Hi there -- I have some videos that we made on how to use the pipet. They are available as a resource for all to use. http://loncapa.chm.nau.edu/priv/jim/videos/larger/pipet1001.wmv along with some other videos. My question is we want to require students to watch the videos before the lab. Can we check to see if the student clicks on the link to watch the video? thanks -- jim
