The reason why we are doing this investigation because our school is working in a scientific proyect called GIO (Get in to orbit).
In the proyect we are about the universe for this we dis an excursion to the ESA , we are sowing the link:

In the excursion that we do to the ESA they proposed resolve a problem very interesting, is about the rotation of the sun.
Is importan because the sun travel for a velocity more slow.
The materials that we have used have been photographs of the movement of sunspots (4 images of different days and times), scientific tables with calculations made by us, we also use an excel file where we complete a table with distance data that.We calculate from the spots of the different images previously proposed. The magnitudes we used were cm and time, plus we found the speed of the spots. The procedure was to measure the distance of the sunspots in cm and pass them km, do the calculations, find out the time and draw a conclusion, all this based on tables.
The hypothesis that we made at the beginning of the research, did not come to the results we obtained at the end. Our hypothesis resulted in sunspots taking a month to complete a round the sun but the final result was 16 days and 4 hours approximately.
It has been interesting because is importan to get to know things conected to sun because thanks to the sun we live in the world with room temperature to have a stable al though over the years temperatures have been riding in summer and winter.It is colder because of air polluntion,forets forestion and because more species of animals are in danger of extintion and little by little they are creating more support campaings to improve the world. The magnitude used were centimetgres passed to kilometres and thanks to calculate the speed of the sunspots.
