Physicist Helen Czerski explains that hurricanes happen because the Earth is rotating. She shows how, because the Earth is a spinning globe, its atmosphere is controlled by something called the Coriolis Effect. This effect is key to all weather and climate on Earth. Helen goes to Mexico during hurricane season and also demonstrates the Coriolis Effect by throwing a ball on a child’s roundabout. Using graphics and archive she shows how destructive hurricanes can be.

Classroom Ideas

Students can listen to the clip with no pictures. Ask them to sketch out how a hurricane is formed. Then show the full clip and ask them to add labels to their sketches. They could then use craft materials to explain how the Coriolis Effect operates.
