LO: to know what the ozone layer is

 What are these pictures showing?

 What is this picture showing?

  The Earth is surrounded by a deep layer of gas called the atmosphere (a mixture of gases, including nitrogen, oxygen, argon and carbon dioxide)  Oxygen in the atmosphere can change its physical state from O 2 to O 3 which is known as ozone  Ozone plays some very important roles in protecting us… What is the ozone layer?

 Protection  The ozone layer protects us from harmful rays emitted by the sun  Ultra-violet light (UV) can cause both skin cancer and damage to the eyes, such as cataracts (this is where the lens does not allow light to pass through easily, blurring vision)

 Damage  In the past century we have been rather good at damaging the ozone layer…  This has been via the use of chlorofluorocarbons (CFCs), e.g. fly spray; refrigerator coolants; aerosol sprays – the chlorine reacts with O 3 and breaks it down High flying jet aircraft exhaust gases also react with the ozone: Concorde was especially bad for this

 Ozone damage  Why are people in Australia at higher risk of skin cancer?

 Effects of Ozone loss on skin cancer rates % ozone layer lost% increase of skin cancer Plot a graph to display the data opposite. What type of graph should it be? Remember the key features that make a good graph

 ✓ X-Axis correctly scaled, labeled and unit included ✓ y-Axis correctly scaled, labeled and unit included ✓ Correctly plotted points ✓ Correct line of best fit (title) Marking your graph
