**Important! All students must print ALL lab handouts (make a packet) and bring ALL of them to lab every class.  If you choose to use your laptop or tablet to access the handouts from lab, that is ok but there are several handouts that must be printed and turned in for a grade.  If you do not have the lab packet or the handouts that need to be turned in, you will not be allowed to attend lab and that absence will be unexcused!**
















**Lecture Handouts**

Note:  These handouts are not necessarily in chronological order.  Check syllabus for sequence.
