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.

In this activity, learners discover if carbon dioxide has an effect on temperature.

In this lesson plan, learners examine some of the of greenhouse gas emissions sources in their community.

This board game teaches learners about energy decision making. Players select cards that determine the transportation and home design that will influence their expenses as they play.

This is an activity (located on page 3 of PDF under Hockey Sticks Activity) about composites, materials made of 2 or more different components.

In this activity, learners imagine what the world might look like if we could build an elevator to space!

In this activity, learners investigate various appliances and electronics, discovering how much energy each uses and how much carbon dioxide (CO2) is released to produce that energy.

In this activity (on page 142 of the PDF), learners will compare breathing rates before and after hyperventilation to explore how reduced carbon dioxide levels in the blood lower the need to breathe.

Ocean acidification is a problem that humans will have to deal with as we release more and more carbon dioxide into the atmosphere.

In this activity, learners explore how acids can dissolve eggshells leaving behind a membrane-covered bouncy egg.

In this activity, learners explore the concepts of density and basic chemical reactions as they create a homemade lava lamp effect using water, oil, food coloring, and Alka-Seltzer tablets.

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, 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.
