Students use a Palm loaded with chemistry software to assist them in gaining information presented in a lesson plan about basic chemistry principles. They perform a basic chemistry demonstration for their class using information from...

It's a gas. Middle schoolers build a biogas generator following the directions in this resource. After a few days of observation, they demonstrate that the gas given off by the decomposing manure is flammable. The activity concludes as...

An outstanding lesson awaits your physics fledglings! After reading about how hydrogen can act as an energy carrier, they examine the electrolysis of water using solar power. They test the gases produced for flammability and will...

Students use the internet to research air bags in cars and trucks. In groups, they discover air bags history and the safety issues surrounding them. They create their own design of a new air bag and test it using a raw egg in...

Discover the properties of water-loving and water-hating surfaces. In the seventh installment of a nine-part series, scholars explore hydrophilic and hydrophobic surfaces by conducting an experiment. They observe surface coatings,...

Explore capillary action from different perspectives. In the fourth installment of a nine-part series, scholars perform several experiments to observe capillary action. They look at the meniscus of water in a glass, observe capillary...

Make the strongest beam possible using taffy? Groups mold a taffy-water mixture into a beam and a reinforcing material of their choice. To finish the final installment of a two-part series, participants test its strength by adding...

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...
