Microplásticos: abordagem do tema no ensino médio
AI summary Read the abstract
Researchers developed and reviewed experimental approaches for teaching microplastics and environmental pollution in Brazilian high school chemistry classes, connecting hands-on identification and removal techniques to sustainability goals outlined in the UN 2030 Agenda.
A poluição por plásticos tem sido uma das grandes problemáticas socioambientais e, atualmente, novas preocupações estão em destaque devido à onipresença dos denominados microplásticos (MP) em diferentes ecossistemas. Este trabalho de pesquisa apresenta uma proposta de abordagem experimental sobre a temática dos microplásticos e o meio ambiente para aulas de Química no Ensino Médio, com enfoque inicial no levantamento bibliográfico sobre o tema no contexto do ensino básico. A partir do levantamento, foi possível elaborar sequências e/ou práticas de ensino de Química correlacionadas às técnicas de identificação, caracterização e remoção de partículas plásticas e perceber que estas práticas podem possibilitar a inserção de conhecimentos químicos, econômicos e socioambientais conectadas com os Objetivos de Desenvolvimento Sustentável da Agenda 2030 da Organização das Nações Unidas. A pesquisa bibliográfica e a elaboração de práticas sobre microplásticos podem abrir perspectivas para que professores/estudantes de ensino básico as conheçam e as utilizem em contextos de ensino e aprendizagem sobre poluição plástica e química ambiental.

Microplastics in General Secondary Chemistry Education
AI summary Read the abstract
This thesis explored why microplastics, despite being a widely discussed environmental topic, are largely absent from secondary school chemistry curricula in the Czech Republic. The study designed active learning activities to integrate microplastics into general chemistry education, aiming to increase student awareness of associated environmental risks.
Microplásticos No Ensino De Ciências: Revisão Bibliográfica Sobre Estratégias Pedagógicas, Abordagens Ambientais E Lacunas Relacionadas À Saúde Humana
AI summary Read the abstract
A literature review of science education materials found that teaching about microplastics overwhelmingly emphasizes environmental awareness while largely ignoring human health impacts — including evidence that microplastics have been detected in human organs like the liver, lungs, placenta, and breast milk. This gap in curricula limits students' critical understanding of microplastics as a public health issue, not just an ecological one.
Microplásticos: uma abordagem prática para produção de plástico biodegradável como estratégia de educação ambiental no ensino básico
AI summary Read the abstract
Researchers surveyed 146 high school students in Gravataí, Brazil, on their awareness of microplastic pollution and then conducted a hands-on bioplastic production activity as an environmental education intervention. Results showed that approximately 71% of students had limited prior knowledge of microplastics, and the practical activity significantly improved awareness and motivated behavioral reflection about plastic consumption.

AI summary Read the abstract
This experience report describes a secondary school investigative didactic sequence in Brazil on microplastics in the human body, guiding 10th-grade students from initial hypothesis through flipped classroom activities to experimental investigation. The project successfully engaged students with environmental science and raised awareness of personal microplastic exposure.
Microplásticos E Educação Ambiental
