Cleanliness is a great virtue. Cleanliness is next to godliness. Indeed in some religions, cleanliness is regarded as a part of godliness and is prescribed as a religious duty. Dirt is known to be a fertile propagator of diseases. A classroom is a place where the student pass more or less six hours of the day. The environment of the classroom has some influence on them. So, the classroom must be kept clean in order to ensure a healthy environment. First, the students should bear in mind that a neat and clean classroom makes the students’ minds pure and fresh. The classroom belongs to all the students of the class. Then every student must work to keep it clean. Next, the students should prepare a duty chart for all the students in some groups and the captain should see that each group of students sweep the classroom at least once a month. Finally, the students should keep a basket to drop the unnecessary papers, refuse, and waste materials. The waste kept in the basket should be removed at the end of the last period. All the students should be careful about the cleanliness of the classroom and should keep them aloof from making the classroom unclean and nasty.
