# Electrical Vocabulary Check-up

In this worksheet, students will be checking their knowledge of the vocabulary used to discuss, describe and explain electrical circuits.

Key stage:  KS 2

Curriculum topic:   Electricity

Curriculum subtopic:   Circuit Diagrams and Symbols

Difficulty level:

### QUESTION 1 of 10

Science vocabulary is important because it allows us, as scientists, to talk about our learning and describe our knowledge and ideas with other scientists.

Some science words have meanings in other subjects, for example, factors, which is also a Maths word.

When we talk about electricity, a CELL is a source of electrical energy, which can also be called a battery. However, being very strict, a battery is made up of a number of cells.

There are names for the units of measure. The power provided by a battery is measured in Volts. The more Volts, the more energy!

Let's check out that science vocabulary for electric circuits!

When we are talking about electricity, a CELL is...

a very small room

a source of electrical energy

found in all plants and animals

Several cells together are called a...

circuit

prison

battery

The power provided by a battery is measured in...

centimetres

Watts

Volts

degrees

The device which 'breaks' a circuit is called a...

hammer

power-cut

switch

gap

The flow of electrical energy around a circuit is called the...

current

currant

charge

Current is measured in...

grams

Amps

miles per hour

We measure amps using...

an ammeter

an electricity meter

a voltmeter

The component in a hairdryer which produces movement is the...

switch

air

motor

The material used in all electrical circuits to keep us safe is called an electrical...

switch

insulator

conductor

When we draw our electrical circuits, we use...

pictures

signs

symbols

• Question 1

When we are talking about electricity, a CELL is...

a source of electrical energy
EDDIE SAYS
Plants and animals are made of cells, but not the same ones we use to supply electrical energy!
• Question 2

Several cells together are called a...

battery
EDDIE SAYS
Cells connected together are called a battery. Ever heard of a gun battery? That's a line of field guns that teams of soldiers would be using to shell the enemy in a battle. Line of guns = battery. Line of electric cells = battery.
• Question 3

The power provided by a battery is measured in...

Volts
EDDIE SAYS
Have a look at batteries at home and in school. They show their power in Volts written on the side.
• Question 4

The device which 'breaks' a circuit is called a...

switch
EDDIE SAYS
An open switch makes a gap or break in a circuit, stopping the flow of electricity.
• Question 5

The flow of electrical energy around a circuit is called the...

current
EDDIE SAYS
Watch the spelling scientists! Think of the 'e' as being 'e' for electricity! Otherwise you've got a thing like a small raisin (currant!!).
• Question 6

Current is measured in...

Amps
EDDIE SAYS
Amps is the unit of measure for electrical current. It's short for AMPERES.
• Question 7

We measure amps using...

an ammeter
EDDIE SAYS
An ammeter is short for Amp-Meter. Make sense?
• Question 8

The component in a hairdryer which produces movement is the...

motor
EDDIE SAYS
The fan which pushes air through the hairdryer is powered by a motor.
• Question 9

The material used in all electrical circuits to keep us safe is called an electrical...

insulator
EDDIE SAYS
Insulators stop the flow of electricity so that the appliances we use everyday are safe to use and handle.
• Question 10

When we draw our electrical circuits, we use...

symbols
EDDIE SAYS
Symbols are used to represent components in a circuit. All scientists recognise these symbols as meaning the same components.
