    Impactos ambientais causados pelo descarte inadequado de pilhas e baterias
    (2022) Santos Júnior, Ronaldo dos; Oliveira, André Luiz dos Santos; Oliveira, André Luiz dos Santos; Barbosa, Amaury Franklin Benvindo; Silva, Kleyfton Soares da; Santos, Renan Atanazio dos
    Faced with the increasing advancement of technology, the production of cells and batteries has grown continuously. However, in their compositions they present highly toxic components called heavy metals, so when they are incorrectly discarded, they cause contamination in the environment and human health. Thus, this work aimed to show the impacts caused by the incorrect disposal of the same. The methodology involved research using articles, academic dissertations, journals and websites. A literature review was carried out between January and April 2022, in the following database: Google Scholar. With improper disposal, contact with moisture, water, heat and other chemicals is enough for toxic components to leak and mass contamination ensues. Taking as an example the environmental accident that happened in Bauru in 2002, where 314 children were contaminated by lead, causing blood lead and irreparable damage. In Brazil, there are currently some projects aimed at correct disposal, an example of which is recycling. In most treatment processes, a sorting takes place, with the aim of treating each type of electronic waste. This procedure (recycling) is promising and can be applied in serval places.

    Proposta de reciclagem das cascas de camarão descartadas às margens do Rio São Francisco em Piaçabuçu como instrumento de conscientização e preservação ambiental
    (2022) Santos, Amanda Beatriz Mendes dos; Oliveira, André Luiz dos Santos; Oliveira, André Luiz dos Santos; Barbosa, Amaury Franklin Benvindo Barbosa; Costa, Danielle de Lima
    Piaçabuçu, inland in the southern region of Alagoas, stands out as an important fishing center in the state. In the municipality, a good part of the population survives from the processing of shrimp coming from artisanal fishing and from nurseries. However, after the shrimp are processed, the waste is thrown on the banks of the São Francisco River. The environmental impact that this practice can generate motivated the present work. This work aimed to present ways to reuse shrimp shells mitigating the environmental impact. The methodology involved research using articles, academic dissertations, journals and websites. In search of alternatives for the use of shrimp processing residues. Several proposals for the reuse of shrimp shells have emerged with the aim of using it. The manufacture of flour presents itself as a viable option due to its simple synthesis methodology, which can be carried out in an high nutritional value and can be used as animal feed. The proposal is promising and can be applied in several fishing communities.

    Teoria e prática: uma proposta de Sequência Didática utilizando microscópio caseiro no ensino de ciências
    (2022) Santos, Rayane Lima dos; Oliveira, André Luiz dos Santos; Oliveira, André Luiz dos Santos; Silva, Kleyfton Soares da; Nascimento, Raul César da Silva
    The search for meaningful learning continues to be a challenge for many teachers, who need to plan their classes with the objective of achieving teaching that meets the needs of students. This work aimed to propose a didactic sequence for the teaching of "cytology" in the 1st year of high school, based on the Theory of Didactic Situations (TSD), having as a starting point the use of a homemade microscope. The methodology involved a qualitative and bibliographical research, seeking to suggest a teaching model based on TSD, which consists of the application of four phases: action, formulation, validation and institutionalization. The proposal is promising and can be applied in different curricular contents.

    Utilização racional da água em hidroponia de baixo custo como instrumento de conscientização e preservação ambiental
    (2022) Ferreira, Almira Silva; Oliveira, André Luiz dos Santos; Oliveira, André Luiz dos Santos; Lenz, Tiago de Moraes; Dantas, Emerson de Oliveira
    The water crisis is one of the main problems that human beings face nowadays, being one of the most reported issues internationally. Thus, making it necessary to search for alternatives aimed at sustainable agriculture, hydroponics, a soilless cultivation technique, seeks a way to mitigate the problems of water scarcity in agriculture, and can be implemented in places with little availability of water resources and thanks to its low cost, it can be mounted on small properties and/or residences. Given the above, the main objective of this work is to analyze and explain, based on bibliographic reviews, issues and factors related to the rational use of water in low-cost hydroponics as an instrument of awareness and environmental preservation. For this, a micro-scale, experimentation of a homemade hydroponic system for the cultivation of coriander was carried out. With the studies, we concluded that the cultivation by the hydroponic system proved to be viable, profitable and mainly contributed to environmental conservation in terms of saving water and not using pesticides.
