Experimenting with Yeast Metabolism

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...

A short slide show to illustrate the density of carbon dioxide and monoxide. An interesting look at the safety aspects to prevent CO poisoning, and the biological mechanisms by which it does harm. This elaborates on the exchange of blood...

Split your earth science or environmental studies class into groups and give each a scenario card. Scenario cards describe the lifestyles of 10 different fictitious families, focusing on their energy usage. Carbon dioxide emissions are...

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

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...

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...

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...

Carbon is a key element in life on Earth. Where can it be found? Hear all about carbon's whereabouts and how it is used. Climate change is brought up along with human responsibility. This clip is great for a junior high or high school...

Students explain that carbon dioxide from any source reacts chemically with water to form carbonic acid. They will also be able to use the color changes of universal indicator to monitor the changing pH of a solution during a chemical...
