Abstract

Applying a special technique, a pattern (tattoo) is created on the banana peel. The use of banana peels and other secondary raw materials creates a collage on the theme of nature conservation. In the course of the work, a new technology is tested - testing a banana peel with a toothpick and creating a pattern. The concept of "banana tattoo" is introduced and the phenomenon of oxidation is explained. Creating a sustainable collage on the theme "Let's protect hedgehogs" is an example of sustainable work, the details of which "return" to the second or third use and do not harm the Earth, and the photo of the collage remains and testifies to the children's work. Measures. Secondary raw materials: brown and green plastic bottles, cardboard box, leaflets, banana peel. Toothpicks, sand, gouache. Educational methods. Inclusive story, review of filmed documentaries, practical activities, group work, discussion. Learning strategy. I stage. Familiarity with the oxidation-reduction phenomenon (observation of cut fruit samples: just after cutting and an hour later, clarification of what happened during oxidation). Phase II. Perception of how real tattoos are done (review and discussion of filmed documentary). Stage III. Presentation of the necessary tools for the experiment (conversation-discussion about secondary raw materials, interpretation of the concept of sustainability). Stage IV. Creating a sketch of a drawing (writing a pattern on a piece of paper). Stage V. Performing an oxidation drawing (transferring the created pattern to the banana peel). Stage VI. Creating a collage: sandblasting, bottle cutting, letter cutting, preparation of a “hedgehog”, creation of a sign “Hedgehog Passage”, arrangement of banana peel-needles. Stage VII. Observation of the oxidation phenomenon on banana peels: after an hour, after 4 hours, after a day, etc. Stage VIII. Conclusion, reflection: sustainability, what is difficult, what is new, what I like and so on. Based on the activities, the film “The STEAM Challenge. Oxidation drawing (banana tattoo): https://www.youtube.com/watch?v=DBVWNAjgzG0 Purpose. Apply a special technique on the banana peel to create a pattern (tattoo). Using banana peels and other secondary raw materials to create a collage on the theme of conservation. Tasks of integrated subjects. Knowing the world/science - to look at the natural conditions under which the phenomenon of oxidation takes place, to give examples. Chemistry - get acquainted with the oxidation-reduction process on the banana peel. Art and technology - to learn new art techniques, to create a collage from secondary raw materials. Finish the work neatly. Civic education - to understand that it is possible to use secondary raw materials for a work of art and thus protect nature from pollution. Understand that oxidative drawing can be applied in various advertising, branding projects, marketing. Keywords: STEAM, oxidation drawing, banana tattoo, hands-on activities
