Studying climate change
I can understand how Earth's polar ice caps are changing.
Lesson details
Key learning points
- By analysing how the northern polar ice caps have changed, predictions can be made
- By analysing how the southern polar ice caps have changed, predictions can be made
Keywords
Forecast - A forecast is a prediction of a future event occurring (based on data).
Extrapolation - Extrapolation is the process of estimating unknown values that are outside the range of existing data.
Common misconception
When comparing the modal class for two datasets, pupils may think that the dataset with the greatest modal class is the one which has the greatest frequency for its modal class
Use the frequency to identify the modal class for each dataset, but then compare the values within each class to determine which dataset has the greatest modal class.
This lesson uses types of statistical graphs which pupils may not have previous encountered. However, pupils do not need a detailed understanding of these graphs to solve the problems in this lesson. Problems request only general conclusions about the data based on its shape or basic comparisons.
