1. Starter:
How does the water and carbon cycle differ between the Tropical Rainforest and the Arctic Tundra?

2. How do the stores and flows of the water and carbon vary between the Tropical Rainforest and the Arctic Tundra
In groups, on an A3 sheet, you need to show how the above differ. You will need to draw two carbon cycles and two water cycles.
You can use highlighters, symbols, width of arrows/boxes to show difference in the amount/size of flows and stores in each location.

3. You can join up the above questions.
How do the stores and flows of the water and carbon vary between the Tropical Rainforest and the Arctic Tundra
Using your A3 sheet and your notes, answer the following:
1) How do the following differ between the Tropical Rainforest and the Arctic Tundra and why?
a) The distribution of carbon
b) The flows of carbon
c) The distribution of water
d) The flows of water.
You can join up the above questions.

4. Plenary: Exam question
“Human factors affect the water cycle more significantly in the Tropical Rainforest than in the Arctic Tundra”. Discuss.

5. Other past questions from specimen papers for living world
'The damaging impacts of human activity on the carbon cycles is of greater significance than the water cycle.' Discuss. (16 marks)
With reference to a case study of the TRF examine the significance of the forest trees in the carbon cycle.
Examine the significance of the role of vegetation in linking the water and carbon cycles. (10)
