In Social Studies we have been learning about the provinces and territories of Canada. We also learned that many people visit the Yukon, Northwest Territories and Nunavut to see the Northern Lights or Aurora Borealis. During a class discussion, Matthew asked an interesting question. He said ‘What causes the Northern Lights?’. Below is a video from the University of Oslo that does a very good job of explaining what causes this natural light display. In the southern hemisphere the lights are called the Aurora Australis.
