Scientific data are often represented by assigning ranges of numbers to specific colors. The colors are then used to make false color images which allow us to see patterns more easily. Students will make a false-color image using a set of numbers.

The Eyjabakkajökull Glacier is an outlet glacier of the Vatnajökull ice cap in Iceland that has been retreating since a major surge occurred in 1973. Students analyze these maps to identify the scale, rate of change, and volume affected by the glacier retreat.
Information from satellites if often used to display information about objects. This information can include how things appear, as well as their contents. Explore how pixel data sequences can be used to create an image and interpret it.
Arctic sea ice is the cap of frozen seawater blanketing most of the Arctic Ocean and neighboring seas in wintertime. It follows seasonal patterns of thickening and melting. See how the quantity has changed from 1979 through 2018.
Students analyze four data visualizations focused on the topic of sea level. They use a jigsaw method to explore and communicate their findings with their peers.
Students will explore albedo, sea ice and the relationship between changing albedo and changing sea ice.
Students will use the NASA Earth Observations analysis tool to explore changing albedo in the Arctic compared with other areas of Earth.
Students will make a claim about whether changing albedo contributes to changes in Arctic habitats.
This lesson connects day/night and seasonal cycles with albedo in the Arctic region. Students will explore seasonal changes of albedo.
Introduction to the concept of albedo.
