Students will explore time series plots and raw data to understand the role of sea surface temperature increases on arctic ice melt. This is part three of a four-part activity on polar science. The activity builds on the knowledge gained in Using... (View More)

In this learning activity, students compare changes in insolation with changes in surface temperature in the polar regions using scientific visualizations of global data sets. Links to readings related to the shrinking ice cap and albedo are... (View More)

In this learning activity, students compare polar data from the Arctic and Antarctic, explore Earth’s albedo and its effect on arctic sea ice, and examine graphed data and scientific visualizations of remotely-sensed satellite data. Readings... (View More)

This article describes an approach designed to decrease math anxiety and teach students about the use of mathematical symbols simplifying radicals. A deck of cards is used in a demonstration, and a problem set using real life examples to master the... (View More)

In this activity, students learn about the changing configuration of the continents over geological time resulting from plate tectonics. Using a map pair, students measure the difference in distance between continents 94 million years ago and today,... (View More)
