How many stars can you see from your house?

We are learning about the atmosphere in class. As you can read in our book, air pollution is the presence of various substances or types of energy in the atmosphere in quantities that are harmful to living beings and the environment. Gases, solid particles.... perhaps these are the most known pollutants. But there are more. Noise, for example, is a type of energy that causes important effects on living beings. And light? Can light pollute our cities?
In my opinion we are lucky because some of you live in the city and some in villages surrounding Granada. I want to propose you an experiment. I want you to look at the sky at night. Take a sheet of paper and cut a frame of 3 cm each side. Through this window look at the sky to the area with the highest number of stars. Count them!!! We will discuse your results in the classroom.
Please, write comments with your conclusions!!

    La contaminacion luminica es muy importante.Contra mas alto estes se ven las estrellas y cuando estes mas bajo no se ven las estrellas. En algunos casos pueden haber nuves, los remedios son: Que hagan farolas menos altas y con un interuptor

  2. I think that the light pollution prevent us from seeing the stars which is sad because we can’t enjoy the incredible night sky. In addition, this tipe of pollution become a problem for plants and animals that change their normal habits of life such as sleep schedules. The solution can be to reduce the number of streelights in the city or minimize the amount of light emitted by them.

  4. About the light pollution there is in Granada a 3% , a 14% in Cenes 31% in Güejar Sierra. You can see more or less depends on the light pollution that there is in each place.

  6. Hemos hecho un trabajo que consistía en hacer un marco de 2cm de ancho y teníamos que ponerlo en la ventana el marco y haber cuantas estrellas veíamos. Yo creo que hay mucha contaminación lumínica,la mitad de la clase no ha visto tantas estrellas como se deberían haber visto, yo lo que haría seria los paneles solares que hay por la noche,las farolas...seria que pondría bombillas de bajo consumo.Le pregunte a mi madre que ella que haría y me ha dicho que ella no sabe lo que es eso

    Mi conclusión que yo tomo es que deberían poner menos farolas y menos luces y carteles luminosos porque si no no se ven bien las estrellas.

    I think there is a lot of light pollution because with the beautiful sky we have in this world, it does not let us see the stars clearly. It is because there are many streetlights, solar panels ... etc. In Granada there are 3% of stars, in Cenes there is 14% of stars and in Dudar and Guëjar there is 31% of stars.
