The activity follows a progression that examines the CO2 content of various gases, explores the changes in the atmospheric levels of CO2 from 1958 to 2000 from the Mauna Loa Keeling curve, and the relationship between CO2 and temperature over the past 160,000 years. This provides a foundation for examining individuals' input of CO2 to the atmosphere and how to reduce it.

Students conduct an energy audit to determine how much carbon dioxide their family is releasing into the atmosphere and then make recommendations for minimizing their family's carbon footprint. Students are specifically asked to understand the units of power and energy to determine the cost of running various household appliances. Finding the amount of carbon dioxide emitted for different types of energy and determining ways of reducing carbon dioxide output is the outcome of the lesson.

In this activity, student teams research and develop a proposal to decrease the carbon footprint of their city's/town's public transportation system and then prepare a report that explains why their transportation plan is the best for their community.

This board game, designed for middle school students, introduces the concepts of energy use in our lives and the real impact that personal choices can have on our energy consumption, energy bills, and fuel supply.

This is a laboratory activity in which students will compare the amount of carbon dioxide in four different sources of gas and determine the carbon dioxide contribution from automobiles. They test ambient air, human exhalation, automobile exhaust, and nearly pure carbon dioxide from a vinegar/baking soda mixture.

Students calculate the cost of the energy used to operate a common three-bulb light fixture. They then compare the costs and amount of CO2 produced for similar incandescent and compact fluorescent light bulbs. Students also do a short laboratory activity to visualize why two bulbs, which give off the same amount of light, use different amounts of electrical energy.

In this classroom activity, students measure the energy use of various appliances and electronics and calculate how much carbon dioxide (CO2) is released to produce that energy.

This is a team-based activity that teaches students about the scale of the greenhouse gas problem and the technologies that already exist which can dramatically reduce carbon emissions. Students select carbon-cutting strategies to construct a carbon mitigation profile, filling in the wedges of a climate stabilization triangle.

This video is one of a series produced by the Switch Energy project. It reviews the pros and cons of natural gas as a source of energy.

This video highlights the benefits of electric vehicles, including improved fuel efficiency, reduced emissions, and lower maintenance costs.
