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

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

Learners explore the relationship between energy consumption, population, and carbon emissions in the countries of the Americas.

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 will plot the distribution of various oozes using information from sediment maps.

In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.

In this lesson, learners will practice graphing and statistically analyzing data.
