Energy and the Polar Environment

In this issue's Science and Literacy department, we discuss 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. In our Across the Curriculum department, we focus on another common concept: natural resources. We provide an overview of the natural resources and energy sources found in the polar regions. Lessons allow students to develop the concepts of natural resources, energy sources, and energy efficiency.
