Energy
Vocabulary
1) Resource-- something that you can depend on to do something or provide something
2) Renewable resource-- a source of energy that will never run out; typically it is nature related (ex. Hydroelectricity)
3) Nonrenewable resource-- a source of energy that will eventually run out; it can be in a situation where no more is produced ever or it could be that it can be produced but it is used a lot faster than it is produced
4) Fossil Fuels-- sources of energy that produce gasses that can be harmful to the environment.
6) Hydroelectric energy-- energy that is made by water flowing through a dam
7) Geothermal energy-- water is heated by rocks in the ground and the steam that is produced is used in a turbine which allows for energy to be transformed and put to use
8) Nuclear energy-- when energy is created through splitting an atom (Uranium); this is called nuclear fission
9) Wind energy-- in windy places, people set up turbines to catch the wind; the wind turns the blades which turns a generator which makes the electricity
10) Biomass-- organic matter is burned to create electricity; ethanol is created through biomass
11) Hydrogen fuel-- this is a machine that is used mostly in cars where the protons and neutrons of a hydrogen atom are separated which creates the energy
12) Conservation-- using resources wisely or in a manner that will allow them to last for a longer amount of time
13) Preservation-- saving something

Sources of Energy To Know
1) Coal
Coal is a nonrenewable source of energy that creates pollution. It is made from plant remains that are pressed together over a very long period of time. Coal is usually burned to create the energy that people need. A lot of energy that the United States uses comes from coal.
Coal causes pollution that can harm the environment.
2) Oil
Oil is a nonrenewable source of energy that can be bad for the environment. It is made from the remains of animals and plants that live in the ocean. Oil is a huge source of energy for the United States. Oil is used for gasoline and is used in a variety of machines to power them.
3) Natural Gas
Natural gas is a nonrenewable source that is made the same way as oil, being that it is made under the ocean. It has a variety of gasses inside of it and is used a lot as an energy source. Natural gas is burned to get energy. It produces less pollution than coal and oil, but it still produces some pollution.
4) Nuclear Energy
Nuclear energy can be considered renewable or nonrenewable since you must have the atoms to split in order to make the energy and those atoms are nonrenewable. Nuclear energy is made by splitting an atom, a process called nuclear fission, of Uranium to create energy. This source of energy does not pollute the air, however it does make the water that it uses to cool of rods very hot which can kill the underwater animals in that area.
5) Solar Energy
Solar energy is a renewable source of energy that captures the light from the sun and turns it into energy that humans can use. This is done through layers of silicon and other materials. This is done in a cell. When you put these cells together, it forms a panel. Solar panels do not cause any pollution, but the price for the solar panels is very high.
6) Hydroelectric Energy
Hydroelectric energy is created by water moving through a dam and turning the blades of a turbine. These turbines turn the generator which produces the electricity for human use. Hydroelectric power does not cause any pollution, however it can cause problems for the animals and people that live around the body of water. The people above the dam will be getting a lot more water while the people below the dam will have a lot less water.
7) Geothermal Energy
Geothermal energy is a renewable source of energy that uses the power of underground rocks. The conditions must be perfect for this to work. There is water that is pumped into the ground and heated by the underground rock. The steam produced by the heat of the water spins the turbine which spins the generator and allows the energy to transform into the type of energy that we need. This type of energy produces no pollution at all.
8) Wind Energy
Wind energy is a renewable source of energy that is created through wind turbines. The wind turns the blades of the turbine which turns the generator. This creates the energy that we need. Wind energy has no air pollution, but can be a problem in living areas with the shadows of the blades as well as the noise of the whole turbine.
9) Biomass Energy
Biomass energy is created when organic matter is burned. This burning of organic matter does release CO2 which can be very harmful to the environment. Also, the crops that are used in the biomass part could be used for food instead of just burning them.
10) Hydrogen Fuel Cell
Hydrogen fuel cells produce energy by splitting hydrogen atoms into protons and electrons. Oxygen is needed to help with the process. Hydrogen fuel cells do not produce any pollution.

Coal is a nonrenewable source of energy that creates pollution. It is made from plant remains that are pressed together over a very long period of time. Coal is usually burned to create the energy that people need. A lot of energy that the United States uses comes from coal.

ENERGY IS NEVER LOST OR CREATED, IT IS JUST TRANSFORMED!!!
This may sound hard to believe, but it can be thought through with easy examples.
One example would be charging your phone. The energy goes from the outlet in the wall, through the cord, and into your phone. No energy is ever lost or created, it is just transformed into different types of energy.
This means that when you are talking about a ball rolling back and forth, the moments where it pauses before going the other way is where the ball has more potential energy than kinetic energy. The ball always has the same amount of energy, it is just in different forms.
