Conductors and Insulators
Learning Objective:
Make and explain predictions about circuits.
Support predictions by demonstration circuits, or circuit diagrams.
To recognise which materials are better conductors than others.
Starter: Match up activity

2. Match up the components to the description
Short description
 Switch
Turns the circuit off if too much current flows
Fuse
Several cells connected together
Ammeter
A very good conductor
Connecting Wires
Changes electrical energy into heat and light energy.
Bulb
Instrument used to measure the size of the current.
Battery
Opening and closing them makes circuits complete or incomplete.

Conclusion.
What trends do you notice?
Are there any exceptions?
In your own words explain why the bulb lights when some materials are placed between the crocodile clips and not others?

7. Words – pencil, energy, flow, metals, insulators

Conductors are usually _______. This is because metals have lots of tiny particles called ELECTRONS that can move about and carry electrical _______.
Other materials are generally _________. This means that electrical current cannot _____ through them.
The only conductor that is not a metal is carbon, like in your _______!
