Ships have been made of metals or alloys of metals
Students learn to:
- account for the differences in corrosion of active and passivating metals
- identify iron and steel as the main metals used in ships
- identify the composition of steel and explain how the percentage composition of steel can determine its properties
- describe the conditions under which rusting of iron occurs and explain the process of rusting
Students:
- identify data, select equipment, plan and perform a first-hand investigation to compare the rate of corrosion of iron and an identified form of steel
- use available evidence to analyse and explain the conditions under which rusting occurs
- gather and process information from secondary sources to compare the composition, properties and uses of a range of steels
