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

In this activity, learners measure the amount of carbon dioxide in a carbonated drink.

In this activity (on page 146 of the PDF), learners will explore the effects of increased carbon dioxide in the bloodstream.

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

In this activity (on page 142 of the PDF), learners will compare breathing rates before and after hyperventilation to explore how reduced carbon dioxide levels in the blood lower the need to breathe.

In this activity, learners conduct an experiment to find the volume of one mole of gas. Learners capture sublimated gas from dry ice in a ziploc bag and use water displacement to measure its volume.

In this activity, learners explore sublimation by conducting experiments with dry ice.

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.
