Properties of Metal
Feels...
1. smooth and is shiny when polished or freshly cut
2. hard
3. cold
4. heavy - iron is very dense
Conducts...
1. electricity - an electrical charge passes through iron easily
2. heat - iron like other metals is a good thermal conductor
3. sound - thin sheets of iron make a 'boinn.n.g.g' noise when hit
4. magnetic force - it is one of only three metals which are attracted to a magnet
Find out the names of the other two metals which attract a magnet.

Resists...
1. a weight - iron is strong and makes a good building material
2. movement - the bonds inside iron can withstand stresses and movement
3. a knock
Why do you think iron bars are put in concrete used in buildings?

Changes...
1. if heated at a very high temperature iron becomes malleable and easy to shape, bend, twist or mould
2. if stretched - some forms of iron can be pulled into wire because it is not brittle and does not break easily
3. if exposed to air and water together the iron rusts
Find out the scientific name for rust
