Using a set of activities, recommendations, and diagrams, participants will construct a fully functional Space Weather Action Center (SWAC) for use in a classroom. Students will access, analyze, and record NASA satellite and observatory data to... (View More) monitor the progress of an entire solar storm. Afterward, they will transform the data collected in their student journals into real SWAC news reports using an adaptable SWAC script. (View Less)

This is an activity about the declining strength of Earth's magnetic field. Learners will review a graph of magnetic field intensity and calculate the amount by which the field has changed its intensity in the last century, the rate of change of its... (View More) intensity, and when the field should decrease to zero strength at the current rate of change. Learners will also use evidence from relevant sources to create a conjecture on the effects on Earth of a vanished magnetic field. Access to information sources about Earth's magnetic field strength is needed for this activity. This is Activity 7 in the Exploring Magnetism on Earth teachers guide. (View Less)
