Vocabulary

Meaning

condensation

Drops of water when water vapour or steam touches a cold surface.

evaporation

To turn from a liquid into a gas.

freezing

A liquid becomes a solid because of low temperature.

melting

To change from a solid to a liquid through heat or pressure.

melting point

The temperature at which a material melts.

particles

A tiny amount or small piece.

precipitation

Rain, snow, sleet, dew etc formed by condensation of water vapour in the atmosphere.

vibrations

Shakes with small, quick movements.

water vapour

Water in the gaseous state

Key facts to remember:

The particles in gas are spaced out.

The particles in liquid are closer together than a gas.

The particles in a solid are packed tightly together.

Solids, liquids and gasses can change state when they are heated or cooled.

States of Matter Year 4

Key Concepts

​

Particles are what materials are made from. They are so small that we cannot see them with our eyes. The properties of a substance depend on what its particles are like, how they move and how they are arranged.

Knowledge end points:

To identify common appliances that run on electricity.

To construct a simple series electrical circuit and name its basic parts (cells, wires, bulbs, switches and buzzers)

To identify whether or not a lamp will light in a simple series circuit based on whether there is a complete loop with a battery.

To recognise that a switch opens and closes a circuit.

To recognise some common conductors and insulators and know metals are good conductors.

Methods and processes:

To draw accurate and careful diagrams

To use pictorial representations of simple circuits.

To observe patterns when bulbs light up and when they will not based on the use of a switch opening and closing a circuit.

To draw conclusions about why results have been found.

​

What is a switch and how does it work?

​

Vocabulary

Meaning

appliances

A device or machine in your home that you use to do a job such as cleaning or cooking. Appliances are often electrical.

component

The parts that something is made up of.

conductor

A substance that heat or electricity can pass through or along.

current

A flow of electricity through a wire or circuit.

generate

Cause it to start and develop.

insulator

A non-conductor of electricity or heat.

Key facts to remember:

Electrical appliances can use batteries or mains electricity.

A circuit can have different components.

The amount of energy a circuit has will change the way different components work.

If something is a conductor, electricity can pass through it.

If something is an insulator, electricity can not pass through it.

Electricity Year 4

Key Concepts

Electricity is generated using energy from natural sources such as the sun, oil, water and wind. These can also be called fuel sources.

How does a circuit work?

• A complete circuit is a loop that allows electrical current to pass through the wires.
• A circuit contains a battery, wires and an appliance that requires electricity to work.
• A switch can break or reconnect a circuit
• When the switch is off, the current cannot flow.
• This is not the same as an incomplete circuit.

To use recognised scientific symbols when representing a simple circuit in a diagram.

Methods and processes:

To draw accurate and careful diagrams.

To use recognized symbols in circuit diagrams.

To observe patterns in when bulbs light up and when they will not.
