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 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

In this activity, learners discover if carbon dioxide has an effect on temperature.

Using zebra mussels (Dreissena polymorpha), elodea and an indicator dye, learners study the role of light in photosynthesis.

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

In this activity (on page 1), learners role play as atoms to explore how atoms can be rearranged to make different materials.

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

In this activity, learners conduct an experiment to investigate the effect of elevated levels on CO2 on plant growth.
