Homework: **This assignment is 100% required** Read all of the quiz questions that you got wrong. On a sheet of paper, list each quiz question that you got wrong. Write the correct answer, and explain how you can tell that is the correct answer. Your answers must explain your reasoning in a way that shows you can get the problem right the next time. For example, if you missed the question "which object is most dense?" your explanation should be something like "object C is the most dense because it is the most crowded inside." You should not write "object C is the most dense because it has the highest density." That isn't helpful. |
