Every Breath You Take

Ninety-seven percent of scientists who study climate agree that human activity is warming the planet. Learners explore carbon dioxide as a greenhouse gas, a gas causing this warming, through a hands-on experiment. Once complete, they...

Some like it hot! Scholars observe both exothermic and endothermic reactions as part of the carbon dioxide oxygen cycle. First, scientists demonstrate (or watch) a chemical reaction to create pure oxygen using fire for confirmation....

Does carbon dioxide really affect temperatures across the world? This fifth installment in a six-part series investigates the relationship between carbon dioxide and global temperatures. Graphs created from genuine data help young...

Can your breath change the acidity in a liquid? A lesson begins with a demonstration that proves it can. Then scholars perform an experiment to determine if other gases can change the pH of liquids. Finally, they research how this...

There's not much to this video. Steve Spangler and his twin sons visit 9 News and perform the classic chemical reaction between vinegar and baking soda to produce carbon dioxide gas. Where the value is in this video clip is that they set...

Watt is going on here? Middle schoolers are learning about energy use and carbon dioxide emissions! In the first part of this instructional activity, learners measure how much energy different appliances consume and calculate the amount...

Where does all of the carbon dioxide come from that is supposedly leading to climate change? Earth science pupils test animal, plant, and fossil fuels as sources in this investigation. Using an indicator, BTB, they are able to detect the...

Precipitation reactions are always interesting. How about one that forms a precipitate using a gas? Chemists of any age will enjoy this twist on a standard solubility lab. Partners observe the lack of interaction between sodium hydroxide...

Why don't we just capture carbon dioxide in the air and store it somewhere else? A hands-on lesson allows scholars to explore a complex concept. First, they will create a carbonated beverage, and then they will determine if liquid...

Scientists can model global surface temperature with and without considering human emissions, but does do these factors really make a difference? Two interactive graphs demonstrate some factors that affect climate change. The first graph...
