- Electricity is a form of energy.
- Electricity comes from the conversion of energy sources, such as oil, coal and gas.
- Wind, water and solar energy are sustainable sources that can be used to generate electricity.
- Electricity is used to power household items but it can also be dangerous.
- Benjamin Franklin proved lightning is electricity.

The facts about electricity
Electricity is the flow of energy. All matter has atoms. Atoms have at their centre a nucleus, containing protons and neutrons. Surrounding the nucleus are electrons. When there is an imbalance of protons and electrons, electrons are released from the atom. This flow is called an electric current.
An electric circuit provides a path for an electric current to follow.
are used to change forms of energy, including fossil fuels (coal and oil) and renewable sources (water, wind, and solar), to produce electricity.
Electricity is used to power household items but can be to humans, causing burns, electric shock – even death. There are tips you should follow to stay safe, and .
An electric charge that doesn't flow, or move, is called .
According to the Global Hydrology and Climate Centre, Benjamin Franklin performed the first systematic, scientific study of lightning during the second half of the 18th century.
While others had previously noted the similarity between laboratory sparks and lightning, Franklin was the first to design an experiment which conclusively proved the electrical nature of lightning.
