Teaching Tips

Educators should examine the site in advance and look at different ranges of data.

Instead of just watching the animation, have students take data over a one-year period and also over a 20 year time interval. Then, have students construct graphs of their data and have a class discussion about their results.

Integrating a tool like this into a curriculum is a great way to get students involved in long-term data sets as they interact with the tool to observe changes.

Use this tool along with the resource "Graphing the Extent of Sea Ice in the Arctic and Antarctic" from Windows to the Universe [link], for "Compare Images of Arctic Sea Ice Extent Side-by-Side" [link] and "Compare Images of Antarctic Sea Ice Extent Side-by-Side" [link
