LO: to investigate the conductivity of different materials
- Using what you have learnt making circuits and switches, can you make a circuit so you can test the conductivity of different materials
- What equipment will you need?
This is the sort of circuit you need. There should be a break in the circuit where you will place the object to be tested for conductivity.
LO: to investigate the conductivity of different materials
Before you start, what materials do you think are:
Electrical insulators
Electrical conductors
LO: to investigate the conductivity of different materials
Insulators
Conductors
Here is another way to record your findings:
Electrical Insulators
Electrical Conductors
Plastic tray
Radiator pipe
Book
Fork
Piece of paper
scissors
Why might there be 2 blank boxes?
Electrical Conductors
Electrical Insulators
Metal
Radiator pipe
Fork
Scissors
Plastic tray
Non-metal
Piece of paper
Book
Can you generalise about different materials?
- Electrical conductors are made from…
- Electrical insulators are made from…
