Scientific weekend

The Scientific weekend, which was hold on 26 and 27 May at MUNCYT in Alcobendas, featured the participation of Stars4all


The 8th edition of the scientific weekend (Finde Cientítico) was organized by the Fundación Española para la Ciencia y la Tecnología (FECYT) and the Museo Nacional de Ciencia y Tecnología (MUNCYT) during the last weekend of May, and opened its doors by fourth year in a row to bring Science and Technology to all audiences.

The entrance to the Finde Científico, whose organization has the support and collaboration of Obra Social “La Caixa”, was free and the event was attended by more than 40 institutions from all over Spain, including colleges, schools, museums, universities and research centers, such as MUNCYT, the Consejo Superior de Investigaciones Científicas (CSIC), the Museo Nacional de Ciencias Naturales (MNCN), the Universidad Autónoma of Madrid, the Museo Geominero, the Universidad Politécnica of Madrid and the Centro de Astrobiología or the Universidad Carlos III.

As a whole, and with all the institutions, those attending the Finde Científico could participate in more than 200 workshops, experiments and games including those from the citizens science project Stars4all -thanks to the Universidad Politécnica of Madrid and Universidad Complutense de Madrid- for explaining to young and not so young people what is Light Pollution through various activities designed for all ages.

Based on the activity from the NOAO QLT kit “Light Pollution and Light Trespass” we designed a city model with different shapes and types of working lampposts. Participants could explore different lighting possibilities regarding light color and orientation as well as learning streetlights shining windows at night should be avoid.




Light is composed by different colors and different bulbs emit different energy. Blue light is more energetic than orange one and affects your body’s ability to produce melatonin, a very important hormone that helps you sleep at night. You can make your own DIY spectroscope using cardboard and a piece of CD to see de differences between led and fluorescent bulbs. You can download the template and the instructions to do it at home.




Cities at Night project was also presented. 54 cities from all over the world were printed on magnetic cards and participants had to find them lost in the poster. After finding them all they would compare the lighting as seen from space of 6 european capitals and how Madrid looks like from the International Space Station.




A big black curtain covered a corner of the stand. Inside, kids could see the stars thanks to a “Star theatre proyector” and perform the NOAO QLT kit activity “Light Pollution and Night Sky” to determine how different kinds of lights and shields affect the number of stars that can be seen. Participants could try different lights and shields to see the effects on the night sky.




All the participants were invited to play to our games. The apps Night Knights and Cazasteroides were the option for the ones who had their phones with them while the youngest draw their experience on our stand.
