back burning:starting small fires in front of the firefront to reduce the amount of fuel available and slow the progress of a fire.
bushfire: fire burning out of control in the open; also called a wildfire
climate change: a current warming trend of the Earth’s atmosphere.
drought: a period of below average precipitation
El Niño event: the reversal (every few years) of the more usual direction of winds and surface currents across the Pacific Ocean. This change causes drought in Australia

fire front: the edge of the fire that spreads at the fastest rate
firebrand: aerial burning fuel that blows ahead of the fire front
firestorm: an intense fire, which may generate strong convection currents and violent winds that cause long range spotting and flame spirals
fuel: any material that burns
hazard reduction burn: a way of preparing for bushfires by starting a controlled fire in a cool period before fire season. This reduced the fuel in the area.
heatwave: a short period (usually a few days) of well above average temperatures
La Niña event: a period of well above average rainfall in eastern Australia, which often brings floods

Each student receives a copy of the glossary terms and a single glossary bingo card (each card contains random 9lossary terms). As a class, read through the glossary terms. Students are then given 5 minutes to revise the terms and definitions. The teacher reads out definitions in a random order. When the student hears a definition of a word on their bingo card they highlight it. When students have a row of three terms they call out “Bingo”. An example of a bingo card can be seen below, but the downloadable file below contains multiple variations.
