2. Objectives Construct the carbon cycle identifying different processes which occur. Outcomes 3: Describe different processes within the carbon cycle. 5: Explain the role of different processes in the carbon cycle. 7: Evaluate how the positions and quantities within the carbon cycle can be shifted by human activity. Key terms: carbon, decay, fossil fuels, combustion, respiration, photosynthesis

3. Task Using the information you have been provided with I want you to construct your own carbon cycle. The following should be identified: Processes and reactions Organisms involved where relevant Place where processes are occurring (Spec part 4.3 will help you with constructing this) Outcomes 3: Describe different processes within the carbon cycle. 5: Explain the role of different processes in the carbon cycle. 7: Evaluate how the positions and quantities within the carbon cycle can be shifted by human activity. Key terms: carbon, decay, fossil fuels, combustion, respiration, photosynthesis

4. Self review Does your cycle cover each of the following points? Key terms: carbon, decay, fossil fuels, combustion, respiration, photosynthesis

5. Questions 1.What is carbon flux? 2.How can carbon flux be represented? 3.Describe the data shown in the graph. 4.Explain the reasoning behind the trends seen in the graph. Key terms: carbon, decay, fossil fuels, combustion, respiration, photosynthesis

6. Home learning Answer the exam style questions on the carbon cycle. Key terms: carbon, decay, fossil fuels, combustion, respiration, photosynthesis Outcomes 3: Describe different processes within the carbon cycle. 5: Explain the role of different processes in the carbon cycle. 7: Evaluate how the positions and quantities within the carbon cycle can be shifted by human activity.
