Hot Stuff!: Investigation #4
Learners test two jars containing soil, one covered and one open, for changes in temperature. After placing the jars in the Sun, learners discover that the covered jar cools down more slowly.

Hot Stuff!: Investigation #1
Learners test two jars, one containing plain air and one containing carbon dioxide gas, to see their reactions to temperature changes.

It's a Gas!
Source Institutions
In this simple activity, learners see the production of a gas, which visibly fills up a balloon placed over the neck of a bottle.

Sublime Sublimation
Source Institutions
In this activity, learners explore sublimation by conducting experiments with dry ice.

Plugged in to CO2
Source Institutions
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.

Carbon Sequestration
Source Institutions
In this inquiry-based lesson, learners measure the biomass of trees, calculate the carbon stored by the trees, and use this information to create recommendations about using trees for carbon sequestra

Erupting Fizz
Source Institutions
This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.

Hot Stuff!: Testing for Carbon Dioxide from Our Own Breath
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.

Hot Stuff!: Carbon Dioxide Extinguishes a Flame
In this demonstration, learners observe vinegar and baking soda creating carbon dioxide (CO2) in a bottle. The gas is poured out of a bottle onto a candle flame, putting out the candle.

How Long Can You Hold Your Breath?
Source Institutions
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.

Earth Atmosphere Composition
Source Institutions
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.

Breathing Blue
Source Institutions
In this activity, learners test exhaled breath for carbon dioxide and learn how to use an indicator as a simple way to measure pH.

Inflate-a-mole
Source Institutions
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.

Raising the Level of Carbon Dioxide in Your Blood
Source Institutions
In this activity (on page 146 of the PDF), learners will explore the effects of increased carbon dioxide in the bloodstream.

Hot Stuff!: Testing Ice
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.

Hot Stuff!: Investigation #2
Learners test two jars containing hot water, one covered with plastic and one open, for changes in temperature.

"Boyle-ing" Water
Source Institutions
In this activity, learners explore Boyle's Law and discover that water will boil at room temperature if its pressure is lowered.

Mapping Greenhouse Gas Emissions Where You Live
Source Institutions
In this lesson plan, learners examine some of the of greenhouse gas emissions sources in their community.

Chemistry in the Kitchen
Source Institutions
In this kitchen chemistry activity, learners explore the chemistry of crystals by making sugar crystals, consider a common chemical reaction type responsible for the rising of muffins and cake in the

Bubble Suspension
Source Institutions
In this activity, learners observe as soap bubbles float on a cushion of carbon dioxide gas. Learners blow bubbles into an aquarium filled with a slab of dry ice.
