1. Pre-Starter
Complete your red, amber or green starter activity in your book. Remember which task you are doing depends on how you did on this topic in your baseline test. 5

2. Global atmospheric circulation
Red - To be able to define what atmospheric circulation is and describe surface wind and pressure belt patterns.
Amber - To be able to explain how the atmospheric circulation model drives the world’s weather.
Green - To be able to compare different weather and climate patterns in different global regions and explain their variation due to global atmospheric circulation.

3. Starter - Context In pairs, think about:
Where would you have rather been yesterday?
What causes 3 different places to have entirely different temperatures and weather on the same day?

4. 3 Global atmospheric circulation - Core basics Global - The earth
Atmosphere - The air above our heads - mass of swirling gases, liquids and solids such as carbon dioxide and oxygen, water vapour and droplets and ash.
Circulation - Circular air movements called cells. These cells all join together to form the overall circulation of the earths atmosphere.
Task (All) - Write your own definition for ‘Global atmospheric circulation’ in no more than 20 words. 3

5. High pressure = Air that is sinking towards the ground
The Earth's atmosphere exerts a pressure on the surface. Pressure is measured in hectoPascals (hPa), also called millibars.
High pressure = Air that is sinking towards the ground
Low pressure = Air that is rising from the grounds surface

Task 1 - RAG
Using the diagram and information, complete the quick question task (RAG)
By the end of this task you should be able to:
Say what the diagram shows.
Explain what patterns are shown.

7. 60 second challenge - Peer teach

8. Task 2 - RAG - exam application
Explain how the global atmospheric system affects the weather and climate of the UK using key terminology. (6 marks)
Explain how the global atmospheric system affects the weather and climate of the UK giving evidence from the climate graph and using key terminology. (6 marks)
Compare the weather and climate of hot deserts and equatorial areas. Explain how the atmospheric circulation system affects these climates, giving evidence from the climate graphs. (8 marks) 15

9. Compare your exam answer with a model
How does your response compare?
What can you add or do differently? 10
Improvement options :
Add to/re-write your exam answer using the model.
Write instructions for somebody to use if they were to complete your question. Do this as a step- by-step guide including what improvements you would need to make.
Choose the next up question if you are happy with your first response.

10. Plenary
