In order to facilitate first-day PHYS 105 labs we have made all first-week PHYS 105 labs an online process. While you may complete this lab any time before your second-week lab, we encourage you to complete it as soon as possible, perhaps even at your normal lab time. In order to prepare for this lab you should watch the online one-hour lecture at http://youtu.be/PxWS_HnsPh4 or media directly from www.physics.csbsju.edu/lab/ Most browsers prefer the .webm format for safari: .webm media will download; launch VLC to play or all the .mp4 work directly and read and understand the first lab write up in the lab manual. If the hardcopy lab manual is not available, the text of Lab1 is available now online at www.physics.csbsju.edu/lab/105Lab1.pdf The graded work products for this lab are the online lab quiz starting at: www.physics.csbsju.edu/lab/105Lab1.html and hardcopy of the spreadsheet described in the lab manual and turned in before the start of your second-week lab. Again, we suggest you complete this lab in your normal lab period. The lab rooms (PENGEL 123+121) have computers that will be available for use (but bring your own headphones/earbuds). As the lecture for this lab is rather large for home downloading, we suggest downloading and viewing it on-campus. If you have questions about this lab feel free to ask one of your physics instructors (lab or lecture) or any physicist on the 100 floor of PEngel.
