In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

Ocean acidification is a big issue due to the amount of carbon dioxide humans release. CO2 in the atmosphere is absorbed into the ocean thus changing its acidity.

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

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

In this activity, learners observe what happens when yeast cells are provided with a source of food (sugar). Red cabbage "juice" will serve as an indicator for the presence of carbon dioxide.

In this chemistry activity, learners use spaghetti to explore density and chemical reactions.

In this two-part activity, learners use everyday materials to visualize one mole of gas or 22.4 liters of gas. The first activity involves sublimating dry ice in large garbage bag.

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 activity, learners construct and launch rockets using simple materials and their understanding of chemical reactions.

In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

In this activity, learners sublimate dry ice and then taste the carbon dioxide gas.

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.

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 chemistry activity, learners use common chemicals to produce carbon dioxide and observe its properties. This resource includes brief questions for learners to answer after the experiment.

In this activity, learners observe as soap bubbles float on a cushion of carbon dioxide gas. Learners blow bubbles into an aquarium filled with a slab of dry ice.

This activity teaches combustion as the interaction of a fuel source and oxygen.

In this quick activity (page 1 of PDF under SciGirls Activity: Lift Off), learners will use the ever-popular soda geyser experiment to test the reactivity of the various sugar candies or mints.

In this chemistry activity, learners use common chemicals and metals to examine reactions that produce gaseous substances.

In this activity, learners find out what happens when they cover leaves with pieces of black construction paper. This activity shows learners that plants need sunlight to survive.

Learners mix vinegar and baking soda to produce a gas. With the addition of a bit of liquid soap, the gas becomes trapped in measurable bubbles.
