This interactive visualization adapted from NASA and the U.S. Geological Survey illustrates the concept of albedo, which is the measure of how much solar radiation is reflected from Earth's surface.

This 15-panel interactive from NOVA Online describes some of the factors (such as Earth's rotation and the sun's uneven heating of Earth's surface) contributing to the formation of the high-speed eastward flows of the jet streams, found near the top of the troposphere. These jet streams play a major role in guiding weather systems.

This introductory video summarizes the process of generating solar electricity from photovoltaic and concentrating (thermal) solar power technologies.

This is an animated interactive simulation that illustrates differential solar heating on a surface in full sunlight versus in the shade.

This animation demonstrates the changing declination of the sun with a time-lapse animation. It shows how the shadow of a building changes over the course of a year as the declination of the sun changes.

This video provides a good overview of ice-albedo feedback. Albedo-Climate feedback is a positive feedback that builds student understanding of climate change.

This short video, adapted from NOVA, explains how Earth's position relative to the Sun might be responsible for the dramatic shift in the climate of what is now the Saharan nation of Djibouti.

In this video, students learn that scientific evidence strongly suggests that different regions on Earth do not respond equally to increased temperatures. Ice-covered regions appear to be particularly sensitive to even small changes in global temperature. This video segment adapted from NASA's Goddard Space Flight Center details how global warming may already be responsible for a significant reduction in glacial ice, which may in turn have significant consequences for the planet.

This video segment, from the 'Earth: The Operators' Manual' featuring climate expert Richard Alley, shows how ice cores stored at the National Ice Core Lab provide evidence that ancient ice contains records of Earth's past climate - specifically carbon dioxide and temperature.

This video introduces the concept of daylighting - the use of windows or skylights for natural lighting and temperature regulation - and how it is a building strategy that can save operating costs for homeowners and businesses.
