Detect Solar Storms

In this activity, learners build their own magnetometer using an empty soda bottle, magnets, laser pointer, and household objects. Once built, learners will use their magnetometer to measure slight changes in the Earth's magnetic field due to solar storms, and chart these changes over the course of a few days. Learners can then compare their magnetometer data to current measurements made by NASA scientists. This is an advanced activity that could benefit from the assistance of older learners. Step-by-step instructions are included with photos along with safety recommendations. Activity guide includes a "What's going on?" explanation and connections to relevant science concepts like Earth’s magnetic field, tracking solar storms, and a magnetometer's sensitivity.
