Fibonacci and golden ratio in interdisciplinary teaching

Golden ratio and Fibonacci numbers appear oft en in nature. It is known in Mathematics that any potential of the golden number fi (φ) we can get by addition of the two previous potentials. In biology, for example, it is seen in organism growth, as well as adding a number to of units into the existing population. Sequences of numbers known as Fibonacci's serial can be recognized in many creations in nature, and very oft en among living organism and natural occurrences, there are patterns of three, five or even eight golden spirals. The topic of golden ratio is very appropriate as the model for achieving interdisciplinary segments in teaching. Interdisciplinary teaching opens possibilities towards widening teachers' competencies and contributes to exchanging ideas and experience. Nevertheless, in recent time, it has been insisted on this way of work at schools, teachers are reluctant to realize this kind of taching in practice, because of organisation and the number of classes. Taking into account problems, which teachers face, thematic interdisciplinary seminar Spirals and rabbits has been organised at the Faculty of Biology, aimed primarily at primary school teachers. According to attitudes of the participants, application of Fibonacci's arrays, by their simplicity and being so obvious, can contribute to raising students' interest for school curriculum, and it is a good way of connecting knowledge from different subject and popularization of science in general.
