This activity utilizes a PhET greenhouse gas simulation to explore the interaction of different atmospheric gases with different types of radiation.

This three-part, hands-on investigation explores how sunlight's angle of incidence at Earth's surface impacts the amount of solar radiation received in a given area. The activity is supported by PowerPoint slides and background information.

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.

An interactive that illustrates the relationships between the axial tilt of the Earth, latitude, and temperature. Several data sets (including temperature, Sun-Earth distance, daylight hours) can be generated.

This lesson covers different aspects of the major greenhouse gases - water vapor, carbon dioxide, methane, nitrous oxides and CFCs - including some of the ways in which human activities are affecting the atmospheric concentrations of these key greenhouse gases. This is lesson six in a nine-lesson module about climate change.

This interactive animation focuses on the carbon cycle and includes embedded videos and captioned images to provide greater clarification and detail of the cycle than would be available by a single static visual alone.

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.

This interactive graphic outlines the carbon cycle, with clickable text boxes that explain and elaborate each component.

This NASA video discusses the impacts of the sun's energy, Earth's reflectance, and greenhouse gases on the Earth System.

Two simple experiments/demonstrations show the role of plants in mitigating the acidification caused when CO2 is dissolved in water.
