Tracking Sunspots

This lesson plan, adapted from NASA's Solar and Heliocentric Observatory website, teaches students how to examine and track sunspots at different latitudes on the sun.  This activity "can be used as an introduction to the solar cycle to explore the relationship between sunspots and other solar activity."  This webpage includes downloads to PDF downloads of both the lesson plan and the associated activity worksheet and the associated standards that it fulfills.  The lesson plan is intended for students in middle school and higher; it takes one class period to complete the lesson.
