Metals are very useful materials, with properties such as strength, stiffness and electrical conductivity.
Results of scientific enquiries can be recorded in different ways including charts and tables.
All metals conduct electricity, but some metals are better electrical conductors than others.
Materials are chosen for particular jobs based on their properties.

Not all metals are electrical conductors.

Pupils will test materials for conductivity, but teaching slides will emphasise that all metals are electrical conductors.

Metal - Most metals are strong, hard and shiny materials. They are good conductors of heat and electricity.
Electrical conductor - An electrical conductor is a material that allows electricity to pass through it easily.
Conduct - If a material conducts electricity or heat, it means the electricity or heat can pass through it easily.
Electrical insulator - An electrical insulator is a material that does not allow electricity to pass through it easily.
