At 9 in the morning we begin our activities in the hall offered by the Local Council of Alcalá de Henares. We begin with the theme of light, topic of this meeting. The first is an explanation of a brief history of the scientific understanding of light, followed by an explanation of art and light and light and mathematics. Next we carry out an activity with a pinehole camera and doing calculations with Thales's theorem. We managed to measure a real tree thanks to the image formed in the pinehole camera. Meanwhile, the teachers held a coordination meeting.

Afterwards, we return to the school to work in the computer room on the subject of Jean Laurent photography and visit the museum about this artist, which is part of the school.

We have lunch in a restaurant near the school and in the afternoon we return for our last activity of the day, a scientific escape room on the theme of light. In it we carry out experiments to recover "stolen light".

On Thursday all the Erasmus+ partners met in the morning and set off to Toledo. Our first stop was to take a group photo with the stunning view of the ancient city of Toledo. Then, after reaching the city center, the students were divided into their groups and started a photo contest. They had to take photos of the most important monuments in the square market in Toledo. The winners were the students who managed to find all the marked attractions and take a photo of them. During that contest time, the teachers were also involved in visiting the city. They were visiting The Primatial Cathedral of Saint Mary built in Gothic style, with a ceiling fresco made by Luca Giordano. The light coming into the Cathedral makes an impression that it comes directly from Heaven. Also, the light changes during the day so different parts of the Cathedral are lit and the perception is different. They could also observe the influence of light on the El Greco painting “The Disrobing of Christ” which is astonishing and reveals the power of Greco´s colors in connecting the human world with heaven. They also managed to visit the Councils and Visigoth Culture Museum where they were able to admire reliefs, epigraphic objects, paintings, historical documents and gold work and trousseau from the cemetery of Carpio de Tajo. After eating packed lunch all the group went to Church of Saint Thomas to see one of the El Greco masterpieces: “The burial of the Count of Orgaz” which depicts the local legend in which the Saints Augustine and Stephen descend from heaven to bury the Count of Orgaz. The last point of the day was the visit at the Museum of El Greco which consists of two buildings, a 16th-century house with a courtyard and an early 20th century building forming the museum, together with a garden. The house recreates the home of El Greco, which no longer exists. 

After coming back to Alcala, the students had time to meet and integrate in international groups and teachers went to have dinner at La Seda restaurant where they could taste some typical, Spanish dishes.

On Friday all the partners met at school to continue their working activities.

Students were divided in five groups and dealt with Dissemination materials in different formats of the topics worked on during the previous activities, realizing some products.

Teachers met to talk about the Dissemination activity in their schools and agreed that in each school they would organize an exhibition at the end of May throughout all June, inviting the whole local community: local, nearby schools,  local authorities, families and students to visit the exhibition. The students involved in the project should show all what they have done during these three years of work.

In the afternoon, the participation certificates were distributed in an emotional ceremony. Next, the students and teachers enjoyed the farewell party for the meeting, hoping to meet again in the future.
