Scenario 1: In this situation, I would take the $10 bill to the lost-and-found. While it may be tempting to keep the money for myself, I believe it is important to act ethically and do what is right, even if it means potentially losing out on something. Additionally, if the money does belong to someone, it is important to return it to them, as it may be a significant amount for them.
Scenario 2: I would not consider it cheating to compare my answers to my neighbor's, as long as I am not copying their answers directly or using them to improve my own score. However, if I did decide to compare answers, I would make sure to do so discreetly, so as not to disrupt the class or cause any issues.
Scenario 3: I would not change the grades on the score sheet, even if I know I will not get caught. As a teacher's assistant, it is my responsibility to accurately record the grades that are given, and altering them would be a breach of that responsibility. In addition, changing grades would not be fair to the students who worked hard to earn their grades, and could potentially have serious consequences if discovered.
Scenario 4: I would report the students to my teacher, as it is my responsibility to notify a trusted authority if I suspect that something harmful or illegal may be occurring. Even if the students' plans are just for harmless pranks, it is important to let the teacher know so that they can address the situation and ensure the safety of all students.
Scenario 5: I would not turn in the fixed-up review as my own homework assignment, as this would be considered plagiarism. Plagiarism is the act of presenting someone else's work as your own, and it is not only unethical, but it can also have serious consequences in academic settings. Instead, I would spend the time to write my own essay on the assigned topic, even if it means staying up late or working harder to complete the assignment.
