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

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

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

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 is a chemistry lab activity about solutions (page 7 of the PDF). Learners see firsthand how chemicals in a solution can combine to form an entirely different substance.

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

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

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

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.

Visitors observe a bottle with a balloon attached around the mouth. The bottle contains a solution of yeast, sugar, and water.

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.

Visitors mix water and sodium bicarbonate (baking soda) in a large flask. They then add citric acid to the mixture and stopper the flask. The resulting reaction creates carbon dioxide gas.

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 make a miniature greenhouse or "terrarium" to explore the greenhouse effect.
