Arctic warming produces biological winners (whales) and losers (polar bears). This article explains why they are impacted differently and includes supplemental images. This lesson is part of the Climate Kids website, a NASA education resource... (View More) featuring articles, videos, images and games focused on the science of climate change. (View Less)
The movement of Arctic air, known as the Arctic oscillation, can and will cause periodic extreme winter weather outside the Arctic region - the harsh winter experienced in many parts of the U.S. in 2010 is a recent example. This article explains the... (View More) connection between the two events.

In this lesson students investigate the effects of black carbon on arctic warming and are introduced to a mechanism of arctic warming that is not directly dependent on greenhouse gases in the atmosphere: black carbon deposition on Arctic snow and... (View More) ice. It can also be used to introduce the concept of albedo. Prerequisite knowledge: students understand the concepts of absorption and reflection of light energy. This lesson is designed to be used with either an Earth/environmental science or chemistry curriculum. It may also be used as an enrichment activity in physics or physical science during a unit on energy. Includes suggested modifications for students with special needs and low technology option. Requires advance preparation, including freezing ice samples overnight. (View Less)
Through an analysis of data sets on four parameters - sea ice totals, sea surface temperatures, near surface temperatures and surface type - students must decide whether the Arctic is experiencing climate change and predict any potential effects on... (View More) the rest of the planet. The activity in this lesson involves card sorting, a technique in which index cards, each containing content or diagrams, are grouped according to unifying concepts. The cards in this lesson contain graphs that students have downloaded, summaries they have written, and questions they have derived from the lesson. The graphs used in this activity show satellite data sets for a location above the Arctic Circle. Students will analyze and group the cards and will then write a conclusion in which they explain the connection between the four parameters, and relate them back to climate change. This lesson uses student- and citizen science-friendly microsets of authentic NASA Earth system science data from the MY NASA DATA project. It also includes related links, extensions, an online glossary, and a list of related AP Environmental Science topics. (View Less)
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) related to the shrinking ice cap and albedo are linked to this lesson. This is part two of a four-part activity on polar science. Extension activities examining air and sea surface temperature in relation to changing Earth albedo are included. Data access information is provided in the attached appendix. This activity is one of several learning activities connected with the 2007 GLOBE Earth system poster. GLOBE (Global Learning and Observation to Benefit the Environment) is a worldwide, hands-on, K-12 school-based science education program. (View Less)
This set of three videos illustrates how math is used in satellite data analysis. NASA climate scientist Claire Parkinson explains how the Arctic and Antarctic sea ice covers are measured from satellite data and how math is used to determine trends... (View More) in the data. In the first video, she leads viewers from satellite data collection through obtaining a time series of monthly Arctic and Antarctic average sea ice extents for November 1978-December 2016. In the second video, she begins with the time series from the first video, removes the seasonal cycle by calculating yearly averages, and proceeds to calculate the slopes of the lines to get trends in the data, revealing decreasing sea ice coverage in the Arctic and increasing sea ice coverage in the Antarctic. In the third video, she uses a more advanced technique to remove the seasonal cycle and shows that the trends are close to the same, whichever method is used. She emphasizes the power of math and that the techniques shown for satellite sea ice data can also be applied to a wide range of data sets. Note: See Related & Supplemental Resources for the maps and data files (1978-2016) that will allow you to do the calculations shown in the video. These also include data for different regions of the Arctic and Antarctic, enabling learners to do additional calculations beyond those shown in the videos. (View Less)
One of Earth's vital signs, the extent of sea ice cover in the Arctic, is examined. An image and accompanying text describe the extent and consequences of the reduction in that sea ice.

Users explore data, using My World GIS, that characterize the dynamic Greenland Ice Sheet. By examining photographs, map views, and tabular data, users gain an understanding of how and why scientists are monitoring the ice sheet and what they are... (View More) finding. Users explore map layers that represent ice sheet thickness, weather station locations, and annual melt extents of the ice sheet. They learn about the working conditions that Arctic scientists must endure to collect their data, and how sensors on satellites are used to gather information from an area as large as Greenland. Finally, users learn about scientists' methods for measuring ice flowing downhill from Greenland, and examine that data to learn how fast the ice is moving. This chapter is part of the Earth Exploration Toolbook, which provides teachers and/or students with direct practice for using scientific tools to analyze Earth science data. Students should begin on the Case Study page. (View Less)
This investigation compares changes in ozone above the Arctic and the Antarctic. Students use text, tables, diagrams, images and photos to investigate the human-caused effects, the populations most at risk, and the different international... (View More) perspectives on solutions. To emphasize the effectual differences between the Arctic and Antarctic, groups of students argue positions at a "mock" meeting of a Montreal Protocol committee. The URL opens to the investigation directory, with links to teacher and student materials, lesson extensions, resources, teaching tips, and assessment strategies. This is Investigation 2 of three found in the Grades 9-12 Module 3 of Mission Geography. The Mission Geography curriculum integrates data and images from NASA missions with the National Geography Standards. Each of the three investigations in Module 3, while related, can be done independently. (View Less)
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) Data and Images to Understand Albedo (part 2). Extension activities examining air and sea surface temperature in relation to changing Earth albedo are included. Information is provided on data access using the NOAA Earth System Research Laboratory Web site. This activity is one of several learning activities connected with the 2007 GLOBE Earth system poster.
