The Sun


Basic Level      
  When the indicator is fully coloured, there is a whole set of material specifically developed for that level.
Intermediate Level  
  When the indicator is half coloured, the material from another level is recomended and perfectly suitable for this level. Give it a look!
Advanced Level  
  When the indicator has no color at all, that science case is not recomended for that level.
Super Hero Level  


Although the Sun is an insignificant star in our Galaxy, it is the dominant object in our Solar System and essential for life on Earth. A variation of only a few percent of its energy output would cause disastrous climate changes on Earth. Therefore, it is very important to observe and study the Sun and try to understand how it works. Also we can use the Sun to make measurements in our Solar System or to test Einstein's Relativity Theories. Check this Science Cases that use or study the Sun:


THE VENUS-SUN DISTANCE  NEW VERSION!  (web tools to be updated)
Calculate the Venus-Sun distance using astronomical images from a Venus transit taken by the CESAR team. Students will learn about the movements in the Solar System and use trigonometry and parallax.
Keywords: Sun, SOHO, Transits, CESOSolar System Planets.


SUN'S ROTATION PERIOD   Basic level in 15min!*   
Calculate the Sun's rotation period by tracking sunspotsStudents will understand how the Sun moves and will know how to calculate velocities by tracking targets in time-spaced images.
Keywords: Sun, SOHO, CESO. 


SUN'S DIFFERENTIAL ROTATION  Basic level in 15min!*
Calculate the Sun's differential rotation by tracking sunspots at differnt latitudes. Students will learn about the movement of the Sun and how to calculate velocities by tracking targets in time-spaced images.
Keywords: Sun, SOHO, CESO. 





* Providing students do have the background knowledge.
