Plastic, secondary education, pollution


Plastic pollution is found in marine and terrestrial ecosystems. Plastics can enter the food chain and these may accumulate in aquatic species’ organs or humans [1]. People’s attitude towards nature represents the driving force behind the commitment to ecological behaviour [2]. It is necessary to raise environmental awareness at school. For this purpose, a study was carried out with 40 Spanish grade-8 (13-14 years) students from a high school in Malaga. First, the students answered a survey on their knowledge of plastics. Secondly, a design and application on a teaching learning sequence on critical thinking and plastics was carried out [3]. The teaching learning sequence consisted of murals and presentations on the types of plastics, an inquiry into different plastics [4], a role play about the ban single-use plastics, and an audio story. Finally, they did the same survey as post-test. After the educational experience, post-test result was better that pre-test results and students demonstrated an improvement in their attitudes.
