Although the PhysioEx activities instruct you to print out your data, you should not do this. The only data I need are those that you write in the book. You should hand in only the pages of the exercises and the pages for the Review Questions. Remember that if you are not required to complete an activity within an exercise (according to the Laboratory Schedule), then you do not need to complete the Review Questions that pertain to that unassigned activity. Of course, you must complete the other Review Questions.
