We collect an experience made by the CEIP Tomás y Valiente, of Velilla de San Antonio, which took place last year 2017-2018, on April 8, and in which we wanted to share what lived with all the countries that are part of the Erasmus + ' Art for Coexistence ' project , of which the FYME is part. It was about opening the educational center to NGOs and entities working together from the CEIP Tomás y Valiente and doing it with the students themselves as protagonists, linking the whole community to work for the principle of the defense to the Earth. So it articulated an educational activity based on a meeting of delegates to organize a composting workshop with the purpose of making compost during the course in charge of all the boys and girls of the school.
Composting Workshop
And what better way to understand what was done to give voice to the center itself so that we narre what lived in that day of last April:-On the 8th there was a meeting of delegates, we met in the library and there was waiting for us Diana , a girl who belongs to the NGO ' Friends of the Earth ' who came to teach us something. First he asked us to help to mount a box that was dismantled on the floor, it was like riding a puzzle. It took a while to get it, it was not easy to fit the pieces. 
He then asked us to thought for what that box could serve and each of the delegates went on to say what we thought. We all agreed that the box would serve to store things, even one of the little ones said it would serve to get him inside! Others thought it seemed like it would serve to throw in garbage. So little by little, talking with Diana we knew that the box we had assembled is called composter and is used to make compost none knew what was the compost and we had not seen, so Diana showed us a full boat that turned out to be dark Earth , clean it smelled just to ground. Finally he explained how to get it:
- First we had to take the composter to a place where it had contact with the ground, because the bottom of the box was not closed.
- Then we would have to fill it with organic residues that are remnants of vegetables that were alive (fruits such as apples, pears, bananas, leaves of trees and shrubs and small pieces of wood). You can not take fruits, but their remains, skins, shells and the inner part that we do not eat and we call heart.
- Diana explained to us that to convert these organic wastes into COMPOST we have the help of some animals that live inside the earth and that are the worms and the balls or cochineal bugs. That's why the part of the box that is in contact with the ground has no lid, it is open to leave the ground and go out to eat what we put in the compost.
- After eating the residues, the worms and the Insects excrete, (as one of the delegates said they do "poop"), and so the compost is gradually formed.
- To make it go well it is necessary that the composter is protected from the sun, and the wind and also needs air, so the box has holes.
- We install the compost in the garden and fill it. First with remains of leaves and branches, then residues of cooking in the dining room (leeks, lettuces, etc…) and peelings, hearts and shells of apple and plantain that some professors brought.
Also, at this point, Diana told us that we had to be very careful with several things:
- One: The pieces we throw into the compost have to be small. We have to cut them before putting them in the container that is going to be in the entrance of the garden, there we will put the fruit residues of our breakfasts.
- Two: We should not throw the container or the remains of oranges or mandarins because they do not like worms or ball bugs and if they do not eat it is not made compost.
- Three: Empty the waste container in the composter, once or twice a week and remove it well with a remover that has left us. This is so that the new waste will go to the bottom and so do not come the flies to eat them and are the worms, which are on earth, those that do.
- Four: She will come to see if we are doing well and if so in the month of June and have a compost bues that we use to fertilize the plants in our garden.
- Five: All classes will remove and empty the waste container in the composter by rotating shifts so that we are all responsible for achieving it.
