Turn your students into science detectives with this NO PREP, engaging, real-world investigation focused on auroras (Northern and Souther Lights) and space weather. In this case file activity, students analyze solar activity evidence, examine Earth’s magnetic field patterns, evaluate upper atmosphere collisions, investigate aurora color differences, rank possible causes, and build a scientific case to solve the mystery of why northern and southern lights happen.

Instead of passively learning about auroras, students actively investigate, analyze patterns, and reason through the evidence to uncover how charged particles from the Sun, Earth’s magnetic field, and gases in the upper atmosphere work together to create these glowing lights. This activity makes a high-interest space science topic interactive, engaging, and easy to understand while strengthening critical thinking and literacy skills.

✅ NO PREP, no formatting, no issues. Simply download and go. Includes all instructions, answer key, rubric, and background reading students need to solve the case.

10-Part Activity Breakdown

Part 1 – Mission Briefing:
Students are introduced to a case involving bright northern and southern sky lights and the question of what really causes auroras.

Part 2 – Background Reading:
Students build foundational knowledge about charged particles from the Sun, Earth’s magnetic field, the upper atmosphere, and why auroras are usually seen near the poles.

Part 3 – Evidence Log:
Students examine 10 detailed evidence cards related to solar activity, magnetic field guidance, atmospheric collisions, aurora color differences, northern and southern aurora patterns, strong solar storms, satellite observations, and common misconceptions about darkness and cold weather.

Part 4 – Suspect Ranking:
Students rank possible explanations (charged particles from the Sun reach Earth, Earth’s magnetic field guides particles toward the poles, collisions with gases in the upper atmosphere produce light, different gases can glow in different colors, and the incorrect idea that cold weather causes auroras) and justify their reasoning using scientific evidence.

Part 5 – Pathway Tracking:
Students trace how solar activity → changing conditions near Earth → visible aurora display.

Part 6 – Impact Analysis:
Students analyze how solar particles start the aurora process, how Earth’s magnetic field and atmosphere help create visible light, and how auroras help scientists understand space weather.

Part 7 – The Big Question:
Students explain why northern and southern lights happen and how solar particles, magnetic guidance, and atmospheric collisions work together to create auroras.

Part 8 – CER Writing:
Students construct a scientific argument using Claim–Evidence–Reasoning.

Part 9 – Solutions & Action Plan:
Students propose ways to learn more about auroras, model one part of aurora formation, and explain how aurora research helps scientists prepare for space weather.

Part 10 – Reflection:
Students reflect on what surprised them most about auroras and how the investigation changed their understanding of these lights.

What Students Will Learn

• What auroras are
• How charged particles from the Sun help cause auroras
• What role Earth’s magnetic field plays in auroras
• Why auroras are usually seen near the poles
• How collisions in the upper atmosphere produce visible light
• Why auroras can appear in different colors
• How stronger solar storms can make auroras more intense
• Why darkness and cold weather are not the true causes of auroras
• How to use Claim–Evidence–Reasoning (CER) to support scientific explanations
• How auroras help scientists study space weather and Earth-Sun interactions

This activity blends space science, engineering, physical science, critical thinking, and literacy skills into one high-interest, structured lesson that keeps students thinking like real-world scientific investigators.
