34 Scientific literacy should be linked to important elements: an appreciation of the nature of science, personal learning attributes including attitudes and to the development of social values (Holbrook & Rannikmäe, 2007). Relevance of the learning plays an important role for increasing pupils’ scientific literacy. Teaching materials, thus, need to consider a societal frame, introduction of conceptual science on a need to know basis, and embrace the socio-scientific situation that provides the relevance for responsible citizenship (Holbrook & Rannikmäe, 2009). Developing pupils’ responsibility and consciousness is an important factor in the educational environment and by enhancing scientific literacy teachers can have an influence on pupils' actions at the given moment and also in a further future. With better understanding of science and capability to link science to an everyday life and further to the environment in general, a chance for pupils to understand their role in the society and become active participants, have influence on changes and improvements is greatly risen. VISUAL LITERACY Visual literacy is the ability to find meaning in imagery. It involves a set of skills ranging from simple identification--naming what one sees--to complex interpretation on contextual, metaphoric and philosophical levels. Many aspects of cognition are called upon, such as personal association, questioning, speculating, analysing, fact-finding, and categorising. Objective understanding is the premise of much of this literacy, but subjective and affective aspects of knowing are equally important. Visual literacy usually begins to develop as a viewer finds his/her own relative understanding of what s/he confronts, usually based on concrete and circumstantial evidence. It eventually involves considering the intentions of the maker, applying systems for thinking and rethinking one's opinions, and acquiring a body of information to support conclusions and judgments. The expert will also express these understandings in a specialised vocabulary (Yenawine, 1997). An important factor in education is the relevance of specific topics, meaning that learners recognize the relevance of learning those topics for their personal needs or goals. With emphasising relevance, learners’ motivation grows especially intrinsic motivation (Holbrook & Rannikmäe, 2009). As educators, we can achieve the understanding of relevance with techniques such as interdisciplinary approach. With OTA methodology, the interdisciplinary approach is addressed by combining two subjects that are usually taught separately: art and science, specifically art and chemistry, art and mathematics, art and physics. From this point of view, both above mentioned literacies – scientific and visual, are important for
