LOM v1.0networkedLOM v1.02URLhttp://portal.discoverthecosmos.eu/node/194611enOn Sun’s surface we can see sunspots. What actually are the sunspots? Why are they black? The spots are moving, as the Sun revolves around himself. Can we calculate the rotation period of the Sun? Can we study the topography around the spot? Can we calculate the temperature of the spot peaks? We will try to answer to all these questions, by studying images freely provided by the Astronomical Observatory of Coimbra, the National Schools Observatory and the Faulkes Telescope Project during last month.Sun sunspots rotation period of sun sunspots temperature sunspots topography umbra penumbra.LOM v1.0final1.0LOM v1.0author2013-05-09Hiotelis IoannisLOM v1.0publisher2013-05-09Hiotelis IoannisenLOM v1.0LOM v1.0creator2013-05-09Hiotelis IoannisLOM v1.0validator2013-05-09Hiotelis IoannisLOM v1.0browserLOM v1.0ms-internet explorerLOM v1.0osLOM v1.0ms-windowstext/htmlhttp://portal.discoverthecosmos.eu/node/194611LOM v1.0noLOM v1.0noLOM v1.0activeLOM v1.0very highLOM v1.0mediumLOM v1.0exerciseLOM v1.0simulationLOM v1.0graphLOM v1.0tableLOM v1.0experimentLOM v1.0problem statementLOM v1.0Guided ResearchLOM v1.0Inquiry-Based TeachingLOM v1.0Project-Based LearningLOM v1.0ICT Supported Culture AwarenessLOM v1.0more than 2 didactic hours15-18LOM v1.0DisciplineScienceAstronomy: Solar activityAstronomy: Solar systemAstronomy: Solar system - otherAstronomy: SunAstronomy: Sunspots
