With rising oil prices and increasing concerns over global warming, the pressure is on for engineers to develop alternative sources of energy. Among the new technologies being developed are hydrogen fuel cells, which young scientists...

Future mechanical engineers and automotive technicians read about various solutions to using gasoline in cars. Included are electric, fuel-cell-powered, and hybrid vehicles.

Fuel cells are being called the "energy source" of the future. Allow your high school chemistry class to construct a miscroscale fuel cell, complete with all components to generate energy. This engaging activity will allow them to apply...

Science pupils choose from twelve questions about five different types of fuel: hydrogen, ethanol, crude oil, natural gas, and coal. They construct a table to compare them and then determine the best fuel. Your physical science class...

High schoolers conduct an experiment using the reaction of hydrogen and oxygen. After pairs balance the chemical equation for making water, they mix different ratios of hydrogen and oxygen in a chemical reaction. Classmates...

Students investigate which metal is best to use as storage material in hydrogen cars. In this chemistry instructional activity, students differentiate endothermic and exothermic reactions. They write a reflection paragraph about what...

Young scholars construct a simple robotic energy transformer. In this space science lesson, students explain how energy is transformed from one form to another. They identify the different uses of robotic devices.
