This lesson presents an overview of phenomena related to the magnetism of the Sun, in particular to sunspots and their 11-year cycle, solar flares and magnetic disturbances on Earth caused by solar activity. It also reviews briefly the connection between electricity and magnetism. Students will learn facts about the discovery of sunspots, their intense magnetism, and their 11-year cycle. They will be introduced to solar activity associated with sunspots and their cycles, e.g. the abrupt brightenings known as solar flares. They also learn that solar activity is probably associated with the release of magnetic energy, and that such releases can propel fast plasma flows towards Earth, causing magnetic storms.
