| + | ===Meaning=== | ||
| + | [[File:Lightning.png|right|300px|thumb|Lightning is '''electricity''' travelling through the [[air]].]] | ||
| + | '''Electricity''' is a way that energy can be moved from one place to another. | ||
| + | |||
| + | : [[Noun]]: '''Electricity''' | ||
| + | : [[Verb]]: '''To electrify''' | ||
| + | : [[Adjective]]: '''Electrical''' | ||
| + | ===About Electricity=== | ||
| + | : We use '''electricity''' to power [[Electrical Appliance|appliances]] in the home. | ||
| + | : '''Electricity''' usually flows through metal wires. | ||
| + | : Sometimes '''electricity''' travels through the air. If it travels a short distance it is called a spark. If it travels from the clouds to the ground it is called [[lightning]]. | ||
| + | : If '''electricity''' travels through an animal the animal feels an [[Electrical Shock|electrical shock]]. | ||
| + | |||
| + | ==Key Stage 3== | ||
| + | ===Meaning=== | ||
| + | '''Electricity''' is a flow of [[electron]]s that allows [[energy]] to be [[Energy Transfer|transferred]] (usually along a wire) from one [[Energy Store]] to another. | ||
| + | |||
| + | ===About Electricity=== | ||
| + | : Different [[Electrical Component]]s can '''transfer energy''' to different [[Energy Store]]s or can cause other [[Energy Transfer]]s. | ||
| + | |||
| + | ===Examples=== | ||
| + | {| class="wikitable" | ||
| + | |- | ||
| + | |'''Filament Bulb''' | ||
| + | |'''Buzzer''' | ||
| + | |'''Motor''' | ||

| + | |[[File:Motor.png|center|200px]] | ||
| + | |- | ||
| + | | style="height:20px; width:200px; text-align:center;" |'''Electricity''' [[Energy Transfer|transfers energy]] into the [[Thermal Energy Store]] of the [[filament]] inside the [[Electrical Bulb|bulb]]. Some [[energy]] is then transferred away from the [[Electrical Bulb|bulb]] by [[light]] [[radiation]]. | ||
| + | | style="height:20px; width:200px; text-align:center;" |'''Electricity''' causes the buzzer to [[Energy Transfer|transfer energy]] away by [[sound]] [[radiation]]. It also [[Energy Transfer|transfers energy]] into the [[Thermal Energy Store]] of the buzzer as the buzzer gets hotter. | ||
| + | | style="height:20px; width:200px; text-align:center;" |'''Electricity''' [[Energy Transfer|transfers energy]] into the [[Kinetic Energy Store]] of the motor when it accelerates. It also [[Energy Transfer|transfers energy]] into the [[Thermal Energy Store]] of the motor as the motor gets hotter. If the motor is used to lift an [[object]] then [[Energy Transfer|energy is transferred]] into the [[Gravitational Potential Energy Store]] of the object. | ||
| + | |} | ||
| + | |||
| + | ==Key Stage 4== | ||
| + | ===Meaning=== | ||
| + | '''Electricity''' is an [[Energy Transfer|energy transfer]] caused by the flow of [[electron]]s or [[ion]]s though a [[medium]]. | ||
| + | |||
| + | ===About Electricity=== | ||
| + | : [[Electricity]] can perform [[Work Done#Work Done by Electricity|electrical work]] as the [[Electrostatic Field|electrostatic field]] inside a [[wire]] provides a [[force]] to move the [[electron]]s (or [[ion]]s). | ||
| + | [[Electricity]] has two [[property|properties]] that can be used to describe it: | ||
| + | *[[Electrical Current|Current]] - The rate of flow of [[Electrical Charge|charge]]; <math>I=\tfrac{Q}{t}</math> | ||
| + | *[[Potential Difference]] - The [[Work Done|work done]] per unit [[Electrical Charge|charge]]; <math>V=\tfrac{E}{q}</math> | ||

Key Stage 2
Meaning
Lightning is electricity travelling through the air.
Electricity is a way that energy can be moved from one place to another.
About Electricity
- We use electricity to power appliances in the home.
- Electricity usually flows through metal wires.
- Sometimes electricity travels through the air. If it travels a short distance it is called a spark. If it travels from the clouds to the ground it is called lightning.
- If electricity travels through an animal the animal feels an electrical shock.
Key Stage 3
Meaning
Electricity is a flow of electrons that allows energy to be transferred (usually along a wire) from one Energy Store to another.
About Electricity
- Different Electrical Components can transfer energy to different Energy Stores or can cause other Energy Transfers.
Examples
| Filament Bulb | Buzzer | Motor |
 |
 |
 |
| Electricity transfers energy into the Thermal Energy Store of the filament inside the bulb. Some energy is then transferred away from the bulb by light radiation. | Electricity causes the buzzer to transfer energy away by sound radiation. It also transfers energy into the Thermal Energy Store of the buzzer as the buzzer gets hotter. | Electricity transfers energy into the Kinetic Energy Store of the motor when it accelerates. It also transfers energy into the Thermal Energy Store of the motor as the motor gets hotter. If the motor is used to lift an object then energy is transferred into the Gravitational Potential Energy Store of the object. |
Key Stage 4
Meaning
Electricity is an energy transfer caused by the flow of electrons or ions though a medium.
About Electricity
- Electricity can perform electrical work as the electrostatic field inside a wire provides a force to move the electrons (or ions).
Electricity has two properties that can be used to describe it:
- Current - The rate of flow of charge; \(I=\tfrac{Q}{t}\)
- Potential Difference - The work done per unit charge; \(V=\tfrac{E}{q}\)
