Carbon dioxide levels

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

• Explain why burning a fossil fuel adds carbon dioxide to the atmosphere.
• Recognise that carbon dioxide molecules produced from a combustion reaction may eventually spread throughout Earth’s atmosphere.
• Distinguish chemical and biological processes that remove carbon dioxide from the atmosphere from processes that add carbon dioxide.
• Recognise that increased ocean temperatures may affect the quantity of carbon dioxide that dissolves in the ocean.
• Recognise that changes in the level of carbon dioxide in the atmosphere result from a difference in the rate of addition and removal.

The resources include details of common misconceptions and a summary of the research upon which the resources are based.
