El objetivo del estudio fue determinar la influencia de una propuesta didáctica basada en química verde en el desarrollo de la conciencia ambiental de estudiantes de enseñanza secundaria. La metodología respondió a un diseño cuasi experimental, de enfoque cuantitativo, correlacional y descriptivo, con dos grupos: control y experimental. Participaron 40 estudiantes distribuidos en cuatro centros educativos, a quienes se aplicó un test de base estructurada antes y después de la intervención. El instrumento fue validado por juicio de expertos y alcanzó un alfa de Cronbach de 0,88, valor considerado muy confiable para interpretar la consistencia interna de las mediciones. La propuesta, denominada QuimVerde-AR, integró actividades de indagación, análisis de residuos, sustitución de materiales peligrosos, prevención de contaminación y toma de decisiones ambientales contextualizadas. Los resultados evidenciaron que el grupo experimental obtuvo mayor incremento en conocimiento de principios de química verde, prevención de riesgos, argumentación socioambiental y compromiso con prácticas sostenibles. La prueba t de Student mostró diferencias significativas entre grupos en el postest, mientras que la d de Cohen indicó un efecto alto de la intervención. Asimismo, la correlación de Pearson mostró asociación positiva entre la participación en actividades verdes y la conciencia ambiental final. Se concluye que la química verde, cuando se enseña mediante experiencias activas y contextualizadas, fortalece destrezas científicas, pensamiento crítico y responsabilidad ambiental en secundaria.
