From Maslab 2011
Each team has been assigned a day in which they are to help clean up lab at the end of the day. The assignments are listed on the Calendar. If you can't make your assigned shift, it is your responsibility to trade with another team. If that is not possible or if you cannot make the end-of-Maslab cleaning, contact the staff to discuss how to make up your missed shift.
We also require all teams to show up at noon on the Saturday after IAP ends to help restore lab to the pristine state we got it in. At that time, we require you to return all Maslab-owned equipment that you have, such as the computer from your kit. Cleaning up lab after the end of Maslab is extremely important. If you fail to show up for end-of-lab cleaning (and don't make this up) or fail to return our property, we will fail you.
