Vocabulary
Define Energy
The ability to do work
Energy generated by the flow of water
Hydropower (Water Power) Energy
What is Kinetic Energy?
Kinetic Energy is the energy of motion! As long as an object is moving at the same velocity, it will maintain the same kinetic energy.
Is natural gas a renewable source of energy? Why or why not?
No! Natural gas comes from rock formations under the surface of the Earth.
Natural gas is a product of decomposed organic matter, typically from ancient marine microorganisms, deposited over the past 550 million years.
It will take hundreds of millions of years to form again and is not easily replaced.
The law of conservation of energy states that energy can neither be created nor destroyed - only ________________ from one form to another
converted, changed, or transformed
Define Renewable Energy and give an example
Energy that's collected from renewable resources or naturally rechargeable in a lifetime.
(Sun) Solar Energy, (Air)Wind Energy, (Water)Hydro Energy, and (Heat from the Earth) Geothermal Energy, Biomass
Light and heat energy generated by the Sun
Solar Energy
What is Potential Energy?
Potential Energy is the stored energy an object has because of its position or state. You can think of potential energy as kinetic energy waiting to happen.
True or False: Coal, Geothermal energy, and Oil are all Non-Renewable Energy sources.
False!
Coal, oil, and natural gas are all Non-Renewable Energy sources.
When energy moves from one place to another
Energy Transfer
Define Non-Renewable Energy
A natural source that cannot be replaced and will be used up.
What is renewable energy?
Energy that we can replace easily.
Energy that comes from atoms and molecules and how they interact.
Chemical Energy
True or False: Most of the energy that is used today comes from Non-Renewable Energy sources.
True! About 85% of the world uses Non-Renewable Energy sources.
About 15% of the world uses Renewable Energy sources.
Name the transfer
Toasting bread using a toaster
A toaster transfers electric energy taken from the electrical outlet into thermal energy which is heat
Define Pollution and give an example
ANYTHING that makes the Earth unhealthy.
Litter, car emissions, oil spills, factory emissions, etc.
Name THREE types of fossil fuels
Coal, oil, and natural gas.
The Earth gets a lot of its energy from this?
The Sun
True or False: Fossil Fuels are expected to run out in 50-100 years.
true
Name the transfer
A car backing out of the driveway
chemical energy to motion or kinetic energy
Define Fossil Fuels and give an example
a natural fuel such as coal, oil, or natural gas that's made from the remains of organisms that lived hundreds of millions of years ago.
Do you know any other types of renewable energy sources aside from solar, water, and wind?
Geothermal (from Earth's Core) and Biomass (From natural materials like compost and animal waste)
Anything that is moving has energy. This is also called __________ energy.
Kinetic or Mechanical Energy
What are some costs or negative effects of using Fossil Fuels?
Pollution, a Non-Renewable Energy source, will run out very soon, can take millions of years to create more.
Name the transfer
Drying your clothing in a dryer
electrical energy to heat energy
