2. 2Starter questionsWhat different forms of carbon have you heard of before? Define the words ‘respiration’ and ‘photosynthesis’.What role does carbon dioxide play in our atmosphere?C612
3. 3The carbon cycleYou will pretend to be a carbon atom moving through the carbon cycle.There are five stations around the room: FOSSIL FUELSTHE ATMOSPHEREA PLANTANIMALSTHE SEA
4. 4The carbon cycleAt each station you must flip two coins.Then follow the instructions depending on what combination of heads (H) or tails (T) you get:HH = 2 heads TT = 2 tails HT = 1 heads/1 tailsTake your carbon cycle passport with you and record your journey!
5. 5Make your own diagramNow use the notes of your travels from your passport to produce a diagram of the carbon cycle.Make sure to mark the different stations you travelled to and how you got there.
6. 6DiscussionWhich stage did you go to most often?Who was ‘locked up’? What were the carbon reservoirs?How many times did you enter the atmosphere? How many processes led to the atmosphere, and how many led away from it?Which processes are natural? Which are human-led?What was the approximate timescale of each process?
