There is a post-lab for exp 15. You can find the proper link in the syllabus (page 7), on my web page, the Course Home page in Carmen and the "Content" tab in Carmen. It is an on-line data entry post-lab just like the pre-lab. It is due when your report is due (i.e. needs to be completed before going to lab the day the report is due). Dr. Zellmer
