A property is a word used to describe a material or object and tells us something about it.
- Metals are usually shiny. The shine that we see when light reflects off the surface of a metal is called the lustre of the metal.
- Most metals are hard and they feel heavy.
- We say metals are dense as their particles are packed close together.
- Metals conduct electricity and heat well. (You will learn more about electricity next term. In Grade 6, you will learn about metals as conductors of electricity.)
- Metals are malleable (they can be shaped into flat sheets) and they are ductile (this means they can be made into thin wire)
- Most metals can be heated to high temperatures without melting or changing their shape, which is one of the reasons why pots and pans are made of metal. Can you think of any other reasons why pots and pans are made of metal?
Coins are made of different metals.
