Quick Summary: Using authentic data students will demonstrate their knowledge of mean, median and range to describe and compare yearly data trends. Using their calculations students will describe historic trends, predict what will happen in the future and what the changes might be if we were able to switch from using fossil fuels to sustainable energy sources.
- Students understand how to calculate mean, median and range.
- Students know how to interpret these statistical values in the context of their data.
- Students discover the how the levels of greenhouse gas (GHG); particularly carbon dioxide, are changing over time and what the future holds for these levels
- Students take personal action to reduce their own greenhouse gas emissions.
General capabilities: Numeracy, Critical and creative thinking.
