After you have studied the concepts involved with Utilitarianism, your assignment is to try to live for one day and “be” a Utilitarian about moral decisions and judgments of others. 

NOTE: You are absolutely under no obligation to act according to any Utilitarian decisions you determine, or express such actual judgments to other people.  Your task is a lot easier than it might seem at first– just see where any decisions and/or judgments you make over the course of one day *could* reflect the view of a Utilitarian: Maybe you can get into it by thinking WWUD? (What Would a Utiliatarisn Do?)
 Your report should describe the situations and decisions/judgments as well as any thoughts you have about applying the viewpoint in your life. If someone around you expresses a judgment or makes a decision that fits Utilitarianism you may include that in your report.
