This video focuses on the conifer forest in Alaska to explore the carbon cycle and how the forest responds to rising atmospheric carbon dioxide. Topics addressed in the video include wildfires, reflectivity, and the role of permafrost in the global carbon cycle.

This issue of the free online magazine, Beyond Penguins and Polar Bears, explores the Sun's role in warming Earth, the albedo (reflectivity) of Earth's diverse surfaces, and how the decline of Arctic sea ice is affecting Earth's energy balance. Science lessons introduce the concepts of solar energy, reflection, and absorption to elementary students. The issue also includes an overview of the natural resources and energy sources found in the polar regions as well as lessons that allow students to develop the concepts of natural resources, energy sources, and energy efficiency.

This article assembles free resources from the Energy and the Polar Environment issue of the Beyond Penguins and Polar Bears cyberzine into a unit outline based on the 5E learning cycle framework. Outlines are provided for Grades K-2 and 3-5.

An activity focusing on black carbon. This activity explores the impacts of the use of black carbon generating wood, dung, and charcoal for fuel in developing countries.

In this activity, students use authentic Arctic climate data to explore albedo and its relationship to seasonal snowmelt as a self-reinforcing feedback mechanism, which is then applied to large scale global climate change.

Student teams explore atmospheric aerosols, dust, and fires and their impact on the Earth's albedo using NASA Earth Observations (NEO) website. This is an extension activity in the student learning activity guide accompanying the GLOBE Earth System Poster, Exploring Connections in Year 2007. A series of six learning activities and associated assessment activities are included.

This video montage of spectacular NASA satellite images set to music shows different types of ice and ice features as well as descriptions of satellite-based measurements of ice cover. Text captioning describes how global ice cover is changing, and how this is measured.

The activity follows a progression that examines the CO2 content of various gases, explores the changes in the atmospheric levels of CO2 from 1958 to 2000 from the Mauna Loa Keeling curve, and the relationship between CO2 and temperature over the past 160,000 years. This provides a foundation for examining individuals' input of CO2 to the atmosphere and how to reduce it.

This article describes a researcher's history of studying sea ice and the dynamic nature of observed changes to the sea ice in the polar regions.

This article features science lesson plans to teach elementary students about the sun's energy, the relationship between light and heat, albedo, and the absorption of different surfaces. National standards and literacy integrations are provided for each lesson.

Students explore the greenhouse effect in this lesson using a computer simulation and develop a model for how it works.

This short video, is the fifth in the National Academies Climate Change, Lines of Evidence series. It focuses on greenhouse gases, climate forcing (natural and human-caused), and global energy balance.

Students observe demonstrations, and build and evaluate simple models to understand the greenhouse effect, the role of increased greenhouse gas concentration in global warming, and the implications of global warming theory for engineers, themselves and the Earth. In an associated literacy activity, students learn how a bill becomes law and research global warming legislation.

This is a classroom activity about the forcing mechanisms for the most recent cold period: the Little Ice Age (1350-1850). Students receive data about tree ring records, solar activity, and volcanic eruptions during this time period. By comparing and contrasting time intervals when tree growth was at a minimum, solar activity was low, and major volcanic eruptions occurred, they draw conclusions about possible natural causes of climate change and identify factors that may indicate climate change.

This video and accompanying essay review the impacts of rising surface air temperatures and thawing permafrost on ecosystems, geology, and native populations in Alaska.

This activity uses a mix of multimedia resources and hands-on activities to support a storyline of investigation into melting sea and land ice.

In this activity, students pose several hypotheses for what will happen if you continue heating or supplying energy to the hot and cold planet models (Mercury, Mars, Venus, and Earth) and then test their hypotheses using a spreadsheet based radiation balance model. The activity supports investigation of a real world challenge, experimenting with life support conditions for Mars at an Arctic outpost. The interactive model runs are conducted using a Java applet. This resource includes student worksheets, assessment questions and a teacher's guide. This is Activity B in module 2, Modeling hot and cold planets, of the resource, Earth Climate Course: What Determines a Planet's Climate? The course aims to help students to develop an understanding of our environment as a system of human and natural processes that result in changes that occur over various space and time scales.

This video contains a visualization and explanation of the Arctic sea ice and how it has changed over the 25 years. In September 2012, the National Snow and Ice Data Center recorded the lowest extent of Arctic sea ice. The video discusses the climate importance of ice thickness, reflective properties, and self-reinforcing feedback mechanisms.

How does energy flow in and out of our atmosphere? Explore how solar and infrared radiation enters and exits the atmosphere with an interactive model. Control the amounts of carbon dioxide and clouds present in the model and learn how these factors can influence global temperature. Record results using snapshots of the model in the virtual lab notebook where you can annotate your observations.

In this activity, students consider Greenland reflectivity changes from 2000 to 2012 and what albedo anomalies may indicate about how the Greenland ice sheet is changing in a case study format.
