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 online reference list provides links to nine local and national environmental organizations that have Web sites rich in valuable biodiversity information. Where possible, it includes the following information for each: details about the organization's mission, knowledge base, and activities; the type of support offered, including educational materials, resource libraries, and classes/workshops; and mailing address and contact information. In addition, links to four Web directories are provided, which in turn have links to dozens of other organizations.

This article identifies age-appropriate national science education content standards and curriculum connections for introducing complex concepts contained in Principle 7 of the Essential Principles of Climate Sciences. The principle describes consequences of climate changes on Earth systems and human lives. The content standards will help teachers determine appropriate topics for their students. A number of resources from the online magazine Beyond Weather and the Water Cycle are highlighted for their connection to the science curriculum in the early grades. In addition, the article identifies common misconceptions about weather and the water cycle often held by students.

In the first video segment, we analyze the population dynamics for a test-tube of cells that affect each others' likelihoods of replication when they collide. The particular example we use is a prisoner's dilemma, which has the almost paradoxical property that survival of the relatively most fit leads overall fitness to decrease. In the second video segment, we suggest that the population dynamics from the first segment can be related to an analysis that uses payoff matrices found in traditional game theory.
