In this project we are going to talk about the rotation of the sun.
It's very important to know some thing, like what the Sun is.
The Sun is a big star of incandescent gases that bring light and heat. We have researched because we went to the ESAC and they proposed a challenge , to know how much it takes the Sun to give a full turn around its own axis.

For this project we have employed different pictures about the Sun spots , the date and the hour in which the image was taken.We did an Excel table in which we put the data that we got from the pictures of the Sun spots and the information that the ESA gave us when we went to visit them. Also we used time measurements, space and speed.
First we calculated the distance that there was in the first picture with respect to the second picture and the next, to know how much it had moved and in how much time. After we added the amounts that we calculated and we measured the time that the Sun took to give a full turn about its own axis. Finally, we doubled the number and we presented the results.
We also found out a few things, such as the hypothesis that is false since the Sun takes more time than believed at first. Because of this, you can find out the rotation of the Sun and more interesting data, and it takes a lot of intelligent team work, because it is an easier work with more people.
Definitely this work is quite interesting and fun. It is also good because you investigate and it is a way to study with classmates. It is more didactic and it may seem easy.
What happens is that the speed is increasing and later decreasing as time passes by. After doing this research , we have discovered that the speed of rotation of the Sun varies according to the position in which it is and the movement of spots. We have also collaborated in a project with ESAC , and thus we have learned much with the investigation.
