Sabrina Hers discusses using classroom recycling for sustainability to teach B2-level grammar (modal verbs, future tenses) and vocabulary. Students respond very positively to hands-on activities, feeling motivated to make a difference. Examples include creating small classroom recycling bins from old items (upcycling), “Thrift Thursday” for clothes swapping, and making posters. This approach also encourages critical thinking about consumerism. Teachers should lead by example and involve students in generating ideas, as their creativity is key.
