Pincelando a química com aquarelas naturais: Uma proposta para o ensino de química

Abstract

Chemistry is an abstract science due to its representations through symbols of elements and chemical substances. The act of learning chemistry arises from the confrontation between common sense ideas and scientific knowledge. To teach chemical equilibrium, it is common to use natural dyes as facilitators in the process. In the literature review conducted by Almeida et al. (2020), articles published between 2010 and 2020 in science education journals and periodicals were analyzed, and a greater use of acai, beetroot, red onion, and red cabbage was observed due to their low cost, easy availability, and interesting colors. Students can learn chemistry by practicing art, whether through drawings, comic strips, or paintings. It is possible for students to learn the content of pH indicators using natural pigments through watercolor painting techniques using natural dyes obtained from extracting pigments from vegetables such as red cabbage, beetroot, and turmeric. There are several works that involve artistic expression as a tool for teaching sciences, such as chemistry. This integration can assist in the teaching and learning process, enriching it with applications, curiosities, reflections, and fun in teaching abstract chemistry concepts. A project that involves watercolors in chemistry education makes students' learning easier and more meaningful, as they engage with the subject and produce a painting that can express their knowledge in the end. Based on the observations and experiences reported, it can be concluded that there are improvements to be made in the execution and planning of the lesson. The first and most crucial point is to carry out the project for fewer than 15 students, which will result in a more organized classroom and possibly address all students' doubts and questions. Therefore, it is concluded that using art for chemistry education can be very positive and a different experience that allows students to learn meaningfully.
