In the early days...

AJC was born unusually: first we created the scientific meetings and only then the association appeared as an organizing commitee. This is quite an interesting history. The year was 1982 when a group of youngsters attended the 24th LIYSF (London International Youth Science Fortnight) on a trip sponsored by Calouste Gulbenkian Foundation. Inspired by the experience, this youngsters decided to do a similar event in Portugal. In September of 1983 it was born in Lisbon the first Youth Science Meeting, by the portuguese name "Encontro Juvenil de Ciência (EJC)".

The first EJC was quite remarcable with an attendance of around 100 participants. Followed by this one, it came two more editions in the biggest universitary portuguese cities, Oporto and Coimbra.

The EJC's organizing group stated a great potencial coming from the participants in order to promote future events. To include them, it was born the "Projeto Encontro Juvenil de Ciência (PEJC)", a wider project that lasted the entire year from where new activities and small projects around the country started being developed. This was the first step towards a national board.

In November 1986, during the PEJC General Anual Meeting, it was changed the name to "AJC - Associação Juvenil de Ciência". Officially, the papers where signed on March 16th, 1987.


Even though AJC was only born in 1987, the first YSM happened in 1983. This meeting was reserved mostly to national participants and more recently open to portuguese-speaking countries such as Brazil, and to other latin countries like Spain. Until this moment, the meeting was called Encontro Juvenil de Ciência (EJC).

Back in 2014 we created history once more. We opened our doors internationally and now we welcome participants from all over the world. So far we received registrations from the biggest part of European countries, Asia, Africa and Latin America. From that moment on, EJC was renamed to its English designation as Youth Science Meeting (YSM).

Our Values

AJC is the name of the structure that EJC youngsters found out as the one that could represent the legacy left with the aim of being improved.

AJC is not an office, a computer, a bill or a legalized statute. AJC is the will of many "EJC youngsters" to keep being so.

AJC is the ability of promoting scientific activities oriented by youngsters and developed for youngsters interested on them.

AJC borns in every EJC/YSM that ends and reborns in every scientific activity that is organized by its associates and members.

Today AJC keeps its major role promoting science, always having in mind our foundation values. It is an association managed by youngsters and whose activities are aimed to youngsters from 15 to 25 years old.

AJC also created working groups specialized in several scientific areas. One of the oldest groups is GTA (Grupo de Técnicas Aerospaciais/Aerospacial Techniques Group) that goes to schools teaching the phisics and mathematics behind the building of a rocket, among other scientific areas that contribute to do so.

Years and years have passed since our foundation and today we count with more than 1800 associates. Also, AJC entered in the social networks and now we count with thousands of followers on Facebook, Twitter, Instagram and Youtube.
