Answer 1

These students are ill mannered and do this only for fun but we can make them understand not to do this as it is very bad habit to make our own classroom dirty. Teachers should appoint some sincere students to look after these deeds.Strict rules and regulations should be made and students shouls be punished if they violates this rules.Teachers can warn all the students particularly those who are found to be involved in the littering of classrooms.It will surely work and children would stop doing all this.

Answer 2

Student do this for enjoy only. They don't care about pollution. There should be strict rules in school regarding pollution. Teacher should give the authority to monitor that if any student do this non sense things monitor will tell to teacher. So that, teacher can take action towards those students. We can also convince them that our class is like our home, will anyone want to pollute their home. We can make them understand this way.
