Instructions

• In todays special Valentines edition of the
  Science ATC lesson, you will be reminded of why
  its so great to love chemistry. As we embrace
  the love for chemistry, we must also take into
  account the danger behind this beautiful science
  and our responsibility to follow lab safety.
  Enjoy the video and answer the questions on the
  following slides. Please hand in your assignment
  to your loving science teacher by the end of the
  week.

  of chemical vapors toward the nose as a means to
  detect odors in a test tube is to
•  
• A avoid experimental error from excessive loss of
  mass of reactants or products
• B avoid splashing chemicals into the face of any
  person
• C protect the respiratory tract against
  potentially harmful vapors
• D determine the relative strength of the odor
  before smelling directly
