The CIIMAR – Interdisciplinary Centre of Marine and Environmental Research – is a research and advanced training institution of the University of Porto. Its mission is to develop high-quality research, promote technological development and support public policies in the area of Marine and Environmental Sciences. Through the integration of different disciplines, the centre aims to contribute to the understanding of the biological, physical and chemical processes which occur in the ocean and the coastal zones, for the sustainable use of aquatic resources and the evaluation of the impact of human activities on ecosystems. CIIMAR runs an extensive outreach program addressed to foster the dialogue between scientists and society, to improve the public knowledge and the perception of science and to increase the interest of the young students towards scientific careers.CIIMAR manages two Centres for Environmental Interpretation and Monitoring (CMIAs) through agreements with the City Councils of Vila do Conde and Matosinhos. Outreach activities includes temporary exhibitions, seminars, workshops performed regular in house and field trips for public of different ages.“The CIIMAR in School” is an outreach project developed in partnership with the CMIAs of Vila do Conde and Matosinhos designed for students and teachers from the basic to the secondary education. The project seeks to awaken the curiosity of the youngest about the Marine and Environmental Sciences. The project consists of a free web-based platform containing a set of experimental protocols developed and tested by CIIMAR researchers in the laboratory, liable to be carried out by the teachers in the classroom. In addition, the portal offers a range of free lectures that may be requested by the schools. These lectures will be held in the classroom by CIIMAR researchers and will address various themes within the Marine and Environmental Sciences related to the CIIMAR research areas.
