This powerpoint presentation covers Topic 5.2 (Greenhouse Effect) in the IB Biology curriculum. Each slide is labelled with the specific learning objective and animation/video links are provided in the slide notes.
The slides are formatted to print well for handouts or revision and I can provide a pdf version upon request.
As always, please let me know if you have any suggestions for improvements. These are always a work in progress!
**IB Biology Learning Objectives
5.2.1 – Draw and label a diagram of the carbon cycle to show the processes involved.
5.2.2 – Analyze the changes in concentration of atmospheric carbon dioxide using historical records.
5.2.3 – Explain the relationship between rises in concentration of atmospheric carbon dioxide, methane and oxides of nitrogen and the enhanced greenhouse effect.
5.2.4 – Outline the precautionary principle.
5.2.5 – Evaluate the precautionary principle as a justification for strong action in response to threats posed by the enhanced greenhouse effect.
5.2.6 – Outline the consequences of a global temperature rise on arctic ecosystems.
