(2025-02-11) Santos, Leôncio Silva; Ferreira, Danielle da Silva; Silva, Merylane Porto da; http://lattes.cnpq.br/4940334471477236; Nascimento, Flávia Braga do; http://lattes.cnpq.br/3585720352113766
The objective of this final project is to study the application of a practical experiment that uses red cabbage as a natural pH indicator in chemistry. The term pH is essential in chemistry and is necessary to understand the acidity and alkalinity of solutions. However, students often have difficulty understanding these abstract concepts. This is why education should be more dynamic and interactive. Red cabbage was chosen for this study because it has the ability to change color at different pH levels, making it an easy-to-use and accessible visual resource. The experiment consists of making cabbage extracts and using them to test the pH of various solutions allows students to observe the color changes that reflect changes in pH. The results of the questionnaires and observations administered to the students show that the practical activity arouses curiosity and theoretical understanding of pH. Students reported that they retained more information and were able to apply the ideas to everyday situations. This dissertation emphasizes the importance of incorporating hands-on experiences into chemistry teaching and shows how the use of natural indicators such as red cabbage can improve learning, democratize access to educational resources, and encourage students to experiment. The research findings indicate that this method can be a valuable pedagogical tool that helps create more meaningful and engaging learning.

The training of Chemistry teachers faces significant challenges due to the abstract nature of the subject matter, requiring the adoption of innovative pedagogical methodologies. This study aims to analyze and evaluate the inclusion and implementation of playful activities proposed in the Political-Pedagogical Projects (PPCs) of undergraduate Chemistry programs at public institutions in Alagoas, focusing on the impact of such practices on initial teacher education. The research highlights the use of playful strategies as a pedagogical approach capable of making Chemistry teaching more dynamic, meaningful, and conducive to the development of essential professional skills. Active teaching methodologies, which place students at the center of the learning process, are discussed as effective tools for encouraging participation, autonomy, and critical thinking. The findings indicate that, despite widespread recognition of the benefits of playful activities, their implementation still faces obstacles such as resistance from teachers and students, lack of specific training, and scarcity of appropriate pedagogical resources. However, the analyzed experiences show that, when well-planned and executed, these activities foster greater student motivation, enhance the understanding of abstract concepts, and support the development of socio-emotional skills such as creativity, collaboration, and teamwork. The study proposes a more structured integration of active methodologies into the curriculum, along with ongoing teacher training, in order to promote more engaging and effective teaching practices. By incorporating playful strategies into teacher education programs, it is expected that future Chemistry teachers will be better prepared to face contemporary teaching challenges and deliver a higher-quality education.

The brown propolis, produced by bees of the species Apis mellifera, and geopropolis, generated by Melipona scutellaris, are widely recognized for their significant bioactive properties, such as antimicrobial, antioxidant, and anti-inflammatory activities. This study aimed to characterize the physicochemical properties of geopropolis from the municipality of Maceió and brown propolis from the municipality of Pilar. The samples underwent extraction by maceration and Soxhlet methods, followed by detailed analyses of wax content, loss on drying, ash content, and soluble solids. The results showed that brown propolis exhibited an average mechanical mass of 29.65% in the Soxhlet extraction and 56.9% in maceration, while geopropolis had mechanical mass contents of 75.73% and 75.08%, respectively. The wax content in propolis was 22.44% (Soxhlet) and 31.20% (maceration), exceeding the legal limit in maceration. The loss on drying was 5.81% for propolis, within standards, while geopropolis showed 4.56%. The ash content was 1.87% for propolis and 65.22% for geopropolis, reflecting a higher amount of inorganic material in the latter. The quantification of phenolic compounds revealed 2.02% for propolis (Soxhlet) and 2.80% (maceration), while geopropolis contained 2.74% and 2.22%, respectively. Total flavonoids were 0.011% (Soxhlet) and 0.046% (maceration) for propolis, and 0.039% (Soxhlet) and 1.33% (maceration) for geopropolis. Antioxidant activity, evaluated by the DPPH method, was 31.94% for propolis (Soxhlet) and 73.81% (maceration), while geopropolis showed 75.82% (Soxhlet) and 86.11% (maceration). Additionally, the analysis of volatile organic compounds conducted by Gas Chromatography coupled with Mass Spectrometry revealed the presence of 66 compounds in brown propolis and 48 compounds in geopropolis. The diversity of volatile compounds, including esters, terpenes, and phenols, highlights the potential of these substances for therapeutic and industrial applications. These results indicate that both propolis and geopropolis possess high levels of bioactive compounds, marked by their strong antioxidant activity, suggesting considerable therapeutic potential. The physicochemical characterization of these substances is of great importance for the municipalities of Pilar and Maceió, as it enhances local natural resources and opens opportunities for the development of apicultural products with industrial and medicinal applications.

This Final Course Work aims to analyze the methodologies used to teach chemistry that favor the learning of students in Youth and Adult Education (EJA). It seeks to answer the research problem: what methodologies do chemistry teachers use for EJA students' learning? Its general objective is to improve the quality of teaching for EJA students by focusing on methodologies that use everyday life to contextualize the subject of chemistry in order to lead EJA students to understand the subject of chemistry in a clear way. This work uses bibliographic research as its methodology. Having a qualitative character, a survey of the texts that served as data for the bibliographic research was carried out, with filters in the search: open access, article, period from 2019 to 2024, national productions. The results show that teaching chemistry in EJA faces specific challenges, given the diversity of experiences and needs of students. The traditional approach proves to be ineffective for this audience. Active, contextualized and dialogic methodologies, which value students' prior knowledge and connect chemical content to their daily lives, have shown to be more promising. The importance of teacher training is highlighted, emphasizing the need to prepare them to deal with the particularities of this audience and to use innovative and inclusive methodologies, valuing dialogue and pointing it out as an effective strategy to make chemistry teaching more meaningful and engaging for EJA students.

The difficulty high school students have in understanding technical chemistry content, such as physical chemistry and electrochemistry, highlights the need for innovative teaching methodologies that make learning more accessible and meaningful. Given this scenario, this study used storytelling as a teaching strategy for teaching chemistry, with the aim of promoting greater engagement, contextualization, accessible language, and knowledge retention. To this end, the specific objectives defined were to analyze the recurrence of physical chemistry and electrochemistry content in the ENEM (2020-2024) exams, develop and apply pedagogical proposals using narratives, and evaluate the impacts of this methodology on the teaching and learning processes. The research had a qualitative, quantitative, and exploratory approach, structured in three stages: statistical analysis of the chemistry questions on the exam, bibliographic review on active methodologies and storytelling, and elaboration of a pedagogical proposal. Two activities were developed: “Statue Oxidation” and “Battery Storytelling: Improper Disposal”, which contextualize chemical concepts through interactive and interdisciplinary narratives. The results revealed that the use of the narrative resource favors the understanding of the content, stimulates student participation and contributes to the development of critical and reflective skills. The strategy was aligned with the guidelines of the National Common Curricular Base (BNCC), although its implementation still faces challenges related to teacher training and school infrastructure. It is concluded that the narrative proposal is a promising approach for teaching chemistry, and its application in different educational contexts is recommended.

(2025-07-08) Barbosa, Cândida Caroline da Silva; Ferreira Júnior, Jésu Costa; http://lattes.cnpq.br/5859354241648167; Silva, Leonardo Vieira da; http://lattes.cnpq.br/3401495568705461; Azevedo , Edmar Marinho de; http://lattes.cnpq.br/2213926589443334
This study investigates the use of educational videos as a complementary pedagogical tool in teaching Organic Chemistry, particularly in experimental classes taught in Technical High School Chemistry courses at the Federal Institute of Alagoas (IFAL), Maceió Campus. The main objective is to address the difficulty many students face in connecting theory and practice with the content studied, including a lack of familiarity with the materials and reagents that will be used during laboratory classes. Thus, the proposal aims to promote a more dynamic (using visual resources and accessible language), contextualized (relating the content to everyday experiments), and meaningful (encouraging students' understanding and proactive role in experimental practice) teaching-learning process. Three demonstration videos of experiments included in the curriculum for third-year Technical High School students were produced and applied. All videos exclusively address extraction techniques, as this is a thematic focus defined in the research. The techniques used were: (i) solid-liquid extraction of caffeine, (ii) extraction using a Soxhlet apparatus, and (iii) acid-base extraction of Doril components. The videos were watched before the experiments. Before the practical classes and after watching and completing the practical classes, students completed questionnaires on the concepts and laboratory practices on Google Forms. The results demonstrated a significant improvement in understanding the concepts and conducting the experiments, indicating that the audiovisual resource contributes to student preparation, reducing doubts and increasing performance in the practical classes. Student evaluations of the pedagogical tool highlighted its clarity, usefulness, and appropriate structure. Therefore, the use of educational videos, integrated in a planned manner into the pedagogical process, achieved the proposed objectives and proved to be an effective tool for teaching Organic Chemistry practices, fostering knowledge construction in a more accessible, interactive, and meaningful manner.
