Vocabulary
A tool or piece of equipment?
What is a device?
A resource that cannot be easily remade
non-renewable resource
A fossil fuel that forms underground from partially decomposed plant material
coal
A device that converts stored chemical energy to electrical energy
battery
A large wheel that rotates when pushed by water, wind, or steam
turbine
Why energy is used in the form of electricity instead of other forms
Electricy travels along wires and is easily delivered to homes
First or most significant
primary
A resource that can be easily remade
renewable resource
A material such as coal, gas or oil that is burned to produce heat or power
fuel
Energy from the sun that is converted into thermal or electrical energy
solar energy
A device that reduces the amount of pollutants that leave factory smokestacks
scrubber
How a nuclear power plant is different from a coal power plant
A coal power plant burns coal, a nuclear power plant changes particles of matter to create energy
To look at something closely, to watch
observe
Three common fossil fuels

The process of burning something
combustion
The source of all energy on earth
sun
A fossil fuel in the gas state
natural gas
The energy produced by heat within the earth
geothermal energy
A machine that converts mechanical energy into electrical energy
generator
How a turbine is used to harness the energy of the wind or water (2 steps)
Wind or water can use kinetic energy to spin the turbine. The turbine spins the generator which makes electricity.
