Types of Energy
This is the energy you can hear when a bell rings.
Sound
This resource uses water stored behind dams to make electricity.
Hydroelectric
Coal, oil, and natural gas are examples of this kind of resource.
Fossil Fuel
Sound, light, heat, and electric currents can move energy from one place to another. True or False?
True
Turn off this in a room when you leave to save electricity.
Light
This type of energy comes from the Sun and helps plants grow.
Solar
Energy from the Sun is called this type of renewable energy.
Solar
This nonrenewable resource is formed from ancient plants and animals and is often used for cars.
Oil
When you hold a mug of hot cocoa, heat moves from the cocoa to your hands. True or False?
True
This type of resource is one we need to conserve.
Nonrenewable
The energy an object has because it is moving (for example, a rolling ball).
Motion
Wind turbines use moving air to make electricity. Why is wind considered renewable?
Because you can't run out of wind.
Why are nonrenewable resources considered limited?
Because they take millions of years to form.
In a circuit, this is the pathway that energy travels through.
Wires
What part of the circuit pushes the energy through?
Battery
This form of energy comes from tiny charged particles moving through wires.
Electrical
Name two benefits of using renewable resources
lower greenhouse gas emissions; less air pollution; wont run out
Name one environmental effect of burning fossil fuels for energy.
increased air pollution, greenhouse gas emissions, or acid rain
In a circuit with a light bulb how do you know the energy is moving?
The light bulb lights up.
If the circuit is not working is that considered open or closed?
open
The energy stored in foods and fuels that can be released when they are burned or eaten.
Chemical
Give one example of a renewable resource and explain one way its use can affect the environment
Ex: Solar energy — can reduce air pollution; but large panels or land use can affect habitats
This type of energy creates radioactive waste.
Nuclear
With anything that has to be plugged in, what is the initial energy source?
Electric energy
In a circuit with a buzzer what are the initial and final energy forms?
