Hello,
I am a teacher and my students are from 14 to 18 years old.
I have organised an environmental friendly activity few days ago and it was amazing. We live near the seaside, so we have planned to clean the beach near the port. We were 60 students and 6 teachers. We split in 3 groups and each one had a leader. We had different trash bags for collecting plastic, glass, paper and plastic gloves. Our goal was to fill as many bags as possible. We spent 2 hours collecting and at the end we were highly satisfied. We want to repeat this experience.
