Lesson summary
Students investigate the process of ocean acidification, and in particular the role of water temperature in CO2 absorption. They begin the activity by looking at an image describing ocean acidification and responding to associated questions. They are then asked to design an experiment aimed at demonstrating the role of water temperature in CO2 absorption. Students will then summarise their knowledge of ocean acidification in the form or an advertising campaign.
These activities “… are an invaluable tool for teachers to address climate change in an educationally relevant, scientifically sound, and action-based way.” – Tim Flannery (Read more)
Learning intentions:
Students will...
- understand how CO2 is absorbed by sea water
- design and conduct and experiment to demonstrate the role of water temperature in CO2 absorption
- understand the cause and consequences of ocean acidification.
