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.

Learners use a candle to investigate the products of combustion. When a glass rod is held over a lit candle, the candle flame deposits carbon on the rod.

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.

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 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 activity, learners explore Boyle's Law and discover that water will boil at room temperature if its pressure is lowered.

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.

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 experiment, learners will explore whether increased carbon dioxide makes our oceans more basic or more acidic.

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.

In this activity, learners investigate the properties of graphene and graphite.

Learners experiment with a piece of Silly Putty® by stretching, bouncing, and snapping it. They then create flubber, a similar substance, by mixing diluted glue and a solution of sodium borate.

"Sublimation Bubbles" allows learners to explore how some solid materials, such as dry ice, can phase change directly from their solid to gaseous form.
