This week's Planet Earth focus is Extreme Weather: Storms, Hurricanes and Tornadoes
A normal storm is where there is heavy rain and strong winds. What changes a normal storm into a thunderstorm is the presence of thunder and lightning.
Can you find out why we see lightning before we hear thunder?
Read through the PowerPoint and then try the activity below:
Activity: Name That Storm
Do you know how storms get their names? Find out and have a go at the following activity:
Present your new knowledge about hurricanes and tornadoes
Imagine that you are a major television reporter for BBC news and you have a 60-second live update slot later today. You need to update people on the weather and what to expect in the next few hours. Will there be storm surge? What should people do? How can they prepare? You could film your bulletin on a phone or iPad and stand under an umbrella for effect. You could even ask someone to pour water over the umbrella whilst they're filming you!
Create a fact file, poster, leaflet, booklet, PowerPoint, sculpture or piece of art which presents an example of extreme weather and the destruction it can cause. You could choose tornadoes, hurricanes or storms and how you organise this is entirely up to you.
Imagine you are working for the local weather office in an area where a tornado or hurricane is expected to happen. Can you create a poster/leaflet to help local people understand what they can do to stay safe and minimise damage?
Try to include the following:
Now put all of your new knowledge to the test:
