In this inquiry-based lesson, learners measure the biomass of trees, calculate the carbon stored by the trees, and use this information to create recommendations about using trees for carbon sequestra

Through discussion and hands-on experimentation, learners examine the geological (ancient) carbon cycle.

This game introduces learners to the scale of the greenhouse gas problem, plus technologies that already exist to dramatically reduce our carbon emissions and prevent climate change.

In this activity about global climate change, learners will conduct an experiment and collect data to compare the amount of carbon dioxide (CO2) in four different sources of gases.

In this lesson plan, learners examine some of the of greenhouse gas emissions sources in their community.

Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.

In this activity, learners investigate various appliances and electronics, discovering how much energy each uses and how much carbon dioxide (CO2) is released to produce that energy.

In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.
