BOOKBAGS STOOLS

• 1. Please leave your bookbag on your regular
  desk.

GETTING STARTED

• Look to whiteboards or front screen to see if
  there are instructions that you can follow
  immediately.

  or to pick up lab sheets or to continue a lab you
  are finishing from the day before.

YOUR MICROSCOPES

  partner.
• Let me know immediately if there is anything
  wrong with your mic.
• Absolutely no tampering with your mic.
• Please let me know if a group from a previous lab
  has left a slide on the stage.

  look like.

  will have to work alone or will be marked
  accordingly.
