This lesson is a lab in which students use thermometers, white and dark paper, and lamps to measure differences in albedo between the light and dark materials. Connections are made to albedo in Antarctica.

This is a short experiment to demonstrate the concept of thermal expansion of water when heated, as an analogy to thermal expansion of oceans due to global warming.

In this video segment, adapted from a student video produced at Northwest Indian College in Bellingham Washington, Native American elders discuss the impact of climate change on salmon populations and the importance of restoring balance in the natural world.

This short video from NASA discusses the role that salinity plays in Earth's climate and ocean circulation, focusing on the observations of the Aquarius satellite.

This video segment is adapted from Building Big, a PBS series hosted by David Macaulay. It explores Hoover Dam's hydroelectric capabilities by explaining how it is able to harness the potential energy stored in the reservoir and convert it to electricity. It also discusses environmental impacts of the dam and others like it.

This video provides an overview of changes happening in the Arctic.

This is a teaching activity in which students learn about the connection between CO2 emissionS, CO2 concentration, and average global temperatures. Through a simple online model, students learn about the relationship between these and learn about climate modeling while predicting temperature change over the 21st century.

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.

This activity engages students in learning about ways to become energy efficient consumers. Students examine how different countries and regions around the world use energy over time, as reflected in night light levels. They then track their own energy use, identify ways to reduce their individual energy consumption, and explore how community choices impact the carbon footprint.

This video is from the Energy 101 video series. It explains the process for converting micro-algae into fuel and makes the case that algae-based biofuels hold enormous potential for helping reduce our dependence on imported oil.
