There exists a large number of studies about non-formal education in education, less about chemistry (but see, e.g, [1]), and a few or none related to off-shore chemistry. This had been identified by several authors. In this article we present an approach to education based on guided inquiry of the observation of materials and processes traditional and industrial that can be seen outside laboratories and classes, giving the specif exampled of marine and offshore chemistry, aquaculture, and consumer products. This inquiry can be stimulated and conducted by specific internet sites like Percursos Quimicos [2] and others, mobile phone applications, leaflets, or specif kits, and others. Pupils can bring to the classes their observations and questions and the teacher can suggest also other observations, following the official programs of teaching. This methodology is especially interesting when pupils are not in school due to pandemics or other reasons.
