This Flash-based simulation explores the relationship between carbon emissions and atmospheric carbon dioxide using two main displays: (1) graphs that show the level of human-generated CO2 emissions, CO2 removals, and the level of CO2 in the atmosphere, and (2) a bathtub animation that shows the same information as the graphs. The bathtub simulation illustrates the challenges of reducing greenhouse gas concentrations in the atmosphere.

Students analyze complex real-world problems by specifying qualitative and quantitative criteria and constraints for solutions that account for societal needs and wants. This place-based activity discusses multiple strategies to reduce carbon emissions, and realistic paths to preventing climate change.

This simulation allows the user to project CO2 sources and sinks by adjusting the points on a graph and then running the simulation to see projections for the impact on atmospheric CO2 and global temperatures.

This video succinctly explains the mechanism of the natural greenhouse effect and the cause of global climate change (anthropogenic global warming). It is short, basic, and to the point. It's also available in 12 languages!

This is a series of 10 short videos, hosted by the National Science Foundation, each featuring scientists, research, and green technologies. The overall goal of this series is to encourage people to ask questions and look beyond fossil fuels for innovative solutions to our ever-growing energy needs.

This straightforward calculator provides conversions from one unit of energy to the equivalent amount of CO2 emission expected from using that amount.

This game is an expansion on the popular board game Catan, it adapts the regular Catan game to become a game about sustainability and climate change. It's a neat idea, but teachers must already own the game and know how to play it.

This game-based learning would be great for after-school activities, environmental clubs, or a 'free' period in school. The amount of setup needed to get the game going and explain the rules may be too involved for regular classroom use.

This carbon calculator, developed by the EPA, guides students in calculating their carbon footprint and then using that information to make decisions about how to reduce their carbon emissions.

This video features the story of a multi-generational, family-run dairy business in Oregon. The family strives for sustainability in their operations by conserving energy and reducing greenhouse gases across many aspects of their business.

Comprehensive curriculum/unit to teach how food systems affect climate change. Strong use of real data is embedded throughout. Full lessons, mini-lessons, and short videos are presented.
