific causes and effects.
HS-C7.2:Change and rates of change can be quantified and modeled over very short or very long periods of time. Some system changes are irreversible.
HS-C7.3:Feedback (negative or positive) can stabilize or destabilize a system.
Science and Engineering Practices: 1
HS-P4.2:Apply concepts of statistics and probability (including determining function fits to data, slope, intercept, and correlation coefficient for linear fits) to scientific and engineering questions and problems, using digital tools when feasible.
