Unit: Energy

Grade 6 Term 2

Significant Concept• All things need energy to do work.

Unit Question• How do we get and use energy?

AoI Focus ~ Environments

• How forms of energy (renewable and non-renewable) are affecting our planet.

• How the future of energy use can change how we live and its future affects on the environment.

• The effects of our actions, attitudes and constructs, such as sustainable development and conservation

Fuels

• Can you name some different Fuels?

• What do we use them for?

• What different forms of Fuel exist?

• Can you give a definition for Fuels?

• Are Fuels valuable? If yes, why?

Fuel & Energy

• Fuels: the burning of something to allow things/work to happen.

• Fuels are sources of heat, light and movement (these are all forms of energy)

• Energy: is what burning fuels release to make things happen.

Energy

• Energy Is the Ability To Do Work• Energy comes in different forms:• Heat (thermal) • Light (radiant) • Motion (kinetic) • Electrical • Chemical • Nuclear energy • Gravitational

How is Energy used?

Renewable vs Non-renewable Energy

• Energy Sources Can be Grouped As Renewable or Nonrenewable

• Renewable - an energy source that can be easily replenished

• Nonrenewable -an energy source that we are using up and cannot recreate

Renewable Energy (Alternative Energy)

• Renewable energy sources including biomass, hydropower, geothermal, wind, and solar provide 7% of the energy used in the United States. Most renewable energy goes to producing electricity.

• Solar energy from the sun, which can be turned into electricity and heat

• Wind energy from moving air • Geothermal energy from heat inside the Earth • Biomass from plants, which includes firewood from trees,

ethanol from corn, and biodiesel from vegetable oil • Hydropower from hydroturbines at a dam

Non-renewable Energy

• The four nonrenewable energy sources used most often are:

• Oil and petroleum products — including gasoline, diesel fuel, and propane

• Natural gas

• Coal

• Uranium (nuclear energy)

Fossil Fuels

• Nonrenewable energy sources come out of the ground as liquids, gases, and solids. Crude oil (petroleum) is the only commercial non-renewable fuel that is naturally in liquid form. Natural gas and propane are normally gases, and coal is a solid.

• Fossil Fuels – fuels that come from fossils (dead organisms)

• Fossil Fuels Are Non-renewable, but Not All Non-renewable Energy Sources Are Fossil Fuels

• Coal, Natural Gas & Oil are Fossil Fuels • Nuclear Energy is not a Fossil Fuel
