To refresh your memories

• Turn in 1 (ONE) Lab per group (the in-lab
  portion)?
• This is a GROUP activity, and I want to see the
  GROUP work. If you think something different from
  your group, DISCUSS IT.
• Turn in your take home ON TIME
• If you turn it in late, not only will I take off
  points, I will take my time getting it back to
  you.
• On the take home Do your own work. You can work
  together, but copying word for word is not
  allowed. That's called cheating. Letting someone
  copy your take home is also cheating.
