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.

Learners blow into balloons and collect their breath--carbon dioxide gas (CO2). They then blow the CO2 from the balloon into a solution of acid-base indicator.

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

In this demonstration, learners observe vinegar and baking soda reacting to form carbon dioxide (CO2) gas.

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.

Learners test two jars, one containing plain air and one containing carbon dioxide gas, to see their reactions to temperature changes.

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 is a chemistry lab activity about solutions (page 6 of the PDF). Students make a limewater testing solution for carbon dioxide and explore the concepts of solubility and precipitates.

Learners make a mobile model of a carbon atom using clay, wire, and pipe cleaners.

In this activity (on page 8), learners model how marble statues and buildings are affected by acid rain.

In this activity (page 26 of the PDF), learners make observations, formulate hypotheses and design a controlled experiment, based on the reaction of carbon dioxide with calcium hydroxide.

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.

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

In this activity, learners make film canister rocket ships. A fin pattern is glued onto the outside of the canister, and fuel (water and half an antacid tablet) is mixed inside the canister.

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 simple activity, learners see the production of a gas, which visibly fills up a balloon placed over the neck of a bottle.

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

In this demonstration, learners compare and contrast regular water ice to dry ice (frozen carbon dioxide). Both samples are placed in a solution of acid-base indicator.

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