Lesson summary

In this activity students either work independently or in groups to research the role that oceans have to play in the carbon cycle, and how our oceans might be affected by climate change. Students will draw their own carbon cycle and then revisit the diagram after engaging in several further research activities. Parts of this activity are adapted from:

Learning intentions:

Students will...

  • recognise the role of the oceans in the carbon cycle
  • understand the risks to the oceans from the climate change and the greenhouse effect
  • understand what is meant by the term ‘ocean acidification’
  • recognise the acidification of our oceans as one of the most significant environmental challenges we will have to face
  • recognise that it won’t just be marine species and ecosystems that are impacted; humans will also be affected by ocean acidification.
