Learning Activities for Outcome 1

The corrosion of metals

CORROSION is the gradual destruction of metal by the effect of water, chemicals etc.

TarnishRust

Tarnishing is a form of corrosion. 

The metal becomes dull and loses its colour.

Rusting is a form of corrosion that affects only iron and steel.

Demonstration – Investigating the rusting of iron

Look at the information given. What causes the iron nail to rust?

Explain/justify your answer.

Both air and water are needed for iron to rust.

Rusting is an oxidation reaction.

The iron reacts with water and oxygen to form hydrated iron(III) oxide, which we see as rust.

iron + water + oxygen    →    hydrated iron(III) oxide

Rusting of iron

Note: You don’t need to know the symbol equation – it’s rather complicated!

Learning Activities for Outcome 2

Research Task 1 - Comparing the properties of aluminium and iron

Aluminium and iron are typical metals with many uses.

1. What properties do they have in common?

2. Below are some of the properties by which they differ.

For each property describe their differences and suggest whether these differences are an advantage or disadvantage. Give an example of a common use for each advantage.

• Corrosion resistance

• Density

• Magnetic

• Cost

Research Task 2b – Recycling of metals and cars

Every year in Europe, end of life vehicles generate between 8 and 9 million tonnes of waste.

A European Directive requires car manufacturers to improve their designs to make cars easier to recycle.

Look at your list of materials from Task 2a.

Find out how recyclable they are. You should include:

• Ease of separation.

• Ease of purification.

• Cost in ££.

• Cost in energy.

• Environmental impact.

Review

• Swap books with the person next to you and look over their work. Write a WWW and EBI statement.

• Stand up if you have developed some skills this lesson? What are they?

• Tell the person next to you three things you have learnt this lesson.

• Did you successfully complete tasks at your target grade?

• If not, what do you need to do next in order to meet your target grade? Record this in your diary to be done as part of your extended learning at home.

• Is there any part of the lesson you think you need to go over again next lesson?

• How will you remember what you have learned today for your exam?
