The spiral shape in nature and its relationship to the Fibonacci sequence and the golden ratio as an input to the teaching of the Metal artifact

Summary
Nature in its various forms raises the eye of the artist who translates nature in the form of works of art. Art is a basic need for man as his biological need, so the artist learned to respect the instinctive forces of life and all kinds of creativity since ancient times and to search for himself for stylistic methods that help him to express to create new and innovative perceptions characterized by aesthetic diversity
Nature is an important entrance to the arts in general and metalworking in particular, so through contemplation and analysis of its elements can discover many diverse systems and ideal proportions that reveal deep secrets of nature that can be used and applied in art to reach the perfection of proportions. The artist sees with his eyes what others do not see. He looks at her in a contemplative and analyzed view of its various shapes, such as the spiral, from which we see many variations, we find it in the ground snail with its spherical shell and we see it in plants, its leaves and stems as we see in the internal seed arrangements of the heart of some flowers and other multiple images in nature. The spiral shape, studied and analyzed, contains aesthetic ratios that correspond to the numerical ratios in the Fibonacci sequence and are also consistent with the golden ratio that achieves perfection.
This research deals with the shape of snails as one of the examples of the spiral in nature by studying and analyzing and linking it to the Fibonacci sequence and the golden ratio as an input to teaching metalwork, where one experimental group of students of the fourth year was selected and a pre-test was conducted for them before teaching with this entrance and another test after teaching it, and a comparison between the results of students ’work. In both, it was found that the students 'dimensional work was better in terms of design, use and distribution of technologies better, which proves the effectiveness of that approach in developing students' design and technical abilities, and the results of the statistical analysis confirmed that.
