Effect: Students are not allowed to chew gum in my class. While some students think that I am just being mean.
Causes: Some irresponsible students make messes with their gum. They may leave it on the bottoms of desks, drop it on the floor, or put it on other people's property. Another reason why I don't allow students to chew gum is because it is a distraction. (write the next ones if you want a more detailed answer or copy this if your fingers are tired :P )
