Weather maps Illustrates the meteorological conditions of an area at a specific time
Shows what the weather is currently doing
Shows what type of weather is expected during the hours and days ahead

How to read a weather map H = high pressure, L = low pressure
Isobars are labeled with a number = air pressure (hectopascals)
Air pressure is higher near the centre of a high pressure weather system
Air pressure is lower near the centre of a low pressure system
Isobars that are closely spaced mean strong winds (low pressure systems)
Isobars that are spaced far apart indicate calm weather (high pressure systems)

Satellite and rain radar images Radar (radio detection and ranging) images:
Predict when and where precipitation will occur
Satellite images:
Predict cloud cover
Show wind speed
Show wind direction

Refer to the images throughout the presentation
Use a recording device to record the presentation which will be played to the class
One of the pair act and the other films for the first half, then swap
