Northern Lights

Brilliant ribbons of green, purple, and red dancing across the night sky aren’t just beautiful-they’re powered by the Sun. This engaging reading passage explains how auroras form high in Earth’s thermosphere when charged particles from the Sun collide with gases in the atmosphere. Students learn why these colorful displays appear mostly near the North and South Poles, how different gases create different colors, and why scientists study auroras to better understand space weather.

As students read, they build informational reading skills by identifying sequences, recognizing cause-and-effect relationships, and connecting scientific ideas across multiple paragraphs. Vocabulary such as aurora, thermosphere, solar wind, charged particles, oxygen, and nitrogen is introduced naturally throughout the passage. The warm, conversational style turns one of nature’s most spectacular light shows into an exciting science lesson.
