In this activity, students will explore the concept of fire danger rating (FDR) and its classifications, along with the forest fire danger index. They'll analyse historical changes in fire weather conditions, interpret maps and statistics, and make informed decisions based on graphical and statistical data, enhancing their understanding of the relationship between fire and climate.

Step by step guide
Step 1: Introduce Fire Danger Rating
Introduce the concept of Fire Danger Rating (FDR) and describe how it is used by firefighters and to warn the community of bad fire days. Introduce classification of FDR.
Introduce the forest fire danger index and discuss how it is calculated and how it is used in scientific studies.
Step 2: Students undertake mathematical problems
Students will undertake mathetmaical problems from the handout that include:
Interpreting maps/statistics about changes in fire weather and fire danger rating.
Examining the research output from an example that considers historical changes in fire weather conditions in Australia.
Considering the different ways of condensing and interpreting data.
Interpreting graphical/statistical output relating to changes in space and time.
Making decisions based on graphical/statistical output.
