The Northern Lights - level 1
There are explosions on the sun. These explosions send particles into space. These particles move towards the earth.
The particles enter the atmosphere. They hit the air. When they hit the air, they make light. These lights are the Northern Lights.
You can see the Northern Lights in Scandinavia, Greenland, Alaska, Canada and Russia. Sometimes, you can see them in other places, too. People in Minnesota can see them.
Difficult words: particle (a very small piece of something), earth (our planet), atmosphere (all of the air around the Earth).
