Pre-labs

You will use pre-labs to convince your instructor that you are knowledgeable enough to safely
perform the scheduled experiment. You need to do three things to demonstrate this:

1. Pre labs are first and foremost about safety. You need to know the hazards of the
experiment that you are about to perform. You should include a list of chemicals and
research their hazards by looking up and summarizing the information on their Safety Data
Sheet.

a. Always include the chemical reactions you are doing. List the reagents, product, and
waste.

1. Pre labs show that you will efficiently go about your work. You will outline the procedure in
   your own words. You will include prepared tables and equations that are required to record
   and perform required calculations.
2. You will work out and show the results of the pre lab questions. These questions are
   designed to demonstrate your preparation.
   1. Find and do the Laboratory Preparation and Prelaboratory Assignment for each lab
      in your lab manual.
   2. Handouts should be read carefully to determine if there is a pre lab component – it
      is up to you to do this without your TA telling you to do so.

Pre labs are type written (use equation editor in MS word to make equations)1 and submitted to
Canvas electronically in MS Word docx format ONLY. NO MACROS. Corrupt or virus ridden files will
receive a score of zero. Show care in your work.

Pre labs are due 24 hrs. before the start of the lab. Your instructor can bar you from performing
the experiment (and you’ll receive a 0) if your Pre lab is poor – you represent a safety hazard to yourself
and others.
