f. The interconnectedness of Earth's systems means that a significant change in any one component of the climate system can influence the equilibrium of the entire Earth system. Positive feedback loops can amplify these effects and trigger abrupt changes in the climate system. These complex interactions may result in climate change that is more rapid and on a larger scale than projected by current climate models.

This set of animations and interactive simulations from the Byrd Polar Research Center at Ohio State University helps students develop an understanding of models used to understand the Earth system. Students consider the types of data that need to be included in a climate model, looking at inputs, outputs, and variables. The animations show how data is calculated for grid cells and assembled into a comprehensive model.

An interactive simulation that allows the user to adjust mountain snowfall and temperature to see the glacier grow and shrink in response.

An engaging and informational video describing the history of our knowledge about climate change.

Students observe the process of evaporation, make comparisons about the process, then construct a diagram and use it to describe the process of evaporation.

In this problem-based learning module, students research and report on Hurricane Katrina, using an earth systems science analysis approach.

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