Students will investigate the levels of carbon dioxide in the air from Cape Grim, one of the cleanest sources of air in the world. Using authentic data they will analyse a graph and plot data points on a set of axis. After students have plotted their own graphs they will consider the historic trends and comment on what they think will happen in the future. They will also have the opportunity to investigate another greenhouse gas (GHG) observed at Cape Grim and use this to comment of the levels in more populated areas.
- understand how to read data from a graph
- know how to plot coordinate points onto a Cartesian plane
- discover the impact of air pollution on a global scale and how the levels of greenhouse gas are changing over time
- take personal action to reduce their own greenhouse gas emissions.
