Electricity is very useful but can also be dangerous - so take care!

# Energy - Electricity, Bulbs and Batteries

This quiz addresses the requirements of the National Curriculum KS1 Science for children aged 5 and 6 in years 1 and 2. Specifically this quiz is aimed at the section dealing with energy, electricity, bulbs and batteries.

In school you will have learned about electricity, switches, batteries and bulbs. It is very useful. Electricity powers bulbs and keeps our lights on. It runs our televisions and computers, and makes our fridges work. Electricity can be turned on and off by switches. Some things need batteries to work. Batteries store energy. But the energy in batteries does run out. These questions are about using electricity.

1.
This is a very simple electrical circuit. A wire goes from the battery to the bulb. Another wire goes from the bulb back to the battery.

What colour is the battery?
Black
Brown
Red
Blue
The bulb lights up when the electricity can go all the way round the circuit
2.
Look again at this simple electrical circuit. Where does the energy come from to make the bulb light up?
The bulb
The air
The battery
The wires
The electricity goes through the wires, but the energy comes from the battery
3.

Alice takes away one of the wires. What happens to the bulb?
The bulb stays on
The bulb blows up
The bulb does not light up
The bulb melts
What will happen if Alice puts the wire back again? - The bulb will light up again
4.
The picture shows two light switches. Look at the switch on the left. The light will be:
Dim
Dull
On
Off
An I sign means ‘on’. An O sign means ‘off’
5.
The same picture of two light switches. Look at the switch on the right. The light will be:
Dim
Dull
On
Off
So, one light is on, and one light is off
6.
This is a battery. Batteries have two ends. The end at the top of this picture is called the plus (+) end. What is the other end of the battery called?
Plus (+)
Minus (-)
Earth
Electrical
Always put batteries in the right way round
7.
Sam has a remote control car. It is powered by a battery. What happens if the battery is flat?
The car will go faster
The car will go slower
The car will not go
The car will spin
A flat battery has lost all its stored energy
8.
Michael’s mobile is not working. The battery has run out. What should Michael do?
Throw his mobile away
Recharge the battery
Give his mobile to a friend
Mobile batteries are very small, but they store energy - just like other batteries
9.
Amy’s Mum is replacing an old light bulb. The new light bulb uses less energy. Why is this a good thing?
The new light bulb will cost less to run
The new light bulb is a funny shape
The new light bulb is a brighter colour
The new light bulb will use more energy
Less energy means lower bills and it uses less electricity
10.
Lucy wants to watch a show on the telly. She presses the button on the remote control to turn on the television. But nothing happens. What is most probably wrong?
The TV show has finished
She has the wrong channel
The batteries in the remote control need replacing
She has the wrong day
Remote controls need energy to work. They have batteries inside them
