The Sun

 

Basic Level      
  When the indicator is fully coloured, there is material specifically developed for that level.
Intermediate Level  
  When the indicator is half-coloured, the material from another level may be appropriated for this level. Give it a look!
Advanced Level  
  When the indicator has no colour at all, the Science Case is not recomended for that level.
Super Hero Level  
     

 

Although the Sun is an ordinary 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 to understand as much as possible how it works. Moreover, we can use the Sun learn more about our Solar System, and to test some physical theories, such as Einstein's Theory of Relativity.
