I can determine the sources and types of energy resources.

Review

Petroleum: fossil fuel from remains of plants and animals that died millions of years ago

Natural Gas: a mixture of combustible gases, mostly methane and ethane, found trapped in spaces of some sedimentary rocks, often along with petroleum deposits

Coal: a hard black or dark brown sedimentary rock formed by the decomposition of plant material, widely used as a fuel

Uranium / Nuclear: energy from splitting the nucleus of a uranium atom apart.

Propane: energy rich gas found with petroleum and natural gas.

Biomass: plant and animal material, especially agricultural waste products, used as a source of fuel

Hydropower: electric power generated using water power

Geothermal: relating to or produced by the heat in the interior of the Earth

Solar: using the Sun's radiation as a source of energy

Wind: air moving across the surface of the planet or through the atmosphere from the uneven heating of Earth's surface

Mechanical (Motion) EnergyMechanical energy is the movement of a substance form one place to another. Thermal Energy (Heat Energy)Thermal energy is the internal energy in substances - the vibration or movement of atoms and molecules in substances. Electrical EnergyElectricity is the movement of electrons.

Kinetic Energy

Sound EnergySound energy is the movement of energy through substances in longitudinal waves.Radiant Energy (Light Energy)Radiant energy is electromagnetic energy that travels in transverse waves.

`

Nuclear EnergyNuclear energy is the energy stored in the nucleus, or center, of an atom. When this center splits, it releases a large amount of energy.

Chemical EnergyChemical energy is stored in the bonds of molecules and atoms - in fuels, such as charcoal, gasoline, and even food.

Potential Energy

Stored Mechanical EnergyStored mechanical energy stored in objects by the application of force.

Gravitational EnergyGravitational energy is the energy of place or position.

Energy Conversions: I can determine how energy is transformed.

Because energy exists in many forms, it can be transformed from one form to another (conversion). Energy is "lost" as heat during each energy conversion. The more transfers and conversions there are, the more opportunities there are for energy to be "lost", most often as waste heat from friction. When energy changes to the same form, it is called an energy transfer.

For example:Energy conversion - the chemical energy in a cheeseburger is

changed to mechanical energy for your muscles to move.Energy transfer - the energy of the main crankshaft of a car

transfers to the tires, which makes it move (mechanical to mechanical)
