What better way is there to introduce conservation of mass than a few simple experiments? Young chemists conduct two chemical reactions, take the masses of reactants and products, then compare their results to determine...

Scientists can't observe bonds breaking or forming, so how do they distinguish between exothermic and endothermic reactions? Young scholars complete two experiments to do just that. They monitor temperature change and calculate the...

Intended as a follow up to the Protecting Your Drinking Water activity, young environmentalists use their assessment of the a hypothetical town's water supply to debate the installation of underground chemical storage tanks. With...

Radiation has numerous real-world applications, some of which are relatively safe while others can be extremely hazardous. In this nuclear chemistry project, young scientists choose a practical use of nuclear reactions to...

The United States is the world's largest producer of biofuel. During an in-class investigation, young scientists produce their own biodiesel. They burn a sample of it to determine the heat of combustion. Then they discuss the...

Energy conservers investigate gravel size to discover if it impacts the amount of oil recovered in the extraction process. 

A bioremediation expert cautions against the concentration of detergents and other chemicals used to clean up oil spills. The clean-up can be a nightmare of its own when toxic agents are used.
