In this activity, learners investigate carbon sequestration by creating a carbonated beverage out of apple juice and dry ice.

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

In this geology activity (page 6 of the PDF), learners explore how carbonic acid can slowly dissolve limestone and form caves.

This is an activity about acid-base reactions using eggs and vinegar. Learners place eggs inside a container of vinegar and leave to soak overnight.

In this chemistry activity (page 8 of the PDF), learners will identify the instances of physical change, chemical change, and solutions while making homemade soda pop.

In this life science activity (page 8 of the PDF), learners explore the carbon cycle by mixing yeast, sugar and water.

Learners discover the bubble power of living cells in this multi-hour experiment with baker's yeast. Learners make a living yeast/water solution in a bottle, and add table sugar to feed the yeast.

Does yeast breathe? Find out by watching how plastic bags filled with yeast, warm water and different amounts of sugar change over time.

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

In this activity, learners heat and cool carbonated water to find out whether temperature has an effect on how fast the dissolved gas leaves carbonated water.

In this chemistry meets cooking activity, learners make carbonated, vanilla ice cream using dry ice and denatured ethanol, which are both inexpensive and accessible.

In this activity, learners add objects and substances to carbonated water to discover that added objects increase the rate at which dissolved gas comes out of solution.

In this activity, learners make a yeast-air balloon to get a better idea of what yeast can do. Learners discover that the purpose of leaveners like yeast is to produce the gas that makes bread rise.

In this activity, learners will discover why there are holes in bread.

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.

This hands-on activity lets participant explore chemical reactions as they create a soda explosion with lots of bubbles. The bubbles in soda are made of carbon dioxide gas.

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

In this activity, learners use gumdrops and toothpicks to model the composition and molecular structure of three greenhouse gases: carbon dioxide (CO2), water vapor (H2O) and methane (CH4).

In this activity, learners conduct a controlled experiment to examine which brand of soda makes the best (highest) soda geyser.

In this activity about combustion and energy, learners observe a burning candle in a sealed jar and the burning of white sugar.
