|Generating Electricity: Wind and Water||
Keywords: electricity, electricity generation, hydro-electricity, Lend an Experiment (LEx), wind, wind energy, wind turbines
A match made in energy heaven, wind and water are wonderful sources of clean, renewable energy. Let us see what goes into this electricity generation by making some wind and water turbines ourselves!
This activity is part of the LEx (Lend an Experiment) Climate Kit. Students generate their own wind or hydro electric power by constructing wind/water blades, exploring how mechanical energy from external sources can be harnessed and turned into electrical energy. The effect of different gear ratios can also be explored.Read More...

Generating electricity using just a magnet and a wire?
A useful voltage can be obtained by moving a wire perpendicularly through a magnetic field; the electrons in the wire are pushed to one side creating a flow of electricity which is perpendicular to both the magnetic field and direction of wire motion.Read More...

What effect does electricity have on the human body?
This article discusses the physiological effects of electric shock as well as a protective device installed in typically dangerous areas: ground fault circuit interrupters.Read More...
