Observations
It’s electric!
Many things need electricity to work. Batteries are one source of electricity.
Electricity can also be obtained by plugging things into a socket in the wall.
This electricity comes from wires that go into your home. Never place anything
but an electrical plug into a socket or you can receive an electric shock that
can kill or badly hurt you!

Science activity
Which of these things work when they are plugged into a wall socket? Which
ones work with batteries? Draw a line joining each one to the correct word.
The first one is done for you.

socket batteries

Science exploration
Take extra care - ask an adult to supervise you.
Cut out pictures of things that use
electricity. Label each picture to show
if it uses batteries or plugs into a socket.

Flashlights and cell use batteries.

Be with electricity! It can

Conductors and Insulators

A conductor is a material that allows electricity to flow through it.
An insulator is a material that electricity cannot flow through.

To determine whether an object is a conductor or insulator, you can build a simple

circuit with a battery, light bulb, and three pieces of wire.

Touch the free ends of the wire to the object you are testing. If the light bulb lights up, the
object is made from a conductor. if it does not, the object is made from an insulator.

Complete the table. Predict whether each item is made from a material that is a conductor or
insulator. Then test each item to determine if it is made from a conductor or insulator.

Object Prediction: Conductor or Insulator? Result: Conductor or Insulator?
