Activity #17 Co2 From Alka Seltzer

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...

How does a change in pH affect the ocean ecosystem? Scholars explore the idea by making an acid-base indicator in part seven of the 10-installment Discover Your Changing World series. First, they explore impacts of carbon dioxide in...

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...

It is colorless and scentless, but it makes a large impact on the environment. Learners explore carbon dioxide emissions and what they mean for the environment using an interactive graph. They review changes over time and how they impact...

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...

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...

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...

Students perform an experiment comparing the impacts of CO2 on salt water and on fresh water. In a short demonstration, students examine how distilled water and seawater are affected differently by increasing carbon dioxide in the air.

Carbon is all around us, as shown in this cartoon animation. The carbon cycle is portrayed simply and accurately with fun cartoon plants and animals. Use this video in an elementary or junior high class to facilitate your learners'...

Students study the scientific evidence about carbon dioxide emissions. They learn to calculate the amount of energy used by different appliances. They complete a worksheet which analyzes the amount of energy that their home uses.
