Hi class.
In this unit you are learning about electricity.
- Some materials let the electricity pass: they are conductors
- some materials don’t let electricity pass: they are insulators
Classify these materials.
Look at this wire (cable):
- there is metal inside: the electricity can pass. METAL IS CONDUCTOR
- there is plastic outside: electricity cannot pass. It protects us. PLASTIC IS AN INSULATOR.
