Students become aware of the changes in visibility and sky color due to particles suspended in the air, called aerosols. They observe, document and classify changes in visibility and sky color over several days and understand the relationship... (View More)

This is an activity about changes in the Earth's magnetic field during magnetic storms. Learners will construct a soda bottle magnetometer, collect data, and analyze the results to detect magnetic storm events. The operation of the student-created... (View More)

This is an activity about using spectrogram plots as an indicator of magnetic activity on Earth. Learners will analyze spectrogram data and compare it to local Kp indices in an attempt to determine global magnetic storminess. This activity uses real... (View More)
