If you are completing this question before your first lab session, you can either come back to this question after your lab session or you can read through the exercise in the lab module and complete the exercise on your own.   In lab, your group had to come up with a set of criteria to determine whether something is alive and apply it to a list of items.   Write a brief reflection on this exercise that addresses the following questions: How did this exercise expand on or contradict your prior understanding of the definition of life? Were there any items that were surprisingly difficult to categorize as either living or not living? Were there any criteria that were more or less important than you expected? Note: There is no "right" answer here, points will be given for any thoughtful, reasonable answer that addresses all the questions and relates to the lab content.
